HP Blogs – 6 steps for SMBs to become IPv6-ready – The HP Blog Hub

My Comments

There is all the talk of us running out of IPv4 public IP addresses for the Internet, and an increased awareness of IPv6 Internet technology. One major driver for the IPv6 technology is the rolling out of next-generation broadband services; where this feature will be seen as being part of the “next generation” mould.

In the near time, the typical IPv6 network will operate as a “dual-stack” setup where there is an IPv6 network and an IPv4 network operating over the same network space. A device such as an IPv6-ready router will typically bridge the gap between the dual-stack devices and the IPv4-only devices by assisting in the discovery of the devices and transferring data between the two different network stacks.

Outside IT contractors

If you do regularly engage outside contractors for your IT needs such as your POS / property-management technology, it would pay to ask whether the technical staff know about IPv6 and how to deploy it. Most of these contractors may think that small business doesn’t need IPv6 but as the Internet moves to this technology, it pays to be future-proof.

ISPs and Webhosts

It is worth making sure that your business’s ISP and Internet hosted services such as your Webhost are ready for IPv6 or have intentions to roll out a customer-facing IPv6 service.

Most ISPs and Webhosts are likely to have the backend of their services working on IPv6 technology but their customer-facing services like the Web services or Internet service may not be ready. This may be due to the presumption that most customer setups will fail when confronted with IPv6. The exception may be the ISPs that serve a “switched-on” audience that knows their way around the Internet technology; or ISPs and Webhosts that offer customer-facing IPv6 service as a limited-user beta test and they may offer a “dual-stack” setup.

It also pays to check that your domain host supports domain records that are compatible with IPv6 setups. This includes having AAAAA-form DNS records that can resolve your domain name to IPv6 addresses.

Hardware

Computers that run Windows Vista or 7, MacOS X Lion or recent Linux distributions will be ready for IPv6; with Windows XP having support through a downloadable module from Microsoft’s Web site. Relatively-recent computer equipment can be upgraded from prior operating systems to the newer IPv6-compliant operating systems. For the mobile platforms, the IOS (iPhone / iPad / iPod Touch), Android, Symbian and Windows Phone 7 platforms do support IPv6. They will typically operate on a “dual-stack” arrangement by being able to service an IPv4 network and an IPv6 network at the same time through the same network interface,

Similarly, most network printers pitched at the business end of the market that were released over the last few years would have support for IPv6 in a dual-stack setup.

As for routers, managed switches, access points and other network hardware, I would suggest that you check for firmware that supports IPv6 for your existing equipment. Keep an eye on the manufacturer’s Website for newer firmware updates that support IPv6.  If you are purchasing or specifying newer network equipment, make sure that it does support IPv6 or has future support for this in a planned firmware update. Most unmanaged switches, HomePlug-Ethernet bridges and devices that don’t use a Web or SMNP user interface would not need to be compliant with IPv6. This is because these devices work at levels below the IP stacks.

In the case of routers, the device should work as a “dual-stack” unit with support for routing between the two different IP network types. It should also be able to cope with working with a dual-stack Internet service especially as the business Internet services that provide IPv6 will do so in a dual-stack manner.

When I review any network hardware including printers, I will identify those pieces of equipment that are IPv6-ready so as to help you know whether the equipment will be future-proof.

Software

As for software on these computers, any desktop firewall software or other network-utility software that you run would need to support IPv6 operation. This is something that recent versions of this software would cater for, but you should make sure of this when you specify new software. It also holds true for any other network-management programs that need to work on an IP level.

The application software that serves office functionality or line-of-business needs wouldn’t be of concern in relation to IPv6 because the operating system would be handling the network-resource requests for these programs.

Conclusion

The key issue with assuring IPv6 compatibility for your small business network is to make sure that your computer equipment works on dual-stack IPv4/IPv6 software and / or there is a router that works as n IPv4/IPv6 bridge on both sides of the network-Internet “edge”. As well, the IT contractors and services that you engage would need to be knowledgeable about IPv6 and the impending rollout for your business.

Introduction

Alastair MacGibbon - Centre For Internet Safety (University of Camberra)

I have been invited to do an interview with Alastair MacGibbon of Centre For Internet Safety (University Of Canberra) and Brahman Thiyagalingham of SAI Global who is involved in auditing computing service providers for data security compliance.

This interview and the presentation delivered by Alastair which I attended subsequently is about the issue of data security in the cloud-driven “computing-as-a-service” world of information technology.

Cloud based computing

We often hear the term “cloud computing” being used to describe newer outsourced computing setups, especially those which use multiple data centers and servers. But, for the context of this interview, we use this term to cover all “computing-as-a-service” models that are in place.

Brahman Thyagalingham - SAI Global

These “cloud-based computing” setups are in use by every consumer and business owner or manager as they go through their online and offline lives. Examples of these include client-based and Web-based email services, the Social Web (Facebook, Twitter, etc), photo-sharing services and online-gaming services. But it also encompasses systems that are part of our everyday lives like payment for goods and services; the use of public transport including air travel; as well as private and public medical services.

This is an increasing trend as an increasing number of companies offer information solutions for our work or play life that are dependent on some form of “computing-as-a-service” backend. It also encompasses building control, security and energy management; as well as telehealth with these services offered through the use of outsourced backend servers.

Factors concerning cloud-based computing and data security

Risks to data

There are many risks that can affect data in cloud-based computing and other “computing-as-a-service” setups.

Data theft

The most obvious and highly-publicised risk is threats to data security. This can come in the form of the computing infrastructure being hacked including malware attacks on client or other computers in the infrastructure to social-engineering attacks on the service’s participants.

A clear example of this were the recent attacks on Sony’s online gaming systems like the PlayStation Network. Here, there was a successful break-in in April which caused Sony to shut down the PlayStation Network and Qriocity for a month. Then, a break-in attempt on many of the PlayStation Network accounts had taken place this week ending 13 October 2011.

The attack on data isn’t just by lonely script kiddies anymore. It is being performed by organised crime; competitors engaging in industrial espionage and nation states engaging in economic or political espionage. The data that is being stolen is identities of end-users; personal and business financial data; and business intellectual property like customer information, the “secret sauce” and details about the brand and image.

Other risks

Other situations can occur that compromise the integrity of the data, For example, a computing service provider could become insolvent or change ownership. This can affect the continuity of the computing service and the availability of the data on the systems. It also can affect who owns the actual data held in these systems.

Another situation can occur if there is a system or network breakdown or drop in performance. This may be caused by a security breach; but can be caused by ageing hardware and software or, as I have seen more recently, an oversubscribed service where there is more demand than the service can handle. I have mentioned this latest scenario in HomeNetworking01.info in relation to Web-based email providers like Gmail becoming oversubscribed and performing too slowly for their users.

Common rhetoric delivered to end-users of computing services

The industry focuses the responsibility of data security for these services on to the end-users of the services.

Typically the mantra is to keep software on end computers (including firmware on dedicated devices) up-to-date; develop good password habits by using strong passwords that are regularly changed and not visible to others; and make backup copies of the data.

New trends brought on by the Social Web

But there are factors that are being undone by the use of the Social Web. One is the use of password-reset questions and procedures that are based on factors known to the end user. Here, the factors can be disclosed by crawling data left available on social-networking sites, blogs and similar services.

Similarly, consumer sites like forums, and comment trees are implementing single-sign-on setups that use credential pools hosted by other services popular to consumers; namely Google, Facebook and Windows Live. This also extends to “account-tying” by popular services so that you are logged on to one service if you are logged on to another. These can create a weaker security environment and aren’t valued by companies like banks which hold high-stakes data.

The new direction

As well, it has been previously very easy for a service provider to absolve themselves of the responsibility they have to their users and the data they create. This has been through the use of complex legalese in their service agreements that users have to assent to before they sign up to the service.

Now the weight for data security is now being placed primarily on the service providers who offer these services to the end users rather than the end users themselves. Even if the service provider is providing technology to facilitate another organisation’s operations, they will have to be responsible for that organisation’s data and the data stream created by the organisation’s customers.

Handling a data break-in or similar incident

Common procedures taken by service providers

A typical procedure in handling a compromised user account is that the account is locked down by the service provider. The user is then forced to set a new password for that account. In the case of banking and other cards that are compromised, the compromised account cards would be voided sot that retailers or ATMs seize them and the customer would be issued with a new card and have to determine a new PIN.

The question that was raised in the interview and presentation today is what was placed at risk during the recent Sony break-ins. The typical report was that the customers’ login credentials were compromised, with some doubtful talk about the customers’ credit-card and stored-value-wallet data being at risk.

Inconsistent data-protection laws

One issue that was raised today was inconsistent data-protection laws that were in place across the globe. An example of this is Australia – the “She’ll Be Right” nation. Compared to the USA and the UK, Australians don’t benefit from data-protection laws that require data-compromise disclosure.

What is needed in a robust data-compromise-disclosure law or regulation is for data-security incidents to the disclosed properly and promptly to the law-enforcement authorities and the end-users.

This should cover what data was affected, which end-users were placed at risk by the security breach, when the incident took place and where it took place

International issues

We also raised the issue of what happens if the situation crosses national borders. Here nations would have to set out practices in handling these incidents.

It may be an issue that has to evolved in the similar way that other factors of international law like extradition, international child-custody/access, and money-laundering have evolved.

Use of industry standards

Customers place trust in brands associated with products and services. The example that we were talking about with the Sony data breach was the Sony name has been well-respected for audio-visual electronics since the 1960s. As well, the PlayStation name was a brand of respect associated with a highly-innovative electronic gaming experience. But these names were compromised in the recent security incidents.

There is a demand for standards that prove the ability for a computing service provider to provide a stable proper secure computing service. Analogies that we raised were those standards that were in place to assure the provision of safe goods like those concerning vehicle parts like windscreens or those affecting the fire-safety rating of the upholstered furniture and soft-furnishings in the hotel that we were in during the afternoon.

Examples of these are the nationally-recognised standards bodies like Standards Australia, British Standards Institute and Underwriters Laboratories. As well there have been internationally-recognised standards bodies like the International Standards Organisation; and industry-driven standards groups like DLNA.

The standards we were focusing on today were the ISO 27001 which covers information security and the ISO 20000 which covers IT service management.

Regulation of standards

Here, the government regulators need to “have teeth” when it comes to assuring proper compliance. This includes the ability to issue severe fines against companies who aren’t handling the data breaches responsibly as well as mitigation of these fines for companies who had an incident but had audited compliance to the standards. This would be demonstrated with evidence of compliant workflow through their procedures, especially through the data incident.

As well, Brahmin had underscored the need for regular auditing of “computing as a service” providers so they can prove to customers and end users that they have procedures in place to deal with data incidents.

I would augment this with the use of a customer-recognisable distinct “Trusted Computing Service Provider” logo that can only be used if the company is compliant the the standards in their processes. The logo would be promoted with a customer-facing advertising campaign that promotes the virtues of buying serviced computing from a compliant provider. This would be the “computing-as-a-service” equivalent of the classic “Good Housekeeping Seal” that was used for food and kitchen equipment in the USA,

Conclusion

What I have taken from this event is that the effort for maintaining a secure computing service is now moving away from the customer who uses the service towards the provider who provides the service. As well, there is a requirement to establish and enforce industry-recognised standards concerning the provision of these services.

What are QR Codes

QR code used in a newspaper to link to its mobile site

A QR Codes is a two-dimensional monochrome barcode that is designed to house a long text string. This may represent contact details or Wi-Fi network parameters but is commonly used to provide a link to a Web-hosted resource. These barcodes may be printed on a newspaper, business card or flyer; or even shown on a Website; the latter method being used to show links to software for the Android platform.

Typically, a person who has a mobile phone equipped with a QR-code reader app can then just point the phone’s camera to the barcode and “take a picture” of that barcode. This then leads to the contact details being put in their contact list or the user being taken to the Web site or Web-hosted resource. This function has even been extended to supplying GPS coordinates to a device for navigation (think of geocaching) or, in the case of Android phones, supplying Wi-Fi service parameters to these phones as part of provisioning hotspot service.

A QR code as used on a poster to advertise this site

They are popular in Europe especially with cafes and restaurants but are slowing increasing in popularity in other countries. As well, some commentators have described the QR code as a way of providing a machine-readable hyperlink in the field. It is also worth having a look at various QR-code blogs like this one so you can know what the trend is about.

Infact, when I promote HomeNetworking01.info using posters or business cards, I make sure there is a QR code pointing to the site so that people can use their phones to head to the site.

Why QR codes for your organisation

One major benefit that QR codes have for your print-based campaigns is that you can insert a direct link to your Webpage or a resource on that Webpage. Your audience then can visit that resource without having to memorise a URL or transcribe the URL in to the phone using a small touchscreen keyboard or SMS-style with the phone keypad.

The QR code is better than using Bluetooth transmitters to provide content. This is because the user isn’t likely to be annoyed with “accept this” Bluetooth responses from these transmitters when they come in to range of the transmitters. As well, the user doesn’t have to remember how to enable or disable Bluetooth discovery mode on their device. As well you don’t need to make sure there is a transmitter at the advertisement and make sure there is power to the transmitter, which can make the QR code acceptable even for posters on that noticeboard or shop door.

It is also better than using any of the proposed “near-field communication” technology for linking to Web resources because you don’t need to buy and integrate near-field transmitters in your promotional materials for the technology to work.

Direct Link to deep Web resources

You may want to provide a sound clip, video or PDF file to your mobile users. As well, you may want to link the user to a particular Web page about a product or promotion. But mobile users may find these resources difficult to gain access to on your site because of being required to enter a long URL into that numeric or small alphabetic keypad.

The QR code can provide the direct link to your campaign page, PDF file or audiovisual resource in a manner that is ready to download “there and then”. If the resource is a YouTube video, you can provide the link to the video clip as it appears on YouTube and the site or local YouTube client can open when the QR code is scanned.

Appropriate for the Social Web

Here, the QR code can augment your Social Web campaign because most active Social-Web users tend to work their Facebook or Twitter presence more from their smartphones. This is especially as I have noticed a lot of small businesses promote their Facebook presence online through posters and flyers that have the “Like us on Facebook” slogan.

What a simplified way of doing this by pointing the latest ultra-cool iPhone to the QR code on the poster attached to the trendy cafe’s espresso machine or refrigerated display cabinet in order to “like” that cafe on Facebook. It certainly makes it certain that you are seen with that iPhone.

Reading QR Codes

Some mobile-phone carriers and manufacturers will supply a QR-code reader with their Internet-enabled camera phones. But iPhone, Android, Blackberry and Windows Phone 7 users can come across many free QR-code readers at their platform’s app store. One example that comes to mind is the free i-Nigma which started becoming available for the iOS platform but lately became available for the Android and Blackberry platform. There are others like Barcode Scanner for the Android platform, BeeTag for the Blackberry platform and ScanLife for most of the platforms.

A main difference that may sort the “sheep from the goats” as far as QR-code reader programs go is whether they can read a light-coloured QR code that is printed on a dark surface. Similarly, there may be differences in how well a difficult-to-read code like a double-sided sign that is backlit can be understood.

At the moment, most QR-code readers are pitched at handheld mobile phones for immediate viewing of the resources on these devices. But it could be feasible to provide “capture-store-sync” transfer of Web URLs or downloaded resources to desktop operating systems or tablet computers as a feature of a QR-code reader. This could then allow a person to view the Web site on their laptop computer using their favourite Web browser at a later time.  It would also be of importance with QR codes being used for presenting Wi-Fi network parameters to Android phones, where the same parameters can be passed up to a laptop and integrated in to the Wi-Fi networks list for that computer.

Preparing QR codes

There are many QR-code generator sites and programs, most of which are free to use. Typically these sites may allow you to provide a URL to a resource as the input text or prepare contact details. A good resource to start from is this blog’s list of the top 10 free QR-code generating sites. As well, i-Nigma also offer a free QR-code generating page as well as their QR-code reader. Yet another resource is the QReateBUZZ Webpage which I have used for the QR codes for promoting this site.

These codes can be yielded as a small, medium or large size. Here, you could use a small size code for business cards and flyers here you don’t have much room or just want a discreet code on the corner of the poster. You could then use the larger sizes if you want people to notice that there is a QR code in the signage’s artwork or need to be far from the artwork to scan it.

Most sites will yield high-resolution PNG or JPEG bitmaps but some may yield EPS Postscript files or PDFs that are vector-images of the QR codes. You typically will then copy-and-paste or import the mage in to your artwork. As well, a lot of the sites will generate a JPEG image that you copy from the site using Ctrl-C / Command-C and paste to your artwork using Ctrl-V / Command-V.

Of course, there are some desktop QR-code generator programs which will run on a regular computer but most of these are Windows-only and a lot of them are offered at “large-business” prices.

It is still good practice to work with dark-graphics-against-light codes because most QR-code readers cannot work effectively with light-graphics-against-dark at the moment. If you are setting a QR code on a dark background, you could use the dark graphic on a light background and have a distinct light-background margin around that barcode.

Conclusion

Once you explore the creation and use of QR codes as part of your online and offline marketing strategy especially where you have online resources

Another increasingly-popular social network service is Twitter. This was intended as a “microblogging” service but some people have been implementing it as another social network.

Like the similar Facebook article that I have written for Facebook novices, this will list who will see which information you post when you use Twitter. Here, I would recommend this as a bookmark or favourite or as something to print out and keep near the computer or have available on the business intranet.

Twitter lexicon

Who sees what

What to do where on Twitter

If someone follows you on your Twitter account, it may be a good idea to check that person out when you receive the notification by email. Here, you could then consider following that person and being able to use direct messaging as appropriately.

It is also worth noting that a lot of social Twitter users use “textspeak” (abbreviations and acronyms for common expressions used when sending SMS messages) when they send out Tweets. So you may have to use resources like the Urban Dictionary to help you understand some of this lingo.

Introduction

You might be considering setting up that complimentary hotspot for your guests to use but there are certain risks to be aware of concerning the security of your business and your guests’ data and identity.

Risks that have been highlighted include confidential-data and identity theft performed against customers as they work this data from their portable devices; as well as clandestine computer activity like the downloading or serving of illegal content; or the distribution of spam email, performed using computers connected to public Internet networks like wireless hotspots.

As well, there may be other imperatives required of people who provide Internet access to the public. These imperatives, asked for by various local, state / regional or national governments may include requirement like keeping a log of whom you provide Internet access to or requirement for session tracking. Therefore I am not therefore in a position to explain how to satisfy these needs and it is best to seek local advice on this topic.

Therefore, your business should know who is using the hotspot service and be able to make sure that the people who benefit are the business’s customers or guests. This means that the customers or guests are actually going to be operating the network device that they use when connecting to the service and also operate it on your premises. As well, your customers know that they are going to actually benefit from your hotspot service when they log in to this service.

The cafe or bar as a “second office”

This is more important for the cafe as an increasing number of businesspeople use these places as “second offices” where they can work without unnecessary office-borne distraction or as places where they meet their colleagues or business partners. Here, these people will be working on workplace-confidential data and most of these workplaces place high value on the security of this data as it travels between the laptop and the workplace’s main computer systems.

In fact, the reason I have decided to publish this article was because a cafe that I regularly visit in Camberwell (Melbourne, Australia) had just started to offer free public Wi-Fi access but I had wanted them to provide a free Wi-Fi service that is safe for their customers. Here, they had an ordinary wireless router as the Internet service but they needed help in getting this service working properly and safely. They also wanted to make sure that this resource was available just to their customers as part of their customer service.

Your equipment

When you start out with your complimentary-use hotspot service, you may use a wireless router hooked up to a separate Internet service or use one with a “guest-access” or hotspot function and is connected to your common Internet service.

This should be set up to cover your public area such as the bar areas in your bar or the dining room in your cafe. In some situations, you may need to use an additional access point to cover larger areas or get your signal past thick walls. This is something I have covered in this site as a separate article.

As well, if your equipment works on 802.11n technology, it should be set to work in compatibility mode where it can work with 802.11g and 802.11n devices. This is to cater for the fact that most devices that are in circulation, especially smartphones, are likely to work with 802.11g technology and people may operate battery-operated 802,11n-capable devices in 802.11g mode in order to conserve battery runtime. 

Your SSID or Network Name

The SSID or network name is very important to your hotspot’s identity. Here, it should reflect your business’s name and have a reference to public or guest Wi-Fi service. An example that I used for a basic complimentary-use Wi-Fi hotspot that I set up at a coffee lounge just recently was MORAVIA-PUBLIC-WIFI. Here this reflected the coffee lounge’s name (MORAVIA) as well as stating that the service was a public Wi-Fi hotspot service hosted by this business. Therefore, you can then identify any “evil-twin” or “fake-hotspot” devices left on or near the premises that exist to capture customers’ sensitive data.

This SSID must be used in all signage advertising your hotspot and the signage must reflect your company’s identity. This means that it either has your company logo and name or be in your company’s styling. In this case, the signage about the hotspot should at least exist beside the cash-register and the door, preferably at eye-level or near the main handle or pull.

Hotspot security

Basic security

Your hotspot network should be secured with a WPA-PSK passcode which your staff should give out to customers who want to use hotspot service. As well, the network should have wireless-client isolation enabled, so that customers who are using the hotspot cannot browse on to each others’ computers.

Previously, there wasn’t any wisdom in implementing link security on a public-use wireless network but now that most computers and handheld devices support WPA-based link security for wireless networks, adding this function to WPA-level is still worth it for achieving some control and security in a public-use wireless network.

It is still important to change the WPA-PSK passphrase regularly such as at least twice a month. Some environments may require the passphrase to the changed every week. This is so that it becomes hard to set up a “fake hotspot” using your service’s credentials or keep a computer logged in to the hotspot service without you knowing.

As well, your hotspot should properly support VPN pass-through for all protocols so that business users can log in to their workplace VPNs  without any headache.

Special hotspot-gateway devices

It may be worth knowing that if you want greater control over your public Internet service, it may be worth implementing a “docket-printer-based” wireless hotspot gateway like the Netcomm HS-1100, Solwise WAS-105R or Zyxel N4100.

Here, these devices direct users to a login page where they have to key in a session login and password that they transcribe from a paper docket that is printed from a docket printer attached to the hotspot gateway. If you intend to offer a paid service, these devices put you in a position to use the payment methods and paths that you use to accept payment for your goods and services.

This is unlike some other hotspot gateway setups that require the potential user to pay another company directly using their credit card or an account maintained by that other company using a payment form hosted by that hotspot. Typically, a lot of these setups are managed in a manner where you don’t have much control over how the service in provided and the service may be provided in a manner not dissimilar to how most vending and amusement machines are provided where you don’t own the equipment, representatives visit the premises to maintain the equipment and you get a small “cut” from the takings.

As well, the session login parameters that your users type in from these dockets exist only for a particular time limit. This is also important for people who run a paid service, but can be useful for managing complimentary service so you can be sure that the people who are using your service are your customers or guests who are in your public areas.

If you do run one of these dedicated hotspot gateway devices, such as a “docket-printer-based” device, the wireless network that these devices operate should still have WPA-PSK security with the passphrase changed regularly. The “docket-based” devices will list the WPA-PSK passphrase on that same docket so your customers can still log in to your hotspot from their device.

Branding options

If you do implement these devices, make sure that you know how to brand the customer-facing user interfaces.

Most of these devices can allow you to upload a graphic and integrate it in to the login interface or they can allow you to upload customised login screens or point to a Web server for the login interface graphics. The latter option may appeal to you if you have a good hand with creating basic HTML Web pages.

Here, make sure that you have your business name and logo and, if you can do it, set the colour scheme to your business’s colour scheme. As well, make sure that your business name appears on the access dockets that your hotspot gateway prints out.

Power outlets

With a hotspot, always expect that some of your customers will use the power outlets on your premises to power their laptops or smartphones from AC power to avoid compromising battery runtime. This is more so with customers are operating older equipment that has batteries that are “on their last legs” or are working VPN sessions in order to “pick up” files from work and want to be sure this is done properly.

Here, a few double outlets near the tables can work wonders here and if an outlet is used for powering a device like a lamp, the device could be connected to the outlet via a multi-socket power-board with extra outlet space for a few appliances.

Conclusion

Once you know how to choose and set up your public-use wireless network properly, you can make sure that this is a service that your customers and guests will benefit from fully. This may even put your business “on the map” as far as customer-service extras are concerned.

Introduction

Between the end of October and the beginning of November, I had a chance to interview people who work with two different companies that work in the consumer audio-video market and had noticed some trends concerning this market and its relevance to the online world.

One main trend was that there was increased focus by consumer-audio manufacturers who work in the popular marketplace on delivering DAB+ digital radio equipment rather than network-connected audio equipment to the Australian market. This may be because some of these firms need to see this technology become more popular here and want to have “every base covered”.

Sony

From my interview with Kate Winney I had observed that Sony had a strong presence in the connected-TV scene. Here, this was more concentrated with their newer “main-lounge-area” TVs but they are providing this functionality on some of their video peripherals, namely their BD-Live Blu-Ray players.

We agreed that Sony had no Internet radio in its product lineup although they implement Shoutcast on their high-end home-theatre receivers like the STR-DA5500ES. But we agreed that they need to make DAB+ available on their stationary “big sets” like hi-fi tuners, receivers, home-theatre-in-box systems and bookshelf audio systems. They are releasing a few DAB+ sets but most likely as stereo systems rather than as portables or components.

I had stressed to Kate about Sony implementing vTuner or a similar directory-driven service which is implemented in most Internet radios. This is because most of these services offer access to the simulcast streams of the government, commercial and community radio stations broadcasting to local countries around the world as well as the Internet-only streams of the kind that Shoutcast offers. It is also because most people who are interested in Internet radio are likely to want to use it as a way of enjoying the “local flavour” of another country that is provided by that country’s regular broadcasters rather than just looking for offbeat content.

Kate also reckoned that DAB+ digital radio needs to be available in the dashboard of cars in the new fleet, preferably as standard equipment or as a “deal-broker” option offered by car dealers for the technology to become popular. I was also thinking about whether Sony should offer DAB+ technology as part of the XPLOD aftermarket car-audio lineup.

Bush Australia

From my interview with Jacqueline Hickman, I had noticed that Bush are still focused on implementing DAB+ digital radio in Australia but are using Internet radio as a product differentiator for their high-end “new-look” sets that are to appeal to young users

Their market focus for consumer audio is on the “small sets” like table / clock radios, portable radios, small-form stereo systems but I have suggested implementing or trying some value-priced “big sets” as product ideas. This is even though they run some “main-lounge-area” TVs and digital-TV set-top boxes in their consumer video lineup.

The ideas I put forward are a DAB+ or DAB+ / Internet-radio tuner that is for use with existing audio equipment and a FM / DAB+ (or FM / DAB+ / Internet-radio) CD receiver with optional speakers. A market that I cited are the mature-aged people who own “classic hi-fi speakers” from 1960s-1980s that they like the look and sound of but may want to run them with a simpler cost-effective component. I had made a reference to the “casseivers” of the late 70s and early 80s which have an receiver and cassette deck in one housing and what these units offered. Jacqui had reckoned that companies like B&O and Bose filled the market but I have said that some of the companies have gone to active speakers rather than integrating power amplifiers in the equipment. As far as the DAB+ tuner is concerned, she suggested that a person could use a portable DAB+ set and connect it to the amplifier using an appropriate cable.

I raised the topic of IPTV but Jackie was not sure whether this will be implemented in any of their TV sets or set-top boxes at the moment. This sounds like a product class that hasn’t been properly defined with a particular standard and platform especially in this market.

Conclusion

It therefore seems to me that there is more interest by consumer-electronics companies in nurturing the DAB+ digital radio system and the DVB-T digital TV system because they are based on established technology and established metaphors; and appeal more to “Joe Six-Pack” than the Internet-based technologies.

Also, I had noticed that it takes a long time for all equipment classes to benefit from a new technology. This is more so with DAB+ digital radio and, to some extent, Internet radio where the mains-operated stationary “large sets” like hi-fi equipment and stereo systems are under-represented.

On Wednesday 3 November, I had been invited by Monique Haylen from Mint PR to have an interview with staff from Brother International at their offices in Macquarie Park. The staff members who I talked to were Heidi Webster (Brand and Marketing Manager, IT and Office Products) and Stephen Bennett (Pre-Sales Technical Support Specialist, Network Printing Solutions).

I raised some general findings and trends that I have observed in the industry since writing this site and they may be of interest to a company like Brother as they develop their products for use in a home or small-business network. One of the reasons I have put these findings forward to them is so they can make their products compete very well in a crowded marketplace.

A3 multifunction inkjet printers

After my review of the Brother MFC-6490CW A3 multifunction inkjet printer, I thought it might be a good time to delve deeply into the future developments of these MFCs.

This class of printer is selling well but is popular mainly with graphic design, CAD and engineering customers who appreciate working with this paper size for their plans and artwork. The architect customers especially appreciate the ability to scan and copy from A3 size mainly as part of submitting their building plans for government approval.

Brother wants to see these machines and the A3 page size used more in the general office space rather than just these vertical markets. The applications that we were talking of include printing up of large spreadsheets as well as using this large page size to turn out promotional material that impresses customers. Heidi even was thinking of the cafe that we were having coffee at and how a cafe or restaurant could print up menus and “specials” lists on this page size.

They intend to implement a survey program amongst the people who have bought the A3 multifunction printers in order to find out how the printers can be “taken further”.

They looked at the usefulness of A3 scanners in these machines but these would be of use primarily to the previously-mentioned vertical markets. They reckon that this function may not see much use in the general office space and may keep the A3 scanner as a product differentiator for some of their high-end models. But they have also said that there is still the desire amongst most users to enlarge material that was originally printed on A4 and print it on A3 paper.

IP-based faxing

I have raised the issue of Internet-based faxing and email-to-print applications but this appears to be a very difficult feature to implement for most small business and home users. This issue is becoming more real as we move towards IP-driven telephony setups like the UK’s 21CN project and Australia’s National Broadband Network that will play havoc with regular fax technology. This technology is designed for the circuit-based telephone setups like the “plain old telephone service” or GSM mobile telephony and Stephen said that businesses who have moved their telephony infrastructure from the orthodox analogue-based setups to all-digital setups have had lots of trouble with their fax systems after the conversion.

The current solution that Brother uses involves the use of T.37 technology which uses regular POP3/SMTP email setups with use of existing mailboxes but the task of setting this up isn’t simple for those of us who aren’t very computer-savvy. Heidi and Stephen raised the idea of implementing a “wizard-driven” setup experience to establish this functionality. They also raised the issue of the IP-based telephony projects providing support for T.38 Internet-fax protocols and I was also thinking of these projects implementing “bridge” setups to link existing fax machines and circuit-based phone networks to this packet-based technology.

The way that they will prepare for the IP-based faxing world would be to integrate PSTN and IP fax functionality in their SOHO and SME network printers when they provide fax functionality.

Implementation of HomePlug powerline networking technology

I have raised the issue of Brother implementing HomePlug powerline networking as a network connectivity method for their printers, like I would do with all the other printer manufacturers who offer network-enabled printers. This is in order to see this network-connectivity technology be considered as an additional or alternative “no-new-wires” connection method.

There is action on this idea in Japan but they will probably release it in to a subsequent generation of printers. Stephen has also raised the issue of connection reliability with Wi-Fi networks that he has encountered through his work, and this could become a valid idea.

I have also raised the possibility of printers that are connected to a wired network being a Wi-Fi access point as an optional function and they have accepted the idea. This includes the concept of a secondary or “infill” access point for difficult setups and I was citing old double-brick houses with extensions, multi-building setups.

Sewing machines being linked to the home network

As I know that Brother also have made and do make sewing machines and similar equipment, I have raised the possibility of integrating this kind of equipment with the home network. This is because, from my observations, most households are implementing home networks whether to provide Internet access to many computers and devices, or to provide wireless Internet access to a laptop computer that is moved around the house very easily. I was targeting this idea at the high-end computerised sewing / embroidery machines that allow a user to design embroidery patterns on their regular computer using manufacturer-supplied software and upload these patterns to the sewing machine so that it can start working on the pattern.

Most such machines directly connect to the host computer as a peripheral using a USB cable. But there are people who don’t want to have the computer, whether a desktop or a laptop unit, in their sewing room. Even if they do want the computer there, they would have to create room near the machine for the computer and this can be very difficult in the midst of a project with all that cloth, all those craft tools and other bits and pieces.

I told Heidi and Stephen about the Silex Stitch-Link device (http://www.silexamerica.com/support/other/stitchlink.html) that uses the USB-over-network technology to link sewing machines to PCs via the Wi-Fi network. Like other USB-over-network devices, this unit requires the user to install special software on their computer and make sure that their host computer “claims” the USB-over-network device in order to establish the link to the peripheral that is connected to the device.

They were interested in this idea especially as a way of endowing more functionality and features to the high-end class of machine. They also saw this on the premise of “if Brother can network-enable their printers, why can’t they network-enable these sewing machines”. I then put forward ideas like integrating Wi-Fi or HomePlug functionality or simply adding an Ethernet socket to the machine for use with an optional HomePlug kit or Wi-Fi client bridge or a simple Ethernet cable.

Conclusion

These issues are likely to help with placing Brother’s position in the home and small-business network for the main device classes that it specialises in.

This year is a very special year as far as one of the two annual “pillar” trade shows for consumer electronics is concerned. It is going to mark the 50th time the Internationaler Funkaustellung, the premier trade show for consumer-electronics in Europe, has been hosted.

What is the Internationaler Funkaustellung?

The Internationaler Funkaustellung, also known as the IFA, is a German trade show which was primarily centred on consumer entertainment electronics but is now also focusing on major and small appliances intended for personal or domestic use. It was initially a way for Germany to show its radio technology prowess when the medium was just to become a commercial reality.

This used to be an event held between August and September of every second year but is now held annually between the same months. It had existed since 1924 but was suspended through World War II as Germany focused its efforts on the war. It was initially hosted in Berlin but was hosted in different larger cities around Germany including West Berlin even when the nation and that city was divided.

Initially, this was used by German consumer-electronics manufacturers to promote their wares and Loewe, one of the German names associated with luxurious TV sets, has been with this show ever since it started.  As the consumer-electronics scene became more international, this trade fair became more international and also became larger.

An important step in the presentation of new technology

I have seen this show in the same league as the Consumer Electronics Show in the USA as being one to watch when it came to consumer electronics. Typically, this show would be where consumer-entertainment technologies that were relevant to Europe, Australia or New Zealand were premiered or commercialised.

Micro Hi-Fi component systems

Radio – TV – Tape Recording – Hi-Fi – Stereo Sound – FM stereo – Microgroove (LP / 45) records – Cassettes – Colour TV – Dolby NR – Teletext – Enhanced Radio Technologies (ARI traffic information priority, RDS with textual display of station metadata) Home Video – Compact Discs –Stereo TV, Hi-Fi Video and Home Theatre –  MiniDisc -  DVD – Digital Radio – Digital TV – Satellite Navigation – HDTV – 3DTV

You name it, it was either premiered or had its European commercial launch here

Teletext - a predecessor to interactive TV

Of course, this show gave other countries like the USA a look-see in to the consumer-electronics and broadcasting technologies that were in “full swing” in Germany but weren’t being launched or given a commercial chance in the home country. One example was Teletext which allowed TV stations to transmit textual information alongside their video signal, with the end-user being able to call up the information on to the screen of a suitably-equipped TV set using its remote control. Another example was the ARI traffic-information-priority technology where a suitably-equipped car radio could be set to play traffic announcements at a louder volume than the rest of the programme material or tune for only those stations that run the announcements regularly.

Now including domestic appliances and personal care

Since 2008, the organisers had decided to make the IFA show encompass domestic appliances as well as consumer electronics. It was initially a small area of the show but this class of goods increased in its share of the show’s floor space. This even led towards the effective amalgamation of a European home-appliance trade fair with this one in 2009 with this fair become the European universe of all consumer electronic and electrical devices. This trend hasn’t been reflected in the Consumer Electronics Show in the USA, mainly because of a trade-specific fair that covers this class of goods sold in that market or other market-specific reasons.

This was symbolic of a new trend with such appliances being not just a functional element in one’s life but a stronger part of one’s lifestyle. It also included the desire for consumers to buy the major appliances that are more resource efficient, especially as governments are using tax breaks, “scrappage” / “cash-for-clunkers” schemes and similar programs like to assist in this goal.

As well, the last financial crisis has encouraged an increase in “at-home” time and the industry is taking advantage of the fact by integrating small appliances like espresso machines as a way of mimicking the environment of being “out-and-about”.

Relevance to the home and small-business IT world

Over the last ten years, the home network has become an integral part of the consumer lifestyle, especially as “always-on” broadband Internet has become commonplace and the number of multiple-computer households increases. The IFA show has then become a showground for manufacturers to exhibit devices like broadband routers and network-infrastructure equipment as well as desktop and laptop home computers.

Infact, the Wi-Fi-equipped laptop computer and the Wi-Fi wireless home network has become more important over these years thanks in part to the Intel Centrino campaign which emphasised the laptop computer being part of one’s lifestyle. Similarly, mobile phones have become Internet-enabled multi-function devices that can work either with the cellular telephony infrastructure or with a Wi-Fi network. This concept has been spurred on by the recent crop of Nokia phones and the Apple iPhone.

As well, the arrival of file-based media playback, spurred on my MP3 digital audio players, has integrated the computer and the home network as an integral part of the home entertainment system. This functionality was initially in the form of separate devices but has ended up becoming another function of regular audio and video playback hardware and has been enhanced by the use of standards-based technologies like DLNA. Therefore most consumer-electronics firms are using this show to launch or exhibit product models or ranges that feature this ability. Similarly most computer companies are exhibiting network-attached-storage devices that can hold multimedia files and share them around the house.

This concept has extended in to the realm of Internet-based broadcasting where radio or TV content can be obtained live or on-demand from a content-provider’s Website. This has made consumer electronics companies and others work out ways to bring this content forward to TV sets and hi-fi systems without an intimidating and unwieldy device or user interface.

An interesting comparison

Conclusion

This is a way of celebrating how this show has become a “pillar” trade fair as far as consumer electronics and technology in the European market is concerned.

During mid-1995, the Intel-based “IBM-PC” desktop computing platform had been given a major improvement with the arrival of a new operating system from Microsoft. This operating system, initially known as “Chicago” and was to be known as “Windows 4” and “MS-DOS 7” but became known as Windows 95 had yielded many improvements to this platform that it was made increasingly legitimate as an “all-round” general-purpose computing platform that was ready for the Internet.

This operating system was launched with a huge campaign which revolved around the new “Start” button on the desktop and this was enforced with the use of the Rolling Stones smash-hit song “Start Me Up”. The visual element that was also used was the clouds in the sky symbolising a new operating environment for your computer.

How did Windows 95 improve the Intel-based “IBM PC platform”

Computer-Management Improvements

Integration of Windows graphical user interface with MS-DOS operating system

Previously, a computer that worked on the “IBM PC platform” required the use of Microsoft’s MS-DOS operating system or a similar operating system like Digital Research’s DR-DOS as its base operating system. These operating systems didn’t come with a graphical shell unless you paid extra for one and ran the shell as a distinct program.

This typically required users either to run a third-party menu program or graphical user-interface “shell” like Automenu, Microsoft Windows or one that was supplied with network software like Novell; or, if they had MS-DOS 4 or 5, start a DOSSHELL graphical user interface. IBM typically pushed their OS/2 graphical shell as one that was suitable for any of their PS/2 series computers.

Now, Windows 95 integrated the graphical user interface with the MS-DOS operating system and had this running as a default setup. It had led to avoiding the need to remember to run particular programs to use a graphical-user interface.

A lot less to run to add functionality to the computer.

Previously, if you wanted to run sound, advanced graphics or other multimedia, use peripherals like a mouse or a CD-ROM drive or use communications or computer networks, you had to make sure that you ran particular drivers or memory-resident programs. This typically required you to work with the CONFIG.SYS or AUTOEXEC.BAT files to make sure these programs start.

If you wanted to increase memory for particular programs, you had to know how to stop a particular memory-resident program to free up the memory space. In the case of communications, you had to use communications programs which were effectively “terminal emulators” to work with bulletin boards and these programs were the only ones that could control the modem. Similarly, if you ran a network, you would need to run networking software to allow the computer to benefit from the network. Some of these situations even required the location to have a resident “geek” called a system administrator to set up these computers. Even the Internet on a Windows machine behind a dialup modem needed the user to run programs like Trumpet Winsock to establish the connection.

This improvement alone allowed a small organisation to share files or printers between computers that are connected on a network with minimal configuration effort and has opened up the path towards the home network.

With Windows 95, most of these functions were simply handled by the operating system rather than by extra software that had to be started.  This had taken away all of the extra requirements that the user needed to think of to run a highly-capable computer and do what they wanted to do.

Ready for the Internet

1995 was the year that the Internet came to the mainstream. Cyber-cafes had sprung up around town and new businesses called “Internet Service Providers” came on the scene. It was considered the “in thing” to have an email address where you could receive Internet-based email and you also had to know how to surf the Web. The old order of bulletin boards and online services with their “controlled media” had fallen away for this new “uncontrolled media” order that the Internet offered.

Windows 95 was capable of working with the Internet “out of the box” whether through a network or a dial-up service. This was because the operating system had an integrated TCP/IP stack with support for PPP-based dial-up protocols. There was even a basic email client provided with the operating system.

User-interface improvements

The Start Menu

This was a new take on the previous DOSSHELL programs, Windows Program Manager and the third-party menu programs as being a place to find and start programs. Here, the user clicked on the Start button at the bottom left of the screen and found a tree of program names which would represent to software found on their system.

It had been considered easier for most users to start working on whatever they wanted to work on and has become a standard motif for all of the Microsoft operating environments since this operating system.

Windows Explorer and the object-driven view

The file-management functionality was handed over to Windows Explorer which provided for a new way of managing files and objects. It allowed for programmatic views like a “My Computer” view that provided for a simplified shell or an “Explorer” view with a directory tree in a pane as well as an object-driven file view.

This collection-viewing concept had extended to the Control Panel and other operating-system components that used collections as they were introduced in to the Windows platform.

Larger file names

Previously in MS-DOS, you were limited to an 8-character file name with a 3-character extension that was used for defining the file type. Now, since Windows 95, you could create a meaningful file name of up to 32 characters long which allowed you then to identify your files more easily. Thee was a special truncated 8-character version of the file name for use with older programs that didn’t support the new file-name convention.

It became more important as digital cameras became popular because people could name their photos in a way that reflects the content of the picture and also was important as file-based audio storage came on to the scene.

The Registry configuration-data store

Microsoft introduced the Registry configuration-data store as a way of avoiding the need to maintain multiple configuration files across the system. Here, this store allowed for a centralised point of reference for holding this data that the operating system and applications needed for configuration-reference information that had to be persistent across sessions.

Under-the-hood improvements

Integration with the 32-bit computing world

This operating system was built from the ground up to be a true 32-bit operating system that was tuned to work with the 32-bit processors that emerged since the Intel 80386DX processor. This would then allow software developers to compile their programs to run their best in a 32-bit computing environment.

This was in contrast to programs like Microsoft Word 6.0 which were compiled for Intel-architecture 32-bit processors but in a manner that was to be compatible with 16-bit processors of the same architecture. As well, most of the MS-DOS operating systems were also compiled for use with the 8-bit “PC/XT” environments and/or the 16-bit “PC/AT” environments. The operating-system limitation then didn’t allow these programs to work at their best even if run on a computer with a 32-bit processor.

This had allowed for a variety of optimised computing setups like true multitasking and multithreading that these newer processors could cater for.

It is like Windows 7 where the operating system has been tuned for a 64-bit computing world and optimised for the newer multicore processors that are part of the Intel-based processor architecture.

Readiness for newer computing designs

Windows 95 had also catered for newer computing design principles such as the “soft-off” principle that was part of portable laptop computers and was to be part of the up-and-coming ATX desktop-computer design standard.  This principle catered for “one-touch” power-off and modem-based / network-based power-on practices which allowed for improved system management for example.

The operating system also allowed for support of various forms of extensability through use of standards, class drivers and similar practices that avoid the need to overload Windows with drivers.

Conclusion

Windows 95 wasn’t just an “ugly duckling” of an operating system but a major turning point for the evolution of the Windows platform. Happy Birthday Windows 95!

Introduction

There may be a question that may come up when you build your new home or do renovations on an existing home. This question is whether to wire you premises for Ethernet or not and how to go about it?

What is involved when you wire for Ethernet

When you wire a house for Ethernet, you are providing a high-speed data backbone for your premises. This is achieved by laying Category 5 or Category 6 wiring from most rooms to a central location where there is a “switch” that moves data around the network at the appropriate speeds for the network devices.

The reason that it makes sense to consider the home-network issue, especially wired-in Ethernet, is because an increasing number of households are using two or more computers. Infact, there is an increasing trend for households to have more computers than TV sets. As well, computers can and have now become entertainment centres for bedrooms and other small areas thanks to DVD drives, sound-card setups and radio and TV-tuner kits that install in or connect to PCs. There is also an increasing common practice to copy CDs to the computer’s hard drive so that these computers double as personal jukeboxes, which is an asset with small areas. This means that there is a desire to have access to resources like the Internet and printers from all the computers that are in the house.

Similarly, there is new interest in the so-called “home theatre PC” where a computer is being used as a primary media center for the household. This is being achieved through the computer being housed in a case that is optimised for living-room use by having reduced operating-noise output and looking like a piece of home-entertainment equipment. These computers run an operating system that is optimised for viewing from a distance and optimised to do home-entertainment duties, plus being hooked up to the main living-room TV and sound system. This concept permits activities like the use of network media receivers as “media extenders” where one can “take” audio or video content to be viewed or listened to in other rooms.

If you have networked your computer equipment by using a “no-new-wires” method like wireless or HomePlug powerline; you may be dealing with a network that isn’t working at its best. This is because the “no-new-wires” technologies work on having the “no-new-wires” segment’s bandwidth shared by all the devices that connect to the segment. This is exemplified by poor response time during a network multiplayer game hosted across the “no-new-wires” segment or slow transfer speed whenever a file is being transferred between two nodes on the same segment.

Typically, when you implement a “no-new-wires” network, you would use a broadband router that connects to an Ethernet segment and the “no-new-wires” segment on the LAN side, like one of the many wireless Internet gateway devices. Also, if you decide to add on extra network devices, you would have to buy extra network bridges so these devices can work as part of the network.The possibility of high-speed Ethernet being available for home-computer users is made real through high-performance Ethernet network-connectivity devices being made affordable and ubiquitous for most users.

For example, there are Ethernet adaptors available for installation in PCI or ISA-based computers, or for quick connection to “sealed-box” computers via the USB port, or the PCMCIA or CompactFlash card slot. As well, allof the game consoles that are capable of online gaming have an Ethernet socket either built-in or as an extra-cost user-installed system accessory. Let’s not forget that most devices that connect to a network for some part of their functionality would have an Ethernet connector on board or on a supplied network adaptor module. Also, most newer computers are being supplied with built-in Ethernet connection abilities as a standard feature and people who build their own computers are now able to base their projects on Ethernet-equipped motherboards.

As well, the switches that are required as part of an Ethernet network are now available at very cheap prices. This all ends up with the Category 5 Ethernet medium being considered as a lowest-common-denominator for network connectivity.

Why wire a house for Ethernet?

You will benefit from the high data throughput that Ethernet provides in its current form – 100 Mbps, with 1 Gbps (1000 Mbps) being available now at a slight premium for new and existing small Ethernet networks. This will benefit applications like Internet gaming, network media streaming such as Internet radio; as well as graphics-rich printing.

You also gain the advantage of reliable network behaviour because you are not regularly sharing data transports that are prone to interference. This is due to the way the common Ethernet network switches provide dedicated bandwidth to each port on them. They also scale data throughput to the highest speed available between the client and the network switch that the client is connected to. If different clients are moving data at different speeds, the switch implements a buffer so slower clients can benefit from the data while the data is off the faster clients’ minds very quickly.

As you may have known before when you have worked with the computer network at work, or with your Internet experience, the Ethernet infrastructure can carry lots of different data.

This wiring practice will get the best out of the killer applications for these home networks i.e.

• Internet access from everywhere in the house;
• PC or console-based network / Internet gaming;
• Streamed media around the house using DLNA-compliant network-media equipment
• Voice-over-Internet-Protocol telephony which is either being provided as part of a “triple-play” service or an alternative low-cost telephony service

amongst other activities as outlined below.

IP-TV / Video-on-demand and the “Triple-Play” goal

There is increased interest in delivering video content over the Internet and being able to view it on the large-screen lounge-room TV.

This is being facilitated on two different grounds – one being to provide content complementary to or an extension of what is offered by broadcast TV providers and the other is for telecommunications companies and Internet providers to distribute multi-channel pay-TV via the same Internet “pipe” as the telephone service and broadband Internet service.

The first situation is to provide “over-the-top” video service where the Internet “pipe” is used by another operator to distribute streamed or downloaded video content independent of the broadcasters. It manifests in the form of “download-to-view” video-content services like Netflix, CASPA and Hulu or “complementary cable services” which provide channel groups that may not interest the main cable-TV providers, such as wholesome family entertainment or overseas / expat content in the US.  Increasingly, network-enabled video products like games consoles, TVs and BD-Live Blu-Ray players are now using apps or extensions that support broadcaster “catch-up TV”, complementary-TV or video-on-demand platforms.

The second situation comes to  “IP-TV” where TV signals are transmitted via an IP-based Internet-capable network. This method is being pitched as a way of using DSL or fibre-optic-based next-generation-broadband to distribute Pay-TV signals to subscribers. This has become more so with the ISPs and telcos moving towards offering “single-pipe triple-play” services with regular telephony, Internet service and multi-channel pay-TV from the same entry point. It involves the provision of a set-top box (STB) or personal video recorder which plugs in to the router via an Ethernet cable.

As far as this application is concerned, a house that is wired for Ethernet is at an advantage for the “IP-TV” service. It benefits security of the conditional-access system because it is harder to unnoticeably “sniff” out conditional-access key values before they reach the STB; and there is high quality of service due to the nature of “switched Ethernet” where high bandwidth and low-latency is assured for full-screen video. Also there is the ability to extend the service either through a “portable” setup where the STB is relocated at will or through having extra STBs connected to secondary TV sets, this being a feature increasingly offered as a value-added option.

Extending or improving the wireless network

Improving wireless-network coverage in older house

By wiring your house for Ethernet, you are also laying an infrastructure that can definitely work “hand-in-glove” with wireless networking.

This is whether you have your home network based on a wireless backbone provisioned by a wireless router or you are starting from scratch with a wired backbone. If you were on an existing wireless network, you could set up your “fixed” nodes like desktop PCs to work on the Ethernet system.

This then leads to the wireless network being primarily of benefit to those devices that gain the most benefit from it i.e. portable or transportable nodes like laptops, PDAs and Web tablets.

You are also in a better position to improve your wireless network’s performance by implementing a practice that is performed in corporate, education or public wireless networks. This is to install one or more extra access points in areas where it is not possible to gain optimum reception from your primary wireless access point or wireless router using your existing portable nodes. All these access points are connected to the one wired-Ethernet infrastructure and set to similar network parameters so that the wireless client devices can seamlessly move between these access points depending on which one has the best signal strength. This is illustrated in the diagram above this text and discussed further in my article on improving your wireless network’s coverage.

This situation would mainly affect most pre-1950s brick houses with thick brick walls because such walls can easily attenuate the short-wavelength radio signal that wireless networks use. In some of these houses that have been recently extended, the wall that joins the extension to the main house is often a very thick one because it used to be the outside wall, and therefore becomes the point of attenuation for the short-wavelength wireless-network radio signals. The same situation can affect houses with chimneys that are on interior walls that adjoin rooms. In these houses, especially where there is a fireplace or the remnants thereof in both adjoining rooms, these walls are noticeably thick in order to accommodate the chimney and this situation can lead to poor wireless-network performance. It can also affect buildings that are insulated with foil-reflective

This practice of using two or more access points would also permit optimum coverage of large houses by allowing one to deploy an access point close to each end of the house.

In the same manner, you can use HomePlug powerline  networking to complement the Ethernet network by catering to those devices that can only use this technology. This is done using a HomePlug-Ethernet bridge. This functionality may be built in to those routers that support HomePlug, as well as Ethernet and/or wireless as a LAN medium.

The reason this is going to be necessary in the long term because some manufacturers may decide to make network-capable devices that use an “existing-connection” method of providing network connectivity in order to save on design and manufacture costs. This is because they don’t have to add extra sockets on the device’s PCB for Ethernet or write in Ethernet-adaptor support into the device’s firmware. As far as the user or installer is concerned, there is no need to worry about making sure that there is an Ethernet connection accessible to the device or even connect another cable to that device.

Whether you have one computer or many on your premises; or whether you have broadband Internet or dial-up, the improvement brought about by wiring for Ethernet will be seen as enhancing capital value for your premises. This may certainly pay dividends whenever you sell the house or rent it out at a later date, because of the concept of pervasive broadband Internet becoming a reality. This brings with it a desire to wire up multiple computers to a network in order to share the high-speed Internet connection.

The Ethernet infrastructure has now existed on the same feature level as an intruder-alarm system as far as most customers are concerned when considering their next home.

The best time to wire for Ethernet

The best time to do this kind of work is whenever you are doing works that are involving the house’s electrical system. This would involve rebuilding; refurbishing or extending the building or rewiring the building to comply with modern electrical-safety codes.

This will mean that you may prefer to employ electrical contractors who are competent with telecom and data wiring. These tradesmen will advertise their competence by listing job types like telephones, networks, security and similar work in their advertisements and on their vehicles.

If you have a regular maintenance “sparkie” who does your repairs or other ad-hoc work, he may be able to do this kind of work or know of tradesmen who can do this kind of work on an ad-hoc basis.The reason is that this wiring can be done at the same time as the electrical wiring that is involved in the project.

It comes in to its own if there is “rough-wiring” being done before the walls are plastered or panelled; which is common during building work. Then you just need to have any fitting-off of sockets done when the walls have been covered and decorated.

If the job is essentially a re-wire job, the same electricians who do that job can pull the Ethernet cable through the walls while they lay the new AC wiring. By having the work done at the same time as any other major electrical work, you are in a position to gain maximum value out of your tradesmen who charge by the man-hour.

If you are installing an alarm system or doing similar work where new electrical infrastructure is being laid, you could have the Ethernet wiring laid at this point. This works best if the tradesman that you engage is competent at all facets of infrastructure work and will do this as part of the job.How to go about it

Central location

You will need to choose a location for the network switch, which is where all the data that passes the network goes through. It should be out of the way but easily accessible and shouldn’t be too hot.

The places that would come to mind are any built-in storage cupboards like the broom cupboard, the linen press or a built-in wardrobe in one of the bedrooms. You may use a place like the attic or basement. As I have seen for an alarm-system installation, you may use the wall hidden by the laundry door when it is open as a central location for the network switch. Ideally you shouldn’t use a room which is used for any heat-generating systems like hot water tanks, boilers or furnaces.

What to avoid when working out the Ethernet-switch location

If you are wiring an existing house for Ethernet and the premises is equipped with a security system, it is a good idea to locate this switch in the same area as this system’s central box. This means that if you decide to upgrade the alarm system to a more sophisticated security / home-automation “hub” that has a network interface, you can connect this unit to the home network cheaply and easily. In most cases, this kind of upgrade can be done with the same system peripherals (PIR and other sensors, siren, strobe light) all intact and able to work with the new system. You may also have to be sure that you have enough space near the system’s central box and room at the power outlet to plug in another “wall-wart” power supply so you can install the Ethernet switch without reliability problems for the network and the alarm system.

It also allows you to establish an installation point for any devices that provide “back-end” functionality for the home like network-attached-storage devices. It then means that you can service all these devices by going to one location.

The network switch

As for the switch, you should purchase a dual-speed (10/100 Mbps) unit with more ports than there are rooms to wire. This allows you to add extra network points at a later date or connect network devices like Ethernet-powerline bridges, wireless access points, network-attached storage or home-automation equipment directly to the switch.

There are many three-speed Gigabit Ethernet switches that are being sold at an extra per-port premium over the common 10/100 Ethernet switches. These would mainly appeal to those users who intend to work with high-bandwidth video or similar applications. They also have to work with network adaptors that are capable of working at the Gigabit speed, some of which are now under the $100 mark for a basic PCI unit. They are still worth considering if you want to have a future-proof high-speed Ethernet infrastructure.

It is also worth being aware of and considering switches that work as Power-Over-Ethernet power sources. These units use the Ethernet wiring to provide power to suitably equipped network devices thus eliminating the need to run a power wire to these devices. This feature would be a boon for wireless access points and network CCTV cameras because it removes the need to make sure that there is a power outlet near these devices or risk them being “down” due to accidental power disconnection.

Rooms to wire

When wiring up for Ethernet, it is a good idea to provide a point in each bedroom as well as the kitchen, living room, dining room / family room and the study or home office. This means that you have covered every primary activity area in your home, thus permitting you to install network devices in each of these areas.

You may not think of wiring the living room for Ethernet but this room is where you will end up using networked entertainment equipment. Such equipment could range from network media clients that either are connected to or are part of the TV and stereo to present digital photos, digital video clips and music files through these devices; through the popular online-ready games consoles like the PlayStation 3 and the Xbox 360, to dedicated media servers that present media that is stored on them over the home network. As mentioned earlier, an increasing number of affordably-priced desktop computers that are being sold by main-street computer stores are being designed to look like and behave like home-entertainment equipment, in order to be considered acceptable in rooms other than the study or kid’s bedroom. For example, you could easily think that a few of the newer home computers like the MSI MegaPC systems (Figure 2) resemble some of those bookshelf music systems that are sold at department stores and discount electrical stores.

Another reason would be that one may want to use a laptop computer in the living room during winter if there is an open fire, pot-belly stove or a radiant-style heater. This is because when these heat sources are in use, they become the focal point of the house.

If you use an open-plan shared-purpose room like the kitchen / family room or living room / dining room, it may be a good idea to have a network point in each logical “room”. This will avoid the untidy look and safety hazard (to person, machine and irreplaceable items) of running long cords across the floor of these rooms.

When choosing the socket type for the room sockets, it is best practice to use a standard wall-mount socket for each of these sockets. You may be tempted to use a side-entry socket, which is similar to some TV aerial points that are commonly used in Australia or the older Telecom Australia telephone connector. The problem with using a side-entry socket is that you may experience difficulty plugging and unplugging the device from the socket especially if the cable has the cheaper crimped-on connector.

If the job is aesthetically sensitive, you may be able to find outlet plates that work with the aesthetics of the room where the sockets are installed. This is easy due to the use of standard wall fitting designs that permit manufacturers to supply a large variety of trim-plates or socket modules. This can be of importance to anyone who owns a period home and wants to keep the fittings in tune with the home’s period.

Broadband Internet

You will usually the network-Internet “edge” router, whether it is an ADSL router or a broadband router connected to a cable modem or similar broadband-technology device, either in the study, the home office or the main lounge area and will most likely have Ethernet-enabled devices located close to it. Here, you would connect one of the router’s Ethernet ports to the Ethernet installation while having the other sockets available for the other Ethernet-enabled devices like a games console, network-attached storage or network printer.

Multiple Points in one room

In some rooms like the kitchen or home office, you will need to be able to have more than one point in that room. This is because you will often end up with multiple devices in that same room.

Extra ports on the main switch

This method involves running extra wires from that room to where the main switch is located and using one of the vacant ports on that main switch. This may allow direct bandwidth being provided to the device that is connected to the port; and can therefore yield better performance for that device. This method also certainly comes in handy when the devices are spread around the room because the room has multiple activity locations such as open-plan living areas.

It would be more fault-tolerant due to the removal of another Ethernet switch that could be a point of failure for the network devices in that room.

Regional switch

This method requires all the network devices to be plugged in to a switch, which is uplinked to the network point that is in that room. This mainly works better for any setups where the devices exist in a cluster; such as a home entertainment centre or a home office / study room.

The only main problem is that if the switch is powered down, those devices lose network connectivity. This can be worsened by the way that “wall-wart” power supplies are often used for powering most switches, routers and other network-infrastructure devices. What this means is that these bulky power supplies can easily fall out of most power boards which have outlets that are spaced wide enough for ordinary plugs rather than these “wall-warts”.

This can be alleviated if there is use of Power Over Ethernet, which uses the same Ethernet cables to run low-voltage DC power to network devices. This avoids the need for power outlets to exist near Ethernet ports for devices like access points. The power is placed into the network via a powered switch or a midspan power injector and devices take the power off the network cables either via their own sockets or through a power splitter which connects to the device’s Ethernet socket and power socket.

The Power-Over-Ethernet setup has been assisted via the use of the IEEE 802.3af standard, which now means interoperability between different device manufacturers. As far as switches are concerned, this could mean that you could have a network-powered 5-port switch with “power forwarding”. This means that the switch can be powered via a network port from a Power Over Ethernet infrastructure rather than a “wall-wart”; and feeds power through at least one of its ports to a network device that is powered over the network.

It can also be alleviated if the switch is powered off its own outlet, which would be the case if it is hidden in a built-in cupboard. This also avoids the temptation for one to unplug the switch in order to run other appliances, which can lead to that part of the network being unexplainably down.

Expandable solution for built-in devices

Expansion loop - current needs

One way to assure expandability for future network needs while saving costs on the current project is to create an “expansion loop” in areas where you may want to install built-in network devices. This could be easily done for an Ethernet point that covers the kitchen where you want to be able to install a built-in Internet terminal like the IceBox FlipScreen kitchen entertainment centre at a later date; while catering for existing needs. At the moment, these devices are equipped with an Ethernet socket as their broadband / network connection method. The same practice can also be done for rooms like the master bedroom or the living room where you think that you may add extra built-in network devices or network points at a later date.

By installing two Ethernet sockets in a cupboard such as the pantry or built-in wardrobe, you would achieve this ability to cater for this situation. One of the sockets is wired to a point that is in the main area, such as at the breakfast bar. The other is wired to the main Ethernet switch for the home network.

These sockets could be installed in a “three-gang” or “four-gang” faceplate with blanking panels on the unused panels. Then, in the meantime, a straight-through Ethernet patch cable is plugged into both sockets. This then means that you are able to connect any computers or other network devices to this socket that is in the main area.

When the time comes to add a built-in Internet terminal or similar network device, or add extra network sockets; you or an installer, runs a short run of Ethernet cable from the new device’s or new socket’s location to where the two Ethernet sockets are. Then, a socket is installed at the device’s location and another Ethernet socket is inserted in to the abovementioned multi-gang faceplate and these sockets are connected to the Ethernet cable run. You then use a 5-port switch to connect this device and the existing network socket to the existing network backbone. Here, the switch is uplinked to the main Ethernet switch while the existing Ethernet point and the new device are connected to other ports on the switch.

Expansion loop - satisfying a future networking need

This solution, which is illustrated in the two images here can also permit other “back-end” network devices such as security and home-automation “hubs” to be installed in this cupboard. As well, other network devices such as network hard drives and Ethernet-“no-new-wires” bridges can he installed in this location. It could even allow one to run extra Ethernet points in this same area at a later date.

Conclusion

Once you consider the idea of wiring for Ethernet, you would certainly have prepared your house for the connected home future. As mentioned before, this act of wiring for Ethernet will be even considered as a capital improvement, which may add value to your house in the Internet age.

You will also avoid the need to think about extra wiring chores should you think of implementing network-based home automation in the future, especially when most “connected-home” equipment will use a standard Ethernet connection on it.
