Shropshire proposes to run a rival full-fibre broadband service across its county territory

Article

Shropshire UK Moots Ultrafast FTTH Broadband Alternative to BT FTTC | ISPReview UK

My Comments

There has already been some action in the Home Counties when it comes to providing rural communities with full-fibre broadband courtesy of Gigaclear. But a proposal has been put up for another provider to provide a whole county in the UK with fibre-to-the-premises broadband with involvement from its local government.

The Shropshire County Counccil previously warned that they could ’t cover Shropshire with next generation broadband if they went the BT Openreach fibre-to-the-cabinet way which was based on VDSL2 for the copper run. But they have approached a rival provider to provide a “fibre-to-the-premises” service at a cheaper rate than the BT FTTC solution.

This would be inherently a public-private project with private investors where they could prove that they could even cover Shropshire’s rural properties with full-fibre technology. Readers who are in the USA or Australia may find this fanciful but the UK have rural properties that are relatively smaller than what is seen as common in these countries with a lot of small villages scattered around the country being the norm for the UK.

It will be initially a two-stage effort with a fibre-wireless effort with fixed-wireless technology in some areas but will evolve to a full-fibre technology in all areas. There is also the ability for a local village to pitch their own funding to go fibre all the way rather than a fixed wireless solution in Phase 1.

A good issue to raise with these community-focused developments assisted by other companies is whether they will give BT Openreach a “kick in the pants” to provide next-generation broadband at a more cost-effective price point. It also relate this to other markets like Australia, it could raise the issue of having competing providers working alongside local government to achieve the same goal.

As well, could this allow for the start of a competitive market when it comes to the provision of next-generation broadband in urban, peri-urban and rural areas.

Product Review – Acer Iconia Tab A500 Series 10" Android tablet

Introduction

I am reviewing the Acer Iconia Tab A500 Series 10” Android tablet computer. It, like most other Android-based 10” tablets, is faced off as a competitor to the Apple iPad tablet which is of the same size.

It is infact the first Android-based consumer/small-business tablet computer that I have reviewed for HomeNetworking01.info

The unit itself

Aesthetics and build quality

The Acer Iconia has a metal-feel about it which makes you think of a durable tablet computer. It is light in your hands but some people may find the smooth finish very slippery when they handle it.

Display

The Iconia’s display is as readable as most tablet computers go especially when you are using it for reading content. When you use the Android-provided touchscreen keyboard, you may not find the text entry procedure comfortable for long periods of content creation. As far as the display’s brightness is concerned, the Iconia Tab A500 is still bright enough for most users even if it runs on the energy-saving “dim mode”.

Of course, for video, the display had worked smoothly when handling YouTube and similar video playback applications

Audio

Acer Iconia Tab A500 left had side headphones and mini HDMI

Left Hand Side - Power switch, headphone jack, miniHDMI jack

Like most tablet computers, the Acer Iconia’s sound doesn’t have much in the way of volume output if you use the integrated speakers. Here, they would be good enough for audio prompts and the like.It was still clear for the basic local listening and you have the distinct stereo separation but I would recommend use of headphones or external speakers like Bluetooth A2DB audio setups.

Connectivity and Expandability

Right hand side - Power input, microUSB port and USB host port

All the units of the Iconia A500 Series have 2 regular USB device ports as well as a micro USB port for connection to a host computer. They all support Bluetooth connectivity for standard profiles as covered by Android. This includes the ability to do Bluetooth object-push file transfer as well as audio streaming with Bluetooth headsets and audio setups.

You can connect these devices to an HDTV using an miniHDMI-to-HDMI cable if you need the large TV screen.

Another USB port on this device - at the bottom of the unit, under the screen.

These Acer tablets have a feature that is common with most Android smartphones and tablets in that they have a microSDHC card slot. This means that you can expand on the storage that you initially bought or swap media collections around on different microSD cards as if you were working with cassettes or MiniDiscs.

The power connection is a 12 volt connection, which may make it easier to use the Iconia Tab in a car through the use of a cigar-lighter cord. This comes in handy when you load devices like the Iconia with movies or ebooks to be viewed by passengers on a long journey.

Performance

The Acer Iconia is very spritely when it comes to performance. For example, it was able to play sound from a DLNA network media server while I did some Web browsing without the sound deteriorating. It could also perform properly with YouTube even if you put the videos on full screen.

The battery can run for a few days of adhoc but regular mixed-activity use without charging. I haven’t yet worked out an activity plan to “stress-test” these devices for battery runtime.

Other factors

The Acer Iconia Tab A500 Series is equipped with two cameras, one of them being a front-facing one for videoconferencing. This would work well if Skype provided full videophone functionality across entire line of Android HoneyComb tablets.

Limitations and Points Of Improvement

One point of improvement that could come in handy would be to deliver Skype as part of the standard software mix for all of the models. As well, the Acre iconia, like most tablets could benefit from a detachable kickstand that comes as part fo the package. This could appeal to users who use a USB keyboard for typing up notes or those of us who push these units in to service as an Internet terminal / digital picture frame for the kitchen.

Conclusion

I would consider this Android tablet as a “floater” tablet computer as a multifunction general-purpose tablet computer where you value the large screen size and snappy performance. This is more so if you want a tablet computer that isn’t confined to Apple’s dream and you know what you are after for software.

The Wi-Fi-only units can be useful if you want to manage just one mobile broadband package by using your smartphone’s Wi-Fi tethering options to connect to broadband service on the go. You may go for the wireless-broadband-equipped units if you don’t mind running a separate wireless-broadband account and allowance for these devices.

Apologies for review-notes draft being posted too early

If you follow HomeNetworking01.info by RSS feeds, email or Facebook, you may have received a low-quality notes review
post for an Acer Iconia tablet computer. Sorry about this post appearing on this site.It was intended to be posted as a draft for continual editing so I can finish it on another computer and supply some photos of the Iconia Tab.

Look forward to a good-quality review of this Android-driven 10″ tablet.

First it was Armidale, now it is Kiama

Article

NBN switched on in Kiama, NSW | The Australian

My comments

This deployment of the National Broadband Network has become the second mainland location for this technology. The first mainland location to have the next-generation Internet was Armidale in NSW.

Kiama is primarily a tourist-attraction country town which attracts many day-trip tourists from Sydney. This then feeds a hospitality-driven economy centred around cafes and restaurants. Other than that, it doesn’t necessarily have a key employer like a corporation or university that could create a significant economy.

Of course, it is worth finding out which areas of these towns are actually wired up for the broadband service, especially if these towns are growing out or becoming major economic centres in their own right, as in the case of Armidale which has the University of New England as a key employer. Here, it could be feasible for certain suburbs or neighbourhoods to have the optical fibre pass every door, rather than the whole town. This is a practice that I have noticed with Australian pay-TV where certain communities had Foxtel cable pass their door while others didn’t.

It is also worth knowing, when one or two towns are established with the technology, it could then allow for infrastructure to be deployed out to neighbouring towns as it is built out, especially if “highway” runs are being constructed and “lit up” in order to connect major economic centres. This may also incite more key employers to set up shop in these towns thus creating an increase in the economy there.

Cynics would describe this effort as being political due to the towns being in marginal electorates and the provision of the National Broadband Network as a vote-catching exercise by the Australian Labor Party. But who knows how this could change if the NBN does change the economies in these towns such as through attraction of new employers.

It will therefore be interesting to see what comes about with the arrival of the NBN through the different towns and whether the fibre-to-the-home next-generation broadband would be a proper winner.

Windows 8–How it looks and operates is now defined

Windows 8 And Its Incredibly Cool New Touch Interface | Gizmodo.com

Windows 8 Gets A Radical Facelift And Touch Functionality (Videos) | eHomeUpgrade

Windows 8, iOS 6 set for tablet face-off in 2012 | CNET

My Comments

Basic comments about Windows 8’s touch screen user-interface

A key user-interface concept in the next version of Windows will be a “Start Screen” that looks like a cross between Windows Phone 7’s home screen and the Windows Media Center interface. Here, this dashboard will have “Live Tiles” which present always-updated information in the window panes.

The applications represented on the “Live Tiles” can be a fully-fledged Windows application or a HTML5/JavaScript “mobile-like” app that links to a Web resource. This is taken further with Internet Explorer 10 implementing this functionality.

There will be the full integrated support for tablet computers and similar devices with an interface that works best with these devices as well as a regular keyboard / mouse interface. One issue that may affect software developers is that they may have to work the software so it can behave properly with a “no-keyboard” interface as well as a “keyboard” interface. Of course, the touchscreen keyboard interface will support a split layout so that the user can work the keys with their thumbs.

For some programs that primarily use mouse interaction like strategy or puzzle games, there won’t need to be much work done on having the programs work between a keyboard interface or a touch interface. But on the other hand, programs that rely on text entry such as email, the program may have to work with remapping the user interface to permit use of the virtual keyboard interfaces.

But where could this all lead to when it comes to the design of Windows-based computers?

Ever since Windows allowed for “tablet-style” computing with the Windows XP Tablet PC Edition, where the computer is operated using a stylus rather than by touch, there have been two form factors put forward to the market. One was the “slate” form factor which is like the tablet computers such as the iPad, where there isn’t a keyboard but the computer could work with a USB-connected keyboard; and the other was a “convertible” notebook computer with a screen that swivelled 180 degrees and folded flat to become a stylus-operated PC. There have been a few touchscreen variants of these form factors released subsequently once Windows Vista provided the touchscreen interface option.

The “slate” or “tablet” form factor could exist as an alternative to the iPad and Android-based tablet computers; and they could allow for operation with small keyboards for word-processing and emailing. But the computer press have forgotten about the “convertible” notebook form factor which has seen some resurgence with some manufacturers running with “netvertibles” – netbooks that have a touchscreen which can swivel between a traditional layout and a tablet layout.

Windows 8 vs the Apple platforms.

Another article had raised issues about Windows 8 becoming a competitor for a subsequent version of Apple’s iOS platform, especially the iPad implementation.

But they also raised the spectre of it competing with the next version of MacOS X, known as “Lion”. The main factor about this is that Apple were viewing the MacOS platform as a “horizontal” platform and the iOS platform as a “vertical” platform; with scant mention of any touch-enabled Macintosh computers coming on the scene.

The possibility of a granular touch-based computer marketplace

What I would see with these touch-based operating systems is the ability for hardware manufacturers to provide a granular marketplace for touch-based computing devices. This means that there could be a touch-based computing device that could suit particular users’ needs and budgets.

It would range from the 7” coat-pocket tablets serving as an alternative to a dedicated ebook reader through 10” tablets like the iPad fulfilling most general-purpose “dedicated-tablet” needs to 13”-14” convertible notebooks appealing to those of us who do plenty of emailing, word-processing or similar work on the road.

Of course, the operating environments for units that are 10” or above will differ across the marketplace in a similar way to what is happening with the smartphones. Here, users may place emphasis on factors like software availability, operating-system flexibility, battery runtime and system performance as they choose the operating environment.

Conclusion

The proposed Windows 8 environment could then become a game change when it comes to the touch-based computing environment.

Buyer’s Guide – Buying a laptop or notebook computer

Introduction

I had previously posted a buyer’s guide about notebook and laptop computers but am providing an up-to-date version which reflects my experience with the notebook computers that I have reviewed over the last few months. It also will reflect what is part of the notebook-computer marketplace especially as the technology evolves and the cost of different specifications changes over time.

Notebook Computer Classes

Nowadays, it is becoming harder to place a notebook computer in a distinct class because of the fact that technologies are blurring these lines of division. For example, I am starting to see that most standard notebooks and desktop replacements and even the subnotebooks are appearing with 500Gb on the hard disk and 4Gb on the RAM. As well, I am seeing netbooks start to come with 250Gb on the hard disk through this year.

Netbook

Examples: Dell Inspiron Mini 10, HP Mini series, ASUS Eee series

HP Mini 210 netbook Dell Inspiron Mini 10 netbook

A netbook typically is of a small form factor, with a 10” widescreen display and works on a very low-end processor. It has a very low-capacity secondary-storage device like up to 160Gb or 250Gb for a hard disk or may use lower capacities with a solid-state storage device. The RAM memory will usually exist at 1GB at the maximum.

These machines are typically pitched as a secondary portable computer for people who do a lot of email or Web browsing “on the go” with a minimum of typing. They are also pitched for use in the home as an auxiliary computer such as in the kitchen or “Facebooking” in front of the TV.

Subnotebook / Ultraportable

Example: Dell Inspiron 13z, Apple MacBook Air series

A subnotebook or ultraportable computer is a larger computer that is typically designed for portable use and has a lot of emphasis on small size, thin profile and low weight. They may be optimised for long battery life.

Here, these computers will typically have a widescreen display of 13 to 14 inches and will have electronics optimised for low voltage operation. A lot of these machines may have a processor that has mainstream performance characteristics and will have a generous amount of primary RAM and secondary storage. The keyboard will still be large enough for you to comfortably type on and you may have a larger touchpad for navigating the screen. Some machines of this class may not have integrated optical drives and may not have high connectivity options such as a large number of USB sockets in order to allow for weight reduction.

Standard Notebook

Examples: Dell Studio 15, HP ProBook 4520, Sony VAIO E-Series, Apple MacBook Pro series

 Sony VAIO E-Series laptop  Dell Studio 15 Multimedia Laptop

The standard notebook computer is typically of large size and has average connectivity options. It will typically have a built-in optical drive, except some units that are built on a “thin-and-light” chassis. The screen will typically be a 15” widescreen type and these units will be built on a mainstream portable-use processor platform like the Intel Core platforms. An increasing number of these machines as well as the desktop replacements will be equipped with a full-width keyboard that has a separate numeric keypad so you can enter figures quickly.

Compaq Presario CQ42

There will be entry-level units like the Compaq Presario CQ42 which may be based on a processor platform like Intel Celeron and will have less memory, hard disk space and graphics performance than most of the standard notebooks. They will be pitched at students buying their first notebook computer or parents buying a notebook for their child who is starting senior school or university.

Desktop Replacement

A desktop-replacement notebook computer will be optimised for its role as an alternative to a desktop computer. It will have a large screen and have its processor, memory and hard disk space optimised for performance. It will rate highly with connectivity but will be very heavy and not rate well for battery runtime. Some machines may not even have a battery pack and will be sold as transportable computers or “desknotes”.

There are machines that will be optimised for multimedia activities like audio, video and photo editing and will have display and sound technology optimised for this activity. On the other hand, there will be gaming notebooks that are optimised for fast-response gaming “on the go”.

Product Positioning

Consumer

Examples: HP Compaq Presario laptops, Sony VAIO E-Series laptops

A laptop positioned at consumers will typically have a design that focuses on beauty and will be optimised for multimedia. They won’t have features that support reliability or security like fingerprint scanners, theft-recovery or data-encryption software or automatic hard-disk damage-limiters. In most cases, these units may be designed in a price-conscious manner because most consumers will end up buying on price alone.

There are exceptions to this rule where some manufacturers may try newer user-interface technologies on these computers or supply computers that are optimised for performance in the gaming or multimedia context.

Business

Examples: HP ProBook laptops, Dell Vostro laptops, Lenovo ThinkPad laptops

HP ProBook 4520 Series laptop

HP ProBook 4520 Series business laptop

Most machines made for this market are typically deployed by businesses, usually large businesses who buy a large fleet of these units for use by their staff during their tenure at the business. They have a different expectation to the consumer who buys a notebook for themselves.

A notebook positioned at the business end of the market will be optimised for reliability and security. For example, there will be various security technologies like fingerprint scanners or facial-recognition scanners built in to these machines. Manufacturers will also implement technologies like “free-fall” sensing on hard disks to safeguard data from being damaged by accident.

In most cases, there will be less emphasis on beauty or multimedia capabilities because the business market tends to adopt a more serious and conservative attitude towards machines that are “for the job”. This is although manufacturers like Dell are offering customisations for their computers that include different colour trims or improved multimedia capabilities.

Premium Models – the “Black-Label” end of the market

Examples: HP Envy series, Acer Ferrari series, ASUS Lamborghini series

HP Envy notebook computer

HP Envy 15 - an example of a premium notebook computer

An increasing number of laptop manufacturers are supplying at least one or more high-end laptop computer models that place emphasis on style and performance. The manufacturers will typically contract with a brand that is well-known for highly-desirable luxury goods to style the computer in the same image as goods associated with that brand, such as a Ferrari or Lamborghini “wet-dream” sports car. In some cases, other manufacturers, particularly those in the premium hi-fi or professional-recording scene, like B&O or Dr Dre’s “Beats” may contribute their technical know-how to a part of the computer’s functional design like its sound-reproduction capabilities.

These special computers will usually be pitched in a similar manner to luxury cars and are either for personal use or business use in a manner similar to how the company-funded executive’s car is used. Some of the machines in this class may not have the manageability and security functionality that a business notebook may have as standard but it may be worth knowing whether these feature are available as an option for that executive notebook that you are looking towards having.

These computers are worth their salt if you are considering using them for a significantly long time for both personal and / or business use but there should be a way of upgrading memory and hard-disk space on them or buying newer and better batteries later on down the track as you use them over the many years.

Questions

Do you intend to travel a lot; and how do you intend to travel?

If you do travel a lot, especially by public transport. you may have to give more focus towards portability. Here, you may have to consider either a netbook, ultraportable / subnotebooki or a “thin-and-light” standard notebook.

A netbook would be appropriate if you use it for ad-hoc emailing and other communications tasks but wouldn’t be suitable for long-term work. You would also gain better value out of it if you were using it as a computer that is supplementary to your main desktop or laptop computer.

An ultraportable or “thin-and-light” standard notebook may be more suitable if you intend to do a lot of work on this machine such as filing reports from the field. If you work with digital photos such as editing them, it may be worth looking towards a “thin-and-light” standard notebook for this work.

It is also worth investigating the possibility of opting-in higher-capacity batteries so you can obtain more run-time on the machine while you travel, especially by public transport. This is because not all public-transport options will provide access to ready power for charging.

Most standard laptops like the Dell Studio 15 may work well for those of you whose main travelling option is to pack the computer in to the boot (trunk) of your car. You won’t have to worry about carrying it around all of the time.

Do you use a desktop computer as your main computer?

You can place a lot of emphasis on portability and get away with lesser processor, RAM and hard-disk specifications if your are running a desktop computer or high-end laptop as your main computer. But you will need to make sure you have good network-connectivity options, preferably Ethernet as well as wireless so you can easily and quickly “check-out” data files from your main computer.

On the other hand, if you intend to use your notebook as your sole computing device, you should look towards performance, screen size, connectivity and hard-disk capacity as key deciding factors for your computer.  This also includes those people who prefer to buy a notebook computer over a desktop for their home computer because they have a small living space, prefer to stow it away when it’s not in use or want to move towards the “new computing environment”.

Application guidelines

These guidelines may sound too “pie in the sky” especially for small-business or consumer buyers who are used to buying the cheapest equipment available. But it is worth paying a bit extra for a machine that will cost less in the long run and have a long service life.

Student’s first notebook

If you are thinking of buying your child who is doing Year 11-12 (senior school / Form 5-6) secondary or tertiary (university, college (US) or TAFE) study their first laptop, you have to be sure not to short-change them. This advice may go against the commonly-accepted thought pattern of buying the cheapest laptop for a student because they may be more likely to damage the computer.

This class of students will use these computers for preparing their coursework that is part of their studies alongside online communications (email, social networks and instant messaging / Skype), games and multimedia such as being a jukebox for parties. They will be taking this machine between home, school / college and friends’ locations either by public transport, your car, a friend’s car or their first car which would most likely be a very old car which is likely to be very worn-out.

The processor, RAM and display subsystem are also of concern for all students, especially those whose work is graphically intensive, such as a design-based course or subjects that make heavy use of graphics or multimedia. This makes the machine more useable by the student because they don’t have to be waiting around for a task to complete on the computer.

The best choice for this class of user would be a standard notebook. Here, I would prefer for them to use a low-end business model, but with the highest-capacity hard disk that you can afford. The reason I would specify this is because the business models are pitched for reliability under the kind of abuse a student might dish at it such as frequent transporting, old cars with half-dead suspensions, perpetual party life and the like. I also specify the highest-capacity hard disk you can afford because there will have to be room for studies, digital pictures, MP3s and the like that will fill up the hard disk very quickly.

If cost is a real issue to you, you may find that refurbished or rebuilt ex-business computers may offer the right kind of value for this class of user. These would be available either online or through independent laptop specialists and these resellers would buy the older computers from large businesses or government departments who are upgrading their computer fleet on a regular basis or buy end-of-lease equipment from computer financiers. Then these dealers refurbish or rebuild the equipment before reselling it. With these deals, it may be worth finding out whether there are newer batteries available for these computers and / or whether they can upsize the hard disks in the computers to larger capacities. Similarly, you may have to raise the issue of whether you can buy an up-to-date version of the operating system and / or office software with the refurbished computer.

Blogger or journalist

This class of user will want to type wherever they are, such as when they are flying. They will also be needing to keep large amounts of data such as manuscripts or, nowadays, photos and video footage. As well, they need to be able to see the screen properly so they can edit their copy easily.

Here, a 13” ultraportable that can fit on the economy-class airline tray table, may work well for these users but they may have to investigate the possibility of buying extra power options like an “extra-power” battery when they do a lot of long-haul flights. In some cases, it may be worth looking towards a business-oriented ultraportable and use the security software on these units if they do a lot of controversial work such as reporting assignments in police states.

Work-home laptop for small business operator

If your laptop is going to be the “work-home”computer for your small business and you don’t have a computer at your small business, I would suggest a standard notebook or desktop-replacement computer. Here, these machines will have the performance that you need for your business life and enough storage capacity for your home and business life. Small-business users shouldn’t pass off the business-class notebooks and may find themselves benefiting from the features offered by this class of computer.

Moving towards the “new computing environment”

If you intend to move your home computing environment away from the desktop computer towards a laptop or notebook computer, it may be worth looking towards a computer which rates well on capacity and performance. This could lead to a mainstream consumer-rated standard notebook or low-end business notebook. Business users should move towards a mainstream business notebook if they want to move to the “new computing environment”.

On the other hand, if you want close-to-desktop functionality, it may be worth looking towards a mainstream business or multimedia notebook. Some of the premium-end computers could also suit this kind of user.

Secondary portable computer for a desktop user or regular notebook user

A 10” netbook could be useful as a secondary portable computer for emailing and other ad-hoc activities. On the other hand, if you do a lot of “typing up” on the go or do value a larger screen, you could go for a 13”-14” ultraportable computer because of its larger screen and keyboard. An alternative option may be a 14″-15″ low-specification standard notebook.  The hard-disk capacity may not matter much to this kind of use because you are likely to transfer the files from the secondary computer to the primary computer whenever you arrive at home or the office or transfer work-in-progress files to the secondary computer so you can work on them.

Here, you would have to make sure your secondary computer does well for connectivity especially as you are likely to connect it to your primary computer in order to transfer files. Here, you may have to make sure you have up-to-date networking requirements and at least a few USB ports so you can use memory keys as a backup measure.

Conclusion

The bottom line that you think of when buying that laptop computer is to factor what you are using it for and how you are using it so you can avoid shortchanging yourself by buying a unit that doesn’t meet your current needs or buying a machine that won’t see you through the long haul.

Preparing for next-generation broadband

In most countries, there is interest in setting up most of the densely-populated areas for a form of next-generation broadband Internet service. This will typically provide at least 10Mbps, if not 30Mbps or 100Mbps which will be more than double what your typical ADSL or cable broadband service will provide.

Key features that are being promoted alongside these services include the reliable streaming or downloading of high-definition TV content to many TV sets in the house as well as VoIP telephony, which will include FM-grade telephone conversations or reliable videophone conversations that are beyond the realm of science fiction. The VoIP telephony features will also work alongside remote-terminal setups and other telepresence setups to allow knowledge workers and management workers to work from home, thus eliminating the need to travel in order to commute to work.

One main issue that may affect your home network is making sure it is ready for the next-generation broadband service. This is by preparing the infrastructure for high-bandwidth data throughput and setting up a router that can work with the next-generation broadband technologies like VDSL2 or fibre-to-the-premises.

Upgrading your router to next-generation broadband

The next-generation broadband service will use different connection methods to what you are using now. This will either be fibre-to-the-home or VDSL2 via phone lines and will require a different kind of modem. In some cases, this modem may be provided by your “next-generation” Internet service provider as part of the deal or at extra cost. Some of these service providers may sell a broadhand router that has an integrated modem for the broadband connection as well as router functionality. There is also an increased likelihood for these devices to support VoIP analogue-telephony-adaptor functionality because these services will also be about VoIP telephony.

If you have an ADSL modem router, its ADSL functions will become redundant under this environment unless it has an Ethernet WAN (broadband) connection option. This function may be available in a few recently-issued high-end units either as an Ethernet socket that can be configured to be a LAN socket or WAN (Internet) socket; or as a dedicated Ethernet WAN socket.

When you buy your next Internet router for this technology, the WAN (Internet) side of the router should offer a Gigabit Ethernet connection so you can use it with fibre-to-the-premises setups where you have an “optical-network terminal” modem; fibre-to-the-curb or fibre-to-the-building setups that use Ethernet-to-the-customer copper-cable runs or other connection methods that use a Gigabit Ethernet socket. It may be worth keeping your eyes peeled for “dual-mode” DSL modem routers that work with ADSL setups or VDSL2 “next-generation” setups when you upgrade your ADSL router.

It also may be worth looking towards upgrading to a router which has 802.11n wireless and Gigabit Ethernet for LAN connectivity.  Preferably, the 802.11n wireless network should be a dual-band setup but it doesn’t have to be a dual-radio (simultaneous dual-band) setup, as I will explain later. This will allow for higher bandwidth that the next-generation broadband Internet applications will need.

As well, you may have to pay attention to how the router handles “quality-of-service” with VoIP and multimedia traffic. It is because this kind of traffic will become more prevalent on these high-bandwidth networks and other Internet use like checking on email, viewing Web sites or “download-to-disk” applications doesn’t impair the experience you have during a phone call or when you watch streamed Internet TV.

Your home network

Here, I am talking about upgrading your home or small-business local network to cope with the increased bandwidth that next-generation broadband will provide. This setup is based around the use of a Cat5 wired Ethernet segment that you may have implemented or may want to implement as part of a renovation job; a Wi-Fi wireless segment used primarily for laptops, smartphones and similar portable devices and a HomePlug powerline segment that you may use as a temporary or semi-permanent “no-new-wires” network segment.

The Cat5 Ethernet segment

If you have wired your home for Ethernet and used a regular Ethernet switch as the network’s “central” switch, now is the time to upgrade it to a Gigabit Ethernet switch. This will provide a high-speed path to devices that have Gigabit Ethernet connectivity and can provide “next-generation” speeds in to the home network. The old 10/100 switch can work well as a “spur” switch for a cluster of devices that don’t have Gigabit Ethernet connectivity.

Again, it may be worth looking for a switch that also supports “quality-of’-service” when you upgrade the existing unit. This is even though most of the Ethernet switches that support this are more expensive and require you to visit a Web interface to “fiddle with knobs” to achieve this goal because they are targeted at business users who have their network and Internet managed by dedicated staff or contractors. This may be rectified over the coming years with the implementation of “logo-mandatory” specifications and standards for seamless QoS management.

If you are working on building new premises, considering renovations on your existing premises or are even just planning to rewire your existing premises to current safety expectations, now is the time to consider wiring it for Ethernet. I have written a good article on this topic in the context of new renovations, extensions or rewiring projects. At least make sure you place an Ethernet socket near every TV-antenna (aerial) socket in the house so you can cater for IPTV which will be part of the next-generation broadband environment.

The Wi—Fi wireless segment

As part of the upgrade, a wise step would be to implement 802.11n Wi-Fi in your wireless-network segment. As I have explained in the article “Understanding 802.11n High-Bandwidth Wireless Networking”, there are different varieties of access points and routers for this technology.

One way to go about this while maintaining your regular 802.11g equipment would be to set up another extended-service set with a 5.4GHz single-band access point or a dual-band router set up on 5.4GHz. The existing 802.11g router could be put in to service as an access point running the existing extended-service set. You then focus computer equipment that is equipped with dual-band 802.11n Wi-Fi interfaces to the 5.4GHz 802.11n segment while equipment like smartphones, netbooks and Internet radios work on the 2.4GHz 802.11g network. The WPA security key can be the same for both Wi-Fi segments and you could have one SSID being described as <PRIMARY-SSID-54g> for the 5.4GHz segment and <PRIMARY-SSID> for the 2.4GHz 802.11g segment.

As well, the Wi-Fi equipment should support or implement WMM (Wireless Multimedia) quality-of-service “out-of-the-box” but most current equipment doesn’t support it. This is again due to uncoordinated quality-of-service signalling and quality-of-service not becoming a “logo-mandatory” requirement.

The HomePlug powerline segment

This network segment may need to be reviewed if it is going to be the primary wired carrier for all of the multimedia data that next-generation broadband Internet will deliver. This is more so if you are using a HomePlug link to provide content to a DLNA-compliant network-enabled TV set or IPTV set-top box.

Here, you would need to use a HomePlug AV segment for any multimedia applications, a temporary building-building link or as a “no-new-wires” wired backbone between access points in a multi-access-point 802.11n wireless network. This can coexist with your existing HomePlug 1.0 Turbo segment which can be used for applications like connecting Ethernet-enabled network printers to the network or maintaining a backbone for a multi-access-point 802.11g wireless network. As far as any HomePlug AV-Ethernet bridges go, you should prefer those units that have Gigabit Ethernet so as to provide proper throughput to the equipment.

The up-and-coming HomePlug AV2 standard, which allows for higher throughput, MIMO-based operation and each HomePlug AV2 device being a repeater, can allow HomePlug AV devices to become part of that segment.

Purchasing subsequent computer equipment

Any desktop or all-in-one computers or network-attached-storage equipment that you subsequently buy should support a Gigabit Ethernet connection. This issue may not be of concern if you buy relatively-new equipment but can be of concern with older secondhand desktop computers. These can be upgraded through the installation of a Gigabit Ethernet PCI or PCI-Express card in these computers, which requires at the most a small Phillips-head screwdriver to complete.

When you buy Wi-Fi-enabled equipment like laptop computers, you may need to look for equipment that has 802.11n technology. This may be a limitation if you intend to buy a secondary-use laptop or netbook which may not have this functionality or buy smartphones, Internet radios or similar devices that have integrated Wi-Fi functionality because most such devices stick to 802.11g technology to keep costs down or allow longer run-times when run on batteries. This could be worked around through the creation of a “compatibility-mode” 802.11n extended-service-set on the 2.4GHz band or establishment of an 802.11g extended-service-set with its own SSID for these devices to use.

The situation will be likely to change from this year onwards because of work being undertaken to build small-footprint low-power-requirement 802.11g/n chipsets that are optimised for battery-operated devices and manufacturers being interested in implementing the technology in their devices.

Conclusion

Once you know how to have your network ready for next-generation broadband by replacing devices that may slow down the data throughput, you are then able to take advantage of what this new technology offers.
