Achieving a failover printer setup in your business

Brother HL-2240D compact monochrome laser printer – an example of a workflow printer

I have come across situations with small offices such as clinics who run one or more dedicated laser printers that turns out receipts, invoices and other documents as part of the customer-facing business workflow. Some offices may run the printers also for some back-office requirements like preparing reports or balance sheets for that workstation.

But there is the situation where the printer can break down, usually with a mechanical failure like frequent paper jamming. This can happen more frequently as a machine ages and is worked hard in a busy office. It is analogous to that situation most of us experience when a car gets to that point in its life where it frequently lives at the mechanic’s workshop and drills a hole in your pocket because it is always breaking down.

This situation can impair the business’s workflow especially as one has to work out how to rectify a paper jam or, in some cases, reset the machine. As well, no woman would want to ruin their beautifully-done fingernails knocking them on the machine’s internals while removing jammed up paper.

In these situations, it is a good idea to set up a failover printing arrangement where you have other printers that come in to play if the workstation’s primary machine fails. This is easier to achieve if all of the printers accessible to the office or reception area are linked to the network.

For example, you could use a multifunction for this purpose even though each workstation computer has a dedicated laser printer like the Brother HL-2240D or Dell 1130n. The multifunction printer, which is often expected to serve as the main copier and fax machine for the organisation, could be a machine like the Brother MFC-8370DN or HP LaserJet M1536dnf for a monochrome variety or a Brother MFC-9460CDN or HP LaserJet Pro Color M475 Series for a colour variety. Even one of the high-end business inkjets like the HP OfficeJet Pro 8600 could do the job just as well.

Some environments that have two or more workstations may prefer to have one workflow printer per workstation. Here, it would be preferable to connect the printers via the network rather than directly to the workstation computers. Here this can allow the other workflow printer to be used as a failover measure.

But what you would have to do is to set up the workstations to use the printer that is local to them as well as this main multifunction printer or other workflow printer. This may be as simple as adding the driver set for the main printer to the computers or it may also require the line-of-business software to be set up to allow the use of two or more printers.

As far as default printers are concerned, you would have to set the primary dedicated printer as the default machine, then have the users select the main multifunction printer as a secondary printer whenever their primary printer fails. This can be done as part of ordering the print job in most software or going to the Printers option in the operating system and setting the multifunction printer as the default while the single-function workflow printer is out of action.

If you run a server-driven printing environment, it may be worth looking at options that allow failover printing so that print jobs that come from one workstation appear at particular printers in an order of availability.

Once you look at this option for setting up multiple printers in your office or reception area, you could then be sure of an arrangement where a printer failure doesn’t impede on your business workflow or affect how your business is perceived by the people your business benefits.

Toshiba to introduce the first NFC-capable Ultrabook

Article

Toshiba Satellite U925T is First NFC-Enabled Ultrabook#xtor=RSS-181#xtor=RSS-181#xtor=RSS-181

My Comments

From this article, I reckon that Toshiba has used the Satellite U925T Ultrabook to push themselves ahead of the game by integrating the “touch-and-go” near-field-communications technology in to a portable computer.

One key advantage that I see of this is exploiting the mobile-wallet systems like MasterCard PayPASS and, perhaps, Google Wallet to allow NFC-compliant payment cards to facilitate an online transaction that doesn’t have the fraud risks associated with “card not present” transactions. This would be facilitated by the use of appropriate software that interlinks with the NFC reader and merchant-side software that runs the transaction as if you are paying for the goods at a store using your card and their card terminal.

Similarly, the Android and Windows Phone ecosystem would benefit from this feature through access to the mobile wallets that can be hosted in the NFC-capable smartphones. This can extend to device-to-device file-transfer functions like Android Beam where users could upload pictures and sync contacts and QR-discovered Websites to the notebook from the smartphone.

In addition, the setup routines associated with commissioning Bluetooth or Wi-Fi wireless devices with this notebook can be simplified to a “touch-and-go” procedure if these devices support this functionality. This can then lead to the ability to transfer “extended-functionality” files to the host computer so as to open up advanced feature sets like sound-optimisation functions for headsets and microphones.

What I see about this more is that this Toshiba Windows 8 hybrid Ultrabook is an example of using NFC to demonstrate a synergy between open-platform computing devices. This then simply leads to a breeding ground for innovation.

Bluetooth Smart Ready product announcements piling up

Bluetooth Smart Ready product announcements piling up

My Comments

I have given some coverage about the new Bluetooth 4.0 “Smart” and “Smart Ready” technologies. These are improvements to the Bluetooth specification to allow the use of Bluetooth sensor and control devices that can work on low battery requirements – think 2-3 AA or AAA Duracells or a “watch” battery – for in an order of six months or more.

This has opened up paths for health and wellness devices like blood-pressure monitors, glucose monitors and pedometers. Even the old 80s-style digital watch is coming back with a vengeance as a smartphone accessory due to this technology.

Most of the Bluetooth-equipped tablets and smartphones issued over the past model year or so are equipped with this technology fully with software support. But an increasing number of newer laptops are equipped with Bluetooth 4.0 Smart Ready functionality at least on a hardware level and underpinned with OEM software. An example of this is the recently-reviewed Fujitsu LifeBook LH772 which has this interface.

These units would have full inherent implementation when they run Windows 8 and it could open up questions about how the Bluetooth 4.0 Smart technology could be relevant to the laptop or desktop “regular-computer” device class.

One way I would see it being relevant to this class is the availability of Bluetooth wireless keyboards, mice and game controllers that don’t need special rechargeable batteries to operate. Here, they could run for a long time of use on just the two or three AA batteries.

Sensor devices like temperature or humidity sensors that are important to particular profession or hobby groups like refrigeration / HVAC engineers or gardeners could benefit from this technology especially when used with a laptop or tablet. Here, these computers could work with data-logging software to record trends or monitor for abnormal conditions.

At least what is being proven with the current crop of Bluetooth-Smart-Ready capable regular and mobile computer devices is that the world of innovation with this low-power wireless netowrk is being opened up.

Asus’s latest USB laptop expansion module satisfies current expectations

ASUS Launches the New USB 3.0 HZ-1 Docking Station Based on DisplayLink’s Leading SuperSpeed™ Graphics Technology | BusinessWire

My comments

I have covered the concept of expansion modules a.k.a docking stations that connect to laptops via USB 3.0, Thunderbolt or other similar connectivity as a must-have accessory. This is to allow people who use smaller or less-equipped laptops like Ultrabooks to use other equipment like optical drives or larger displays at their normal workspaces yet be able to maintain the portability of these machines. I cited this kind of device when I reviewed the Sony VAIO Z Series ultraportable which came with one of these modules that housed a slot-load Blu-Ray optical drive.

Lenovo issued one of these USB 3.0 modules as the ThinkPad USB 3.0 Dock. This unit had a Gigabit Ethernet connection as well as an external sound module and self-powered USB 3.0 hub for five devices.

Now ASUS have issued an improved USB 3.0 variant of a USB docking station that they previously released. The previous iteration had USB 2.0 connectivity therefore having access to 10/100 Ethernet, VGA and DVI video as well as an audio module and USB self-powered-hub connectivity for four devices. The video is supplied to the module using the DisplayLink video-over-USB technology to transfer the video to the VGA and DVI ports.

Now this improved version satisfies the current expectations by being equipped with a Gigabit Ethernet port as well as an HDMI port for current displays. This has the audio module and the USB 3.0 hub but uses the latest iteration of the DisplayLink technology to exploit the high throughput of USB 3.0 for high-resolution displays and stereo or surround-sound audio via HDMI. It is infact the first USB 3.0 docking station or expansion module that I have heard of that implements this DisplayLink setup.

Personally, I would like to see this device and the previous version equipped with an SP/DIF optical output using the same 3.5mm optical-electrical jack that Sony used with some of their CD Walkmans in the mid-90s to facilitate digital CD-MiniDisc recording with their MD Walkmans. Here this connection could be used provide a high-quality PCM stereo or bitstream surround digital signal to amplifiers that have built-in digital-analogue conversion circuitry.

As long as these are kept to common standards, it could then be feasible to supply the expansion modules to work with extra peripherals at one’s main work locations.

Google-written YouTube client for the iPhone now available from the App Store

YouTube releases standalone app for iOS, tablet-tailored version in the works – Engadget

From the horse’s mouth

Introducing a new YouTube app for your iPhone and iPod Touch | The Official Google Blog

iTuned App Store Download link

My Comments

Apple are intending to remove the integrated YouTube player from iOS 6 as part of “stripping off” all things Google from the iOS platform. But Google have responded by developing a standalone player to be distributed through the iTunes App Store.

The version that is currently being premiered is pitched at iPhones and iPod Touch devices but Google are working on a “large-screen” version that is pitched at the iPad tablet.

There is an Integrated user interface for content discovery, where one can browse or search for videos. This includes access to the YouTube Channel Guide as well as an improved search-as-you-type engine. Even the ability to share YouTube videos through the “usual suspects” (Google+, Facebook, Twitter and email) has been improved.

The repertoire of videos avaliable to users with this YouTube client has increased, with users being able to view the Vevo music-video library like most of the clips that defined music video in the 1980s like this Dire Straits clip.

Of course, those of us who run iOS 5 on our Apple mobile devices could download this if we want the improved YouTube experience on the device. Also, this may provide a “coarse” user experience for the iPad until the iPad version is released.

Internationaler Funkaustellung 2012

IFA LogoThis year’s Internationaler Funkaustellung has been dominated by particular technologies. One was the TV and video class of devices showing some key trends such as displays being greater than 75” and the arrival of 21:9 ultra-wide displays as well as the start of a multi-vendor platform for smart TVs.

Another was the evolution of consumer and small-business computer equipment towards touch-enabled displays due to the arrival of Windows 8 with its touch-centric “Metro” dashboard-style user interface. Yet another trend was the open-frame mobile computing platforms i.e. Android and Windows Phone becoming popular amongst manufacturers and consumers, increasingly putting Apple on notice with their iOS mobile platform. In this environment, the lines of distinction between the classes of device are being blurred as we see the arrival of larger smartphones with 5”-6” screens and 10”-13” hybrid computers that become a tablet one moment and a small notebook computer with touchscreen the next.

I have given less space to the appliance sector in this report as the appliance market is primarily about the “durable” class of appliances expected to last in the order of seven to ten years and there isn’t much of an encouragement to allow customers to improve the appliances’ functionality through options that can be added on at a later stage.

Similarly, most manufacturers who launch camera equipment or printers for consumers or hobbyists would be waiting until Photokina in Cologne which occurs a few days after the end of IFA. This is where the photographic and cinematographic equipment activity across the consumer, hobbyist and professional sectors would be occurring.

Networked Home Entertainment

TV and Video

Three main trends that are showing at this year’s Internationaler Funkaustellung for TVs are the ultra-wide 21:9 displays, screen sizes of 75” and larger for a 16:9 display and 4K screens that have an ultra-high-definition display. LG were even running with an 84” LCD TV that used “Cinema 3D” technology that didn’t require the users to were 3D glasses.

Panasonic were running with 103” 3D plasma and 145” regular plasma TVs. This was while Samsung, LG and Sony ran with 75” and 84” LCD screens. LG’s set also had the new “Cinema 3D” glasses-free 3D vision technology. But Sony were also supplying a projector, a Blu-Ray player – the BDP-S790, as well as professional cameras as their way of creating an ecosystem for the 4K ultra-high-resolution system.

There was the launch of the Smart TV Alliance which LG and Philips (TP-Vision) formed to provide an open platform for the connected TV subsystem. Toshiba had signed up to this alliance along with support from Onigo, Mstar, Qualcomm and Yume system-on-chip vendors. This was also a chance to launch more apps for this platform.

Samsung also used this show to premiere their “transparent showcase displays” which were effectively see-through displays that could run video.

LG had used this show to launch their 21” Personal Smart TV which is the same size as most computer monitors and introduces the concept of the smart TV to the kitchen or the spare bedroom. This also has the Cinema 3D glasses-free 3D setup. As well, they launched the EA93 which is a 29” smart TV with the new ultra-wide 21:9 aspect ratio. They also demonstrated a 55” OLED TV which is 3D capable and brings to the large-screen TV the same kind of display that most HTC and Samsung smartphone users benefit from.

The Smart TV Alliance had been launched at this year’s IFA by LG and Philips. Here, Toshiba had joined the fold and a few system-on-chip vendors in the form of Onigo, Mstar, Qualcomm and Yume provided support to the platform. There also intend to be more apps launched by this alliance.

Network Audio

Denon’s latest package hi-fi system, in the form of the D-109, is network enabled and consists of the DRA-F109 stereo receiver (65watts per channel at 4 ohms impedance) as its hub and a CD player in the form of the DCD-F109. But this has an audio-focused network media adaptor in the form of the DNP-F109 which supports AirPlay and DLNA local network media playback and access to Internet radio and Last.FM. Both the CD player and the network media adaptor have walk-up connect-and-play for iOS devices and USB memory sticks via USB ports. You may be able to use it with the speakers you prefer or buy it with a pair of the SC-F109 2-way bass-reflex bookshelf speakers.

Sony is also running with the STR-DN1030 home theatre receiver which has integrated Wi-Fi and access to content via the home network. Similarly, the content can come via DLNA or AirPlay-enabled network sources or you could push the content from a mobile computing device or a laptop via a Bluetooth A2DP link.

But one main class of audio equipment that is showing through from a lot of the manufacturers at this year’s show are the speaker docks that aren’t necessarily designed just to work with the Apple iPod and iPhone. This is due to the popularity of the Android smartphones and the tablets. These either use Bluetooth A2DP connectivity or connect via the home network using AirPlay or DLNA network protocols. Most of these will have the Apple Docking connection for use with the current crop of iPods and iPhones.

Computing Trends

This year has become a key year for launching portable computing devices that can work in some cases as sole computing devices or mainly as secondary computing devices and it has been driven by the maturity of the Android platform and the launch of Windows 8.

Mobile Computing

The IFA, like other consumer electronics shows, bas become a huge presentation environment for open-frame mobile-computing devices like smartphones and tablets.

Samsung have use the IFA to premiere their technology including creating a special press event close to that show. Here, they launched the Galaxy Note 2 which is the second generation of their Galaxy Note phone-tablet bridge product. This one has improved processor abilities and runs the Android Jelly Bean operating system. It is styled like the Galaxy S3 and has an improved S-Pen stylus that is many years ahead of the 1990s-era PDAs. It is available as a 3G or 4G variant depending on the market.

Now Samsung has answered Nikon’s Android-based camera with their Galaxy Camera which uses Android and has the high-grade optics.

They also have released a multimedia player known as the YP-GP11 but better known as the Galaxy S WiFi 5.0 . This is again styled like the Galaxy S3 “iPhone-killer” and has a 5.8” screen. In my opinion, it could put the Apple iPod Touch “on notice”.

There is the Galaxy S Duos which is a dual-SIM variant of the Galaxy S2 and Samsung are also releasing an LTE-capable Galaxy S3 to the German market in October.

If Samsung has got some new Android hardware going, HTC is sure to answer them with a few prototypes. As well, Sony have run some more of the XPeria smartphones with one known as the XPeria Mint having a 13 megapixel camera and a 4.3” screen while powered by a 1.5GHz S4 processor. They also launched the XPeria TX which has a 4.55” screen, S4 processor, 1Gb RAM and 16Gb storage expandable by a microSD slot and driven by the Android Ice Cream Sandwich operating system.

Haier haven’t been quiet on the mobile-phone front with their Phone PAD 511 which is another Android Ice Cream Sandwich smartphone that has a 5.3” screen. They also fielded the Pad 711 “coat-pocket” and 1012 tabletop tablets that again run Android Ice Cream Sandwich,

Regular readers have noticed me review the Lenovo ThinkPad Tablet 10” “business” Android 3.0 tablet but Lenovo have released two tablets to this show. One is the IdeaTab S2 110 which is a 10” hybrid answer to the ASUS Transformer Prime. This one runs Android ICS and Bluetooth 4.0 Smart Ready but is available with 4G wireless broadband. They also released the IdeaTab A2107 which is an Android ICS “coat-pocket” tablet that is equipped with 3G, Bluetooth 4, FM radio and WiFi. Toshiba also fielded a 10” Android ICS Tegra-3-powered tablet in the form of the AT300.

As for accessories, there was the Tivitzen Pico Galaxy DVB-T tuner for Android mobile devices. This device is directly connected to the host via its microUSB, and works with the Tivitzen app to bring through broadcast TV to the phone or tablet.

Regular home computers

Due to Windows 8 being “released to the manufacturers”, every computer name was running computers that make best use of this operating system. One form factor that was very common was the “hybrid” tablet-laptop computer. These had the computing power, touchscreen display, primary and secondary storage in one battery-powered unit which could be clipped to a keyboard which, in some cases, had extra battery power for the computer, just like the ASUS Eee Pad Transformer Prime which defined this form factor. These could be set up to become a Windows 8 tablet one moment or a fully-fledged clamshell notebook computer with a proper keyboard at another moment.

A few examples of this class included the Samsung Series 5 which uses the S-Pen stylus and is driven by Intel x86 microarchitecture.

There were also some “convertible” notebook computers that could be folded to become a tablet one moment or a classic notebook computer. These converted by one pulling out the keyboard from under the tablet or swivelling the screen horizontally in a frame rather than swivelling the screen vertically. Toshiba and Sony fielded two examples in the former “pull-out keyboard” type with the Sony VAIO Duo 11.

Of course, most of the portable units were of the “ultrabook” form-factor, typically thin and light, being equipped with up to 256Gb solid-state storage as the main secondary storage and perhaps having an SD card reader for removable storage.

Toshiba’s example of this was the Portege Z930 successor to the Z830 that I previously reviewed. This came in two configurations – one being equipped with an i5 processor, 4G RAM and 128 solid-state storage while the other cam with an i7 higher-speed processor and increased RAM (8G) and solid-state storage space (256Gb). Toshiba had run the Satellite U945 14” low-end model as well as the Satellite P845t that capitalises on Windows 8’s touch abilities.There was also a Satellite S955 “thin-and-light” laptop in the mix as well.

Acer’s latest Ultrabook example is the Aspire S7 which comes in an 11” or 13” variety and both of these have Ivy Bridge processors, 4Gb RAM and 256Gb solid-state storage.

Sony was launching the VAIO Duo 11 hybrid portable computer which has an 11” touch screen, and slides out from tablet mode to be a laptop. It is also equipped with front and rear cameras, Wi-Fi, Bluetooth, NFC like Android Beam and has the essential stylus support.

Some of the computers even used the new 21:9 ultra-wide display with the Toshiba Satellite U840W having a 14” display of this ratio and 6Gb on the RAM and 500Gb hard disk / 32Gb solid-state secondary storage. This would be having the same height as the regular 13” Ultrabook but being wider. But Samsung had also released a Series 9 13-inch ultraportable with a “Retina-like” ultra-high-resolution (2560×1440) screen. Similarly, every manufacturer ran a series of touch-enabled all-in-one desktop computers that capitalised on the touchscreen user-experience that Windows 8 provided. Examples of these include the Acer Aspire 5600U / 7600U all-in-one lineup.

Dell were running a lineup of XPS touchscreen-enabled hybrid computers with the XPS 10 being a 10” Windows 8RT hybrid that uses ARM microarchitecture. This is in addition to the XPS Duo 12 which is a 12” hybrid that works with Intel architecture and runs Windows 8. They were also using this event to launch an XPS touchscreen all-in-one desktop similar to the Sony VAIO J Series that I reviewed previously.

One of the new computers that HP were launching to capitalise on Windows 8 was the Envy X2 hybrid which has a detachable keyboard.

Networking

There hasn’t been much on network infrastructure hardware for the home because most of this would have been launched at CEBit in March.

But Devolo had launched the dLAN LiveCam which is an IP surveillance camera that connects directly to a HomePlug AV network segment. This would yield increased video reliability due to the nature of HomePlug AV network technology.

As well, Toshiba had launched their first home-network NAS in the form of the Canvio Personal Cloud. As expected for the consumer NAS that is on the market, it would be able to work with dedicated iOS and Android apps so one can transfer data to and from a tablet or smartphone.

Conclusion

What I see of the Internationaler Funkaustellung 2012 is a focus on consumer / small-business portable computing for mobile and regular operating platforms; and the development of larger and wider displays which use a high pixel density that makes images look closer to a classic photograph.

Gigabit broadband now in Appleton, Oxfordshire

Two large Oxfordshire villages now to have fibre-optic broadband

From the horse’s mouth

Website for Appleton & Eaton deployment

My Comments

Previously, at the end of May 2012, I wrote an article about action taking place by Gigaclear to wire up Appleton and Eaton in Oxfordshire for real next-generation broadband.

Now the setup is in full flight and Gigaclear were running a demonstration about the idea of Gigabit next-generation broadband in these villages at the Appleton Village Hall to prove to Appleton & Eaton residents what this is all about. Here, they demonstrated the high-speed broadband service and what it can offer including VoIP, IPTV and similar services.

They will install the services to the property boundary but it will cost GBP£100 for 50m of drop fibre and a fibre modem-router. Here, the cabling will be installed by the owner or a separately contracted third party like www.boxcomngn.net who charge £85 for up to 25m. On the other hand, Gigaclear could do the job for up to £500 for a 50m run.

The service, which supports future-proof IPv6 dual-stack will typically cost £37 / month for 10Mbps reserved to £195 / month for 100Mbps. It includes use of 1000Mbps burst bandwidth and is sold in a similar manner to how most interconnect and hosting bandwidth is sold, and, to some extent some business Internet service are sold. It may seem expensive but there isn’t a requirement to maintain a PSTN line with British Telecom for an Internet service to exist.

The villagers can sign up to VoIP as a telephone replacement if they are happy with no battery backup if power is out. As well, there is the option to sign up with various IPTV services. Even Vodafone had offered a “Sure Signal” femtocell service for their subscribers so that they can get proper mobile telephony in to their properties.

This is another example where the small villages in the UK are being made aware of the idea of real broadband and what it can offer. It is also a good chance for villagers with larger properties to have a look at the feature articles so they can gain the best out of the new Internet benefit.

UPDATE:

Householders can use a UPS like the APC BackUPS ES series units (Amazon UK) or the Zigor Ebro 650 UPS (Amazon UK) to power the router, modem, analogue telephone module and DECT base so they can keep a lifeline VoIP service for this Gigabit fibre-optic broadband service.

A pressure-sensitive Bluetooth 4.0 Stylus to turn the iPad in to a digitizer

Pressure-Sensitive Bluetooth 4.0 Stylus Coming to iPad#xtor=RSS-181#xtor=RSS-181#xtor=RSS-181#xtor=RSS-181

My Comments

The Bluetooth 4.0 Smart Ready ability that the Apple iPad has now is being considered of use. Here, Ten One Design have introduced a pressure-sensitive stylus that works with this touchscreen tablet and turns it in to a digitizer. This has the ability to increase the thickness and darkness of a line as you add pressure to the stylus in a similar vein to the real pen or pencil

Six of the iOS drawing apps provide inherent support for this stylus with more on the way. Here, the developers would have to integrate the functionality for this device in their software to have it work. As well, it would require you to work with the files being held on your iPad.

But, with appropriate bridging apps for the iOS platform and the MacOS X and Windows regular computing platforms, this could make it feasible for an iPad that is tethered to a regular computer to become an improved version of one of those “digitizers” or “graphics tablets”. These devices had a tablet surface and a stylus so you could trace hand-drawn graphics or do freehand drawing in to a graphics program. In some cases, these tablets also were a command surface for some CAD programs where you entered drawing commands by “picking” them using the stylus.

Here, the combination of an always-updatable touchscreen display could allow for a variety of options for this class of work. For example, it could permit the direct edit of work on the iPad while using the main screen as an overview display. This could include freehand digitizing and drawing with the iPad providing a natural “paper” feedback and the work appearing on the graphics program.

Similarly, a CAD / CAM program could benefit from turning the iPad in to a “tabbed” command tablet with the stylus being used to “pick” the commands.

Here, the idea of a Bluetooth stylus or, in some cases, a “puck” could make the iOS or Android tablet earn its keep in the CAD or graphics-design office rather than just as a tool for media consumption.

Pioneer adds another network-capable device to the DJ table in the form of a CDJ

My Comments

Previously I wrote an article about the Pioneer XDJ-AERO bringing the Wi-Fi network to the DJ table so DJs can link laptops or mobile devices to their performance equipment and bring in the music on these devices as part of their set.

This time, Pioneer has taken this concept further with their CDJ-2000nexus, which is the first “CDJ” to implement network content delivery in a similar vein to the XDJ-AERO DJ console. This requires use of the rekordbox software on the regular or mobile computer to link the CDJ to the content held on the computer.

But, unlike the XDJ-AERO, the CDJ-2000 Nexus has the Ethernet port as its network connectivity option. Here, you could connect two or four of these decks to the LAN ports of a typical wireless router which is pressed in to service as an access point for the mobile devices, the ultra-cool MacBook AIr or other Wi-Fi only devices. Of course, you could connect laptops that have the Ethernet connection to these decks directly if it is just one unit or via an Ethernet switch if you have two or more.

This then leads to various functions and tricks which help with concurrent multi-deck work and, to that extent, there is even the ability to work parts of the same piece across the multiple interlinked decks.

Of course, the Pioneer CDJ-2000 Nexus can work with content held on the USB Mass-Storage devices, SD cards as well as regular or file-based CDs.

As far as I am concerned, it will be interesting to see what else will make the DJ table or booth require its own small network. For that matter, I would recommend that nightclubs who are designing or refurbishing their DJ booth as part of any capital works be encouraged to implement a small network for this area. As well, a surplus wireless router could end up becoming part of the kit a DJ transports with them in their van when they show up at their mobile gigs.

Feature Article–Extending your wireless network’s coverage

This is an update of the article originally published on 11 August 2008 and has been refreshed to encompass newer technologies and equipment features that wireless-network equipment have.

Many of you who have viewed this blog have been looking for information about extending the wireless segment of your home network. Typically it may be to cover a large house or to gain wireless coverage past a radio obstacle like thick brick or stone walls, foil-lined insulation or double-glazing which uses metal-based heat reflection techniques. Previously, I have mentioned about using this technique to mitigate microwave-oven interference on the 2.4GHz band which 802.11g works on.

Most wireless-network equipment manufacturers have released repeater devices that catch the existing wireless-network signal and expose it in to the new area. Some of these setups work on a vendor-specific manner or may work according to standard WDS bridging techniques. But they all require the use of equipment compatible with each other, usually equipment supplied by the same vendor.

Other companies have released “wireless range extenders” which create a new wireless-network segment using a new SSID but bridge it to the existing wireless segment. This can be a point of confusion as you have to determine the best SSID to connect to at your client equipment and you don’t necessarily get the full bandwidth from your home network in this newly-created segment.

The “extended service set”

The method that I am going to talk about here is the establishment of an “extended service set” comprising of multiple access points serving the same network and using the same SSID and security parameters. All the access points have to be connected to a common wired-network backbone which is part of the same logical network; and the access points must be working on the same technology – the same 802.11 variation and operating mode (G-only, N-only, mixed mode, etc).

This method can be performed with access points or wireless routers supplied by different vendors, thus permitting the use of equipment which is suited for the job at hand. It can allow for use of surplus routers simply as access points as long as they are configured correctly.

This setup won’t work properly across networks that are set up as multiple subnets or logical networks. An example of this may include extending a wireless network between two business premises across the street or corridor where they are served by separate Internet services. If you do want to link the two different premises across the street or corridor, you may have to make sure there is a wired or dedicated wireless backbone connecting both these locations before you set up this kind of network.

The diagram below shows what a small network should be like when running an extended service set.

Connection diagram for the multiple-access-point wireless netwrok

Key Components

The network backbone

The wired-network backbone can work on any wired-network media such as a Cat5 Ethernet, HomePlug power-line, fibre-optic LAN, MoCA TV-aerial coax, HomePNA phone-line or a mix of these technologies bridged to each other. It can even work with a dedicated inter-building wireless backbone that may be used for larger properties or to join shops or offices that are separated by a street.

The network backbone can handle other network traffic from wired-network devices like servers, desktop computers and games consoles; and become the network’s local data path to the Internet. This is while it works as the backbone for the wireless “extended service set”.

You may have be lucky to have an Ethernet cable in your house if you had it “wired for data”. But most houses typically wouldn’t have this facility everywhere. The other technology that I have found to do this job equally well is HomePlug AV powerline networking which works over the cable infrastructure used to provide AC power to your lights and appliances. It can reach further than the existing building, which is a boon if you need to extend coverage to garages, sheds, cabins or other outbuildings or have Internet access in a caravan or campervan used as a “sleepout” or mobile office.

Access Points

These devices are the transmitters that bring the data from the wired network backbone to the wireless client devices and make up the extended service set.

You typically will have one such device in the form of your wireless router which is at your network’s Internet-network “edge”. The wired-network backbone used as part of this “extended service set” would be connected to one of the LAN ports on this device. If you use a wireless router with one Ethernet port for the LAN and that port is used for a desktop computer or similar wired-network device, you will need to expand the number of sockets by using an Ethernet switch. These will typically be a “dime a dozen” for a five-port or eight-port unit. There are also some HomePlug-Ethernet bridges that have a built-in four-port switch that are worth considering if you are setting up a HomePlug backbone.

Repurposing the old wireless router

If you upgraded your wireless router to a newer model, you will still have your existing router gathering dust. Similarly, you may have changed broadband technologies like moving from cable to DSL or from DSL to a next-generation broadband technology and your router’s Internet connection may have been served by a technology-specific internal modem or connection.

This router that became surplus to your needs can work as an access point but will need to be configured appropriately.

Here, you will need to disable the following functions:

  • DHCP server
  • UPnP Internet Gateway Device functionality (typically referred to as UPnP)
  • Dynamic DNS functionality (if used)

As well, you will need to set the LAN IP address to something that is within your network’s IP address range but preferably out of the address pool used by the current router. The reason you have to take care of this setup is because there needs to be only one device performing “network-Internet edge” functions such as DHCP in a network and this device should be the one at the logical network-Internet border.

Some of the newer routers that are sold through retail have an “access point mode” option in their setup Web page. This make the effort of setting them up to run purely as an access point a simpler task because it disables the DHCP, Dynamic DNS and other functions associated with an “edge” router at the click of an option.

When you connect this router to the wired backbone, you use any of the LAN ports to connect the backbone. Never use the WAN port on this router for the wired backbone. This may not be an issue if the router you are setting up is a modem-router where the modem is performing WAN functions or you are using a router that has the above-mentioned “access-point mode” and this mode makes the WAN port become a LAN port.

“3-in-1″ HomePlug wireless access points

There is an increasing number of wireless access points that work with a HomePlug or Ethernet backbone. These devices, such as the Netcomm NP290W / Solwise PL-85PEW and the Devolo dLAN Wireless Extender, are as big as a compact “wall-wart” power adaptor used to power most electronic devices from the mains and plug directly in to the power outlet. They bridge between a Wi-Fi wireless segment (as an access point or wireless client bridge in some cases), a HomePlug powerline segment and a Cat5 Ethernet segment.

These units come in handy if you need to extend a wireless network on a temporary basis or simply if a compact device can do the job better than a large access point. They would come in to their own when you are using the extension access point to mitigate microwave-oven interference in the kitchen or if you want to extend the home network to a static caravan where the teenage kids can use that iPhone or iPad.

But with these devices, you have to make sure that you use one of the wired technologies as the backbone. This means that you have to use them with your HomePlug setgment as the backbone and the Ethernet connection to link a device like a desktop computer, PlayStation 3 or a network printer to the home network; or connect to an existing Ethernet backbone and have the device create a new HomePlug segment as well as working as an access point.

Setting Up The Network

Configuring the access points

You will need to know the SSID and the WEP or WPA wireless security parameters that are operational for your network. These are the only factors that need to be common amongst all of the access points of the network. The reason that the SSID and security parameters are set to the same details is so that wireless client devices can roam between the different access points without any user intervention.

The radio channels for each of the access points have to be set differently to each other. It is a good idea to set the access point closest to the kitchen to Channel 1 if you have a microwave oven in that kitchen. This is because, from my research, most of the domestic-market microwave ovens work at 2450 MHz which is between Channels 8 and 9 on the 802.11g channel list. I had tried an experiment to see whether a microwave can upset a wireless-network “cell” that is tuned away from its operating frequency.

If the access points or wireless routers is a consumer model that was made in the last few years, they would be equipped with WPS push-button setup. Here, you would have to make sure that they don’t reconfigure the wireless access-point parameters when you invoke the WPS push-button setup function. There is usually a “Keep settings” option associated with the WPS setup menu/

This option will then allow you to use the push-button setup on the nearest access point to enroll your wireless client device to your home network.

Dual-band wireless networks

If you are operating a dual-band wireless network which works on 2.4GHz and 5GHz, you may have to create separate extended-service-sets for each band. These would have a different SSID for each band like “Network-Name” for the 2.4G band and “Network-Name-5G: for the 5G band. The security parameters are the same for each band; and you may want to run the 2.4GHz band as “mixed mode” and the 5G band as “N-only”. The advantage of this setup is so you can identify any weak spots that affect a particular band in your dual-band wireless network and is more applicable with the 5GHz band that uses a shorter wavelength than the 2.4GHz band.

Here, you could have the main router that serves most of the house being a dual-band dual-radio type, also known as a simultaneous dual-band unit. This can also apply to an access point expected to cover a large area. Then you could use single-band or dual-band single-radio equipment for providing any infill coverage on either of the bands.

The wireless client devices

There is no need to reconfigure any of the wireless client devices such as laptop computers once you have set up the network according to the above instructions.

You will see an improvement in network performance when you operate your wireless client devices in areas where you barely could operate them. The signal-strength bar-graph that is part of your wireless client device’s network management software will register a stronger signal as the client device comes in to vicinity of the access points.

Some devices may not support this automatic roaming behaviour properly and may require you to reselect the network when you move in to the scope of the better access point.

Conclusion

Once you have followed the steps in this article, you will be able to extend the effective coverage of your wireless home network or make your wireless network cover everywhere in your house even if it uses metal-based energy-efficiency measures or has thick brick or stone walls.
