My Comments

D-Link are another company who are emulating the success of the Apple AirPort Express multifunction device by offering a device that works as a 2.4GHz wireless range extender or a network audio player for the home network.

The DCH-M225 Wi-Fi Audio Extender can extend a 2.4GHz 802.11n Wi-Fi segment’s range using dual-stream technology and WPS “push-to-connect” enrolment. Or it can work as a Wi-Fi-connected audio player according to either AirPlay or DLNA MediaRenderer standards, thus making it feasible to play out music from your smartphone, tablet or computer to your favourite stereo equipment that is connected to this device. It would earn its keep in the “smartphone-based DLNA’ setups as well as with music piled up on a DLNA media server as described in this feature article.

Personally, if I wanted this device to be a direct competitor to what Apple offers, it would have to have an Ethernet port so it can also work either as a wireless client bridge or an access point as well as the music player and wireless-network range extender.

At least D-Link is using the audio playback functionality as a way to differentiate itself from the horde of wireless-network extenders that is being offered.

D-Link SharePort DIR-505 is a router / repeater that fits in your pocket, ships today for $70 | Engadget

My Comments

There have been a smattering of “travel routers” released on the market through the past ten years. These devices typically had a Wi-Fi access point and an Ethernet socket and were able to be set up as an access point or router. They were typically pitched at travellers who wanted to share a wired Internet access service, typically in their hotel, amongst Wi-Fi-only devices.

Now D-Link have come back with one of these routers but it also works as a “universal wireless range extender” and an access point that shares files from a USB storage device.

Personally, what I fear of devices like the D-Link DIR-505 is that they could become the “same-old same-old” where they have the same functions for their device class as everyone else but no more. The D-Link device had moved towards an AC-powered device that combines the previous travel-router/access-point model along with the same function model as devices like the Kingston Wi-Drive.

This could be a chance for manufacturers to break from the mould by doing things like making one of these devices become a wireless-broadband travel router, support multiple USB devices or use CIFS (de-facto network-file-transfer standard in desktop operating systems) and DLNA for file and media management.

At least D-Link have taken the step further with this class of device by amalgamating the travel router and the “storage access-point” device classes in to a single device.

Consumer Electronics Show 2011–Part 3

Now we come to the issue of network-infrastructure equipment that will need to support the increasing demands placed on the home network by the previously-mentioned smartphones, tablet computers and Internet-enabled TVs.

Network Infrastructure

Network Connectivity

Some newer chipsets have appeared which will increase network bandwidth for the 802.11n Wi-Fi segment and the HomePlug AV segment. The current implementations may use manufacturer-specific implementations which won’t bode well with the standards.

The first new “call” is the 450Mbps 802.11n WPA2 WPS Wi-Fi segment which is being provided by most network makes for their midrange routers and access points. Access points and routers that work with this specification use three 802.11n radio streams to maintain the high throughput. The full bandwidth may be achieved if the client device is equipped with an 802.11n wireless network adaptor that supports the three streams but your existing devices may benefit due to reduced contention for the wireless bandwidth due to the access point / router offering three streams.

Most of the routers shown at the Consumer Electronics Show this year that support the 3-stream 450Mbps level for the 802.11n wireless network functionality also offered dual-band dual-radio operation to the same specification. Here, these devices could work on both the 2.4GHz band and the 5GHz band at this level of performance.

Some manufacturers were trying out the idea of a 60GHz high-bandwidth media network which may be based on a Wi-Fi (802.11 technology) or other proprietary scheme. This could lead to three-band multimedia routers and access points that use 2.4GHz and 5GHz for regular whole-home wireless networking and 60GHz for same-room wireless networking.

The second new “call” is the 500Mbps throughput being made available on high-end HomePlug AV devices. These powerline network devices may only achieve the high bandwidth on a segment consisting of the high-bandwidth devices that are based on the same chipset. Here, I would wait for the HomePlug AV2 standard to be fully ratified before you chase the 500Mbps bandwidth on your HomePlug segment. Of course, these devices can work with HomePlug AV segments.

The third new call is for midrange high-throughput routers to have Gigabit on the WAN (Internet) port as well as the LAN ports. This is more relevant nowadays as fibre-based next-generation broadband services are rolled out in most countries.

Everyone who exhibited network-infrastructure equipment offered at least one 450Mbps dual-band dual-radio router with Gigabit Ethernet on the WAN (Internet) connection as well as the wired-LAN connection. As well, most of these routers are equipped with circuitry that supports QoS when streaming media and some of them have a USB file-server function which can also provide media files to the DLNA Home Media Network.

Trendnet also offered an access point and a wireless client bridge that worked to this new level of 802.11n performance. They also demonstrated power-saving circuitry for Wi-Fi client devices which throttles back transmission power if the device is in the presence of a strong access point signal for their network. This was ostensibly to be “green” when it comes to AC-powered devices but would yield more real benefit for devices that have to run on battery power.

They also ran with the TPL-410AP which is a HomePlug AV Wireless-N multi-function access point. Another of those HomePlug access points that can “fill in the gap” on a wireless network or extend the Wi-Fi network out to the garage, barn or old caravan.

They also issued the TEW-656BRG 3G Mobile Wireless N Router, which is an 802.11n “MiFi router” that is powered by USB and works with most 3G / 4G modem sticks available in the USA. It is of a small design that allows it to be clipped on to a laptop’s lid or a small LCD monitor.

TP-Link had their 450Mbps three-stream dual-band dual-radio router with Gigabit on bot WAN and LAN Ethernet connections. As well they fielded a single-stream 150Mbps USB stick as the TL-WNT23N.

They also tried their hand with IP surveillance with the TL-SC4171G camera . This camera can do remote pan-tilt, and 10x digital zoom. It connects to the network via Ethernet or 802.11g Wi-Fi (not that much chop nowadays) and is equipped with an IR ring for night capture, as well as a microphone and speaker.

Netgear were more active with the 450Mbps three-stream routers with Gigabit LAN. Two of the models are broadband routers with Gigabit WAN, while one is an ADSL2 modem router which I think would serve the European and Australian markets more easily. The top-end model of the series has a USB file server function which works with the DLNA Home Media Network and also with Tivo “personal-TV devices”.

They also released the XAV5004 HomePlug AV switch which is the 500Mbps version of the their earlier “home-theatre” four-port HomePlug switch. Of course, they released the XAV2001 which is a compact “homeplug” adaptor which connects to the regular standards-based HomePlug AV segment.

They also have released the MBR1000 Mobile Broadband Router which works with 3G/4G wireless broadband or  Ethernet broadband. This unit is being provided “tuNrnkey” for Verizon’s new 4G LTE service.

Netgear have also fielded the VEVG3700 VDSL2/Gigabit Ethernet dual-WAN router with Gigabit Ethernet LAN, Cat-IQ DECT VoIP phone base station. This device, which is pitched at triple-play service providers also supports DLNA server functionality. As well, they also had a DECT VoIP kit available for these providers

As well, Netgear have tried their footsteps in to IP-surveillance for home and small business with a camera and an Android-driven screen for this purpose.

D-Link’s network hardware range include the three-stream 450Mbps routers with Gigabit WAN/LAN, a multifunction access point / repeater for the 802.11n network as well as a new DLNA-enabled network-attached storage range

As far as the MoCA TV-coaxial-cable network is concerned, Channel Master is the only company to release any network hardware for this “no-new-wires” network. It is in the form of a MoCA-Ethernet 4-port switch for the home theatre.

“Mi-Fi” wireless-broadband routers

Every one of the US cellular-telecommunications carriers are catching on to the 4G bandwagon not just with the smartphones and tablets but with the wireless-broadband routers.

Sprint have a unit for their WiMAX service while Verizon are fielding a Samsung LTE “Mi-Fi” as well as the aforementioned Netgear MBR1000 router.

Computer hardware and software

Monitors

Some of the companies who manufacture monitors are looking at the idea of “Internet-connected” monitors which have a basic Web browser in them so you don’t have to fire up a computer to view the Web.

CPU/GPU combo chips

These new processor chips combine a CPU which is a computer’s “brain” as well as the graphics processor which “draws” the user interface on to the screen. AMD and Intel were premiering the “Accelerated Processor Units” and the Core “Sandy Bridge” prcessors respectively at the CES this year.

Intel were trumpeting the fact that this technology could make it harder to pirate movie content but this is more about mainstream computing and small-form-factor hardware being behind this space and power saving processor hardware.

Sony had lodged a commitment to AMD to use the Zacate “Accelerated Processor Unit” in some of their VAIO laptops.

Other hardware

AMD haven’t forgotten the “performance computing” segment when it comes to processor chips and released the quad-core and 6-core “Phenom” desktop and gaming-rig CPUs.

Seagate have also made the “GoFlex” removable / dockable hard disks a standard by building alliances with third-parties to make hardware that works to this standard. Could this be another “VHS-style” alliance for dockable hard disks?

Microsoft also used this show to premiere their Touch Mouse which uses that same touch operation method as Apple’s Magic Mouse. Do I see an attempt for them to “snap at” Apple when it comes to “cool hardware” as well as software?

The Microsoft Platform

There has been some activity with the Microsoft Windows platforms now that set-top boxes and tablet computers are becoming the “order of the day”

One direction Microsoft is taking is to port the Windows Platform, which was primarily written for Intel-Architecture processors, to the Acorn ARM-architecture processors. The reason that this port is taking place is due to these energy-efficient RISC processors being commonly used in battery-driven applications like tablet computers. They are also popular with other dedicated multimedia devices like set-top boxes and TV applications.

As well, Microsoft will be working on a lightweight Windows build for TV applications like set-top boxes. This is although they have previously written Windows-CE builds for this class of device.

Microsoft also want to make a variant of the Windows Phone 7 for tablet computers and are starting work on the Windows 8 project.

Similarly, Somsung has demonstrated the second incarnation of the Microsoft Surface platform This one comes in a slimmer table-based form rather than a unit that is as thick as the 1980s-style “cocktail-table” arcade game machine.

Conclusion

The Consumer Electronics Show 2011 has certainly put the connected home on the map. This is due to affordable smartphones and tablet computers becoming more ubiquitous and Internet-provided video services becoming an increasing part of American home life.

It will be interesting to see what will happen for the other “pillar” of the consumer-electronics trade fair cycle – the Internationaler Funkaustellung; and how more prevalent the Internet TV, smartphone and tablet computer lifestyle will be in Europe and Asia.

My comments

I had previously mentioned the D-Link DIR-685 Wireless-N Broadband Router / Electronic Picture Frame in this site during my coverage of the CES 2009 show in January 2009. This warranted my attention because of a storage router that also worked as an electronic picture frame because of its colour LCD display.

This router also was part of the DLNA Media Network because it could become a DLNA media server for material held on a user-installed hard disk or an external USB-based storage device. But this functionality has been extended through the latest firmware update for it to become a control point in the DLNA Media Network as well as showing pictures held on other DLNA Media Servers on that same network.

By the same token, the screen can be controlled by other DLNA Media control points such as TwonkyManager or a control point integrated in a smartphone like Andromote (Android), PlugPlayer (iOS – iPhone / iPad / iPod Touch) or the one that part of most of the Nokia phones.

At the moment, the utility of this function is limited to digital images because there isn’t any sound-handling functionality in this router.

This could lead to ideas like a “two-box two-screen” network solution for visual merchandising consisting of this router and a Sony or Samsung DLNA-ready TV with images shown on both the router and the TV. Similarly, this device could be seen as another “screen” for pictures to appear in another area but sharing a common pool of pictures in the network.

Therefore this is another example of a common standard breeding product software innovation rather than an imitative design culture.

My comments on this new device class

What we are starting to see is the arrival of the “multimedia router” which is a device that is primarily targeted at the home and small-office user, the people whom this blog is written for.

What is this product class

This product class is a single-band Wireless-N broadband (Ethernet WAN) router with integrated multimedia playback functionality through an integrated screen and / or speakers. They have access to the popular online multimedia services and are able to play media held on local storage.

The screen in some of the devices also acts as a local “instrument panel” for these routers and if the device has a touchscreen, it could permit the device to have a local control panel.

They have come about because the cost of integrating these functions in the one shell has become very cheap and it has allowed manufacturers to differentiate their product range in a deeper manner.

Could this product class have a place in the broadband-router market

These devices may appeal initially as a novelty device but they could add an independent media playback device in the location where the Internet router would also go. This would typically be the home office or study or the back office of a small shop. In households where the phone is customarily installed in the kitchen or hallway, it could be feasible to make maximum benefit of these locations by locating these routers there alongside an Ethernet-ended DSL modem because these units could provide a picture display or “there-and-then” information display and, in the case of the proposed design, Internet radio in one box.

Similarly, even if another router like a VPN-endpoint router is on the network edge, these units can work as an integrated multifunction wireless access point that can be moved around the house.

What the device class needs

The first two iterations of this device class need to support DLNA-compliant LAN media playback so that media held on NAS boxes and media server devices that exist on the local network can be played through these devices. They could support DLNA MediaRenderer functionality as a controlled device so a PC or other device can become the control point.

They would also have to work well as an access point or as a router with a simple configuration routine for units that are connected to existing routers. They could support working as dual-band single-radio or dual-band dual-radio access points for those networks where a dual-band 802.11n segment exists.

These kind of features could be introduced in to this device class as more manufacturers introduce devices in to the class and the competition heats up. The previously-mentioned DLNA functionality could come in to play through a firmware update during the existing router’s service life.

Conclusion

Once this device class is developed further, it could be the arrival of a router that can acceptable be on show in that credenza in the home office.

CAPTCHA in the home-network router

 D-Link First to Add CAPTCHA to Its Home Routers to Help Prevent Against Attacks

D-Link’s CAPTCHA in action | DigitalMediaPhile (Barb Bowman)

My comments on this feature

A lot of blogs, comment pages / forums, social-network sites and Webmail services use a CAPTCHA as part of verifying what kind of user is signing up or adding comments to the blog or forum. Infact, users who wish to contact me via the blog’s contact form will be using CAPTCHA as part of proving who they are. This method, which typically requires a user to transcribe letters or numbers from a purposefully-distorted machine-generated graphic, has worked for a long time as a way to keep spambots from these sites.

By the way, a CAPTCHA-based verification system is a feature that I would like to see as part of adding comments to a blog post like this one or others on my blog. It would make life a lot easier for blog authors like myself when it comes to sorting out genuine comments from irrelevant comment spam.

This technique has been added as part of a firmware upgrade to most current-issue D-Link routers in response to recent security attacks against this class of equipment. These threats, typically in the form of Trojan Horses, take advantage of home-network equipment that is ran at “out-of-the-box” settings because most home users may not know how to configure the devices properly.

What will typically happen with these routers is that if the user wishes to change configuration or set up / modify an administrator account, they have to transcribe characters from the machine-generated graphic in a similar way to authenticating themselves with a blog or Webmail service on signup.

But this kind of security will not replace common-sense network security practices like setting the SSID of your wireless network away from the default and using a strong password on the device’s administrator account. It will augment these measures and more home-network equipment should be equipped with these features. Other practices that can be implemented for best security could include devices working on “least privilege” all of the time with the option of password and CAPTCHA verification for serious configuration tasks. This is similar to how Windows Vista and Windows 7 operate; and how a properly-setup building alarm system operates. For example, the network status page on a router could be available “without login” but you have to log in to change status.

At least this is one step being made towards a secure home and small-business network.
