Devolo Develops for 4K

Posted by Andrew at 5:29 AM on August 20, 2014

Devolo LogoDevolo today announced their new dLAN 1200+, the fastest Powerline networking adaptor in their range with Gigabit-class data transmission. The latest adaptors double the speed of the dLAN 650 by using a combination of Devolo range+ technology, the newest generation of Powerline chips and MIMO (multiple input, multiple output) technology, offering a maximum of 1200 Mb/s. This is ideal for anyone wanting to stream 4K video but doesn’t have a network point close to their UltraHD TV.

Devolo dLAN 1200+ Powerline Adaptors

With the Powerline adaptors on all the time, Devolo has kept the power consumption low. When in use, the dLAN 1200+ uses a maximum of 4.2 W, and if the connected device, e.g. TV, is switched off, the adapter automatically goes into standby mode, using just 0.7 W. If security is a concern, users can also activate 128-bit AES encryption to avoid any unauthorised access to the network.

As can be seen from the pictures, the dLAN 1200+ is equipped with a gigabit Ethernet connection and an integrated electrical socket with mains filter.  It’s fully compatible with all previous dLAN models, though the maximum speed will be limited by the slowest adaptor.

The adapters can be purchased as a starter kit for setting up a home network or as individual adapters to extend an existing network. The starter kit is priced at GB£119.99, while the single adapter costs GB£64.99. Devolo will be officially unveiling this new range of products at the IFA Conference in Berlin from 5th-10th September.

Hmm, these might be my next upgrade – hopefully they’ll be available before Christmas.

Devolo Entering Smart Home Market

Posted by Andrew at 2:16 PM on July 29, 2014

Devolo LogoPowerline networking experts devolo have announced their intention to enter the smarthome market with a comprehensive array of products including movement and smoke detectors, radiator thermostats and switchable power outlets, taking on the likes of Nest and Belkin. Branded as “Home Control”, the products will be debuted at this year’s IFA show in Berlin in September.

Focused on providing customers with greater convenience, security and energy efficiency through innovative smart home products, devolo Home Control is the first smart home system that you can build yourself. Whether it’s a coffee machine that automatically starts ten minutes before breakfast, a switch that sets the entire house to night mode, or a motion detector that can tell people from pets, the possibilities for creating a smart home are endless.”

Devolo Powerline Data Rates“Simplicity is the promise of devolo Home Control with an easy installation process removing the need for tools or cables, and a range of components that can be combined as desired. Taking example from their successful Powerline ranges, Home Control products will be available in helpful starter kits, with the ability to expand and tailor the smart home through individual products.

I run devolo Powerline at home and while their gear is more expensive than the equivalent from Belkin or TP-Link, it’s very reliable and I’ve never had to reset any of the adaptors. In addition, the complementary “Cockpit” software and app is much easier to use and runs on both my PC and my tablet. Amongst other features, the app shows the data transfer rates between the paired adaptors and makes adding in new adaptors very simple. Going back to the new Home Control, the press release mentions that the Home Control products will have a “My Devolo” and if they can keep it simple with a cool app, I think devolo will have a winner on their hands.

Interestingly, what isn’t mentioned is whether the Home Control devices will use Powerline, ZigBee (or Wi-Fi) for the controlling signals. I have problems with ZigBee and the solid walls of my house, so a Powerline-based system could be a huge advantage. I’ll be very interested to see what comes out of devolo at IFA.

TP-Link AV600 Powerline Review

Posted by Andrew at 1:02 AM on May 14, 2014

TP-LInk LogoTP-Link have been releasing steadily HomePlug Powerline products based on the AV600 standard which offers increased capacity for multiple HD streams. TP-Link have kindly sent through some of their new AV600 Powerline gear for a bit of hands-on testing. Regular readers will recall that I’d previously looked at the WiFi Powerline Extender back in December so it will be interesting to compare the faster gear. Let’s take a look.

TP-Link AV600 Box

First, for those who aren’t familiar with HomePlug Powerline, it’s a technology that uses the mains electricity circuits to transmit network signals and as most homes have power sockets in every room, it’s ideal for spreading the network round the house. This AV600 Gigabit Powerline Adaptor Starter Kit (TL-PA6010KIT) has two adaptors, one of which usually connects up to the broadband router or data switch and the other goes into the otherwise network-free room. The box also has two ethernet cables, software CD and a Getting Started guide.

Powerline AV600 Units

As you’ll see from the plugs, these are UK spec units but variants for other countries will be available. The cases are plastic but the seem well-built enough and should resist the normal bumps and knocks that can be encountered round the home. A couple of LEDs indicate the status of the network and transfer activity.

As the adaptors come pre-paired, no configuration is required and getting started is simply a case of plugging them in and attaching network cables. If the adaptors are to be introduced into an existing HomePlug network, there is a small pairing button on the bottom of each unit. Alternatively, a bundled software application can be used to manage the network and add additional adaptors.

These newer 300 and 600 Mbps adaptors use techniques borrowed from wi-fi standards to increase the throughput and to cope with noise and errors but the real-world data transfer rate will never be anywhere close to the rated speed. The overhead of encryption takes its toll on the transfer rate too, but as with wireless it’s very much a necessity to keep data away from prying eyes.

The adaptors in this starter kit come with a single gigabit ethernet port which can either connect to one device or connect into a switch or hub to share the connection. Alternatively, TP-Link have a newer 3 port AV600 version (TL-PA6030) which will keep the back of the entertainment unit a little bit tidier where there’s a smart TV, a game console and a media streamer.

Performance-wise, I did some testing using Totusoft‘s Lan Speed Test. Bear in mind that no two homes will be configured the same, so while the Mbit/s figures are of interest, it’s the relative performance that matters. With that in mind, I tested the data transfer speeds between a Buffalo NAS and a Toshiba laptop using 10 GB files.

  • Wired connection via TP-Link AV600 Powerline – 91 Mb/s
  • Wired connection via TP-Link AV500 Powerline – 72 Mb/s
  • Wired connection via ethernet – 298 Mb/s

These figures tell us two things. First, there’s a measurable performance boost between the older AV500 and the newer AV600 of around 25%. Second, there’s capacity for multiple HD data streams. A 1080p mp4 video stream needs somewhere around 22 Mb/s so at a true 91 Mb/s transfer rate, there’s plenty of capacity for several HD streams. For comparison, a Blu-ray video can output up to 48 Mb/s.

(Again for those people who get all concerned as to why I didn’t get speed “X” Mb/s, it’s the wiring in the building, combined with the features or restrictions of my laptop, data switch and NAS.)

The network management software on the enclosed CD didn’t like my Windows 8.1 and refused to install but an updated version was available from TP-Link’s website. The software lets you monitor the actual speed of the network, add additional adaptors, carry out firmware upgrades and set basic QoS. Some of it was beyond me too!

TP-Link QoS

The software is nowhere near as good as Devolo’s Cockpit but it does the job most of the time. On a few occasions I found that the app wouldn’t start properly, putting an icon into the System Tray but failing to display a window: usually a reboot resolved the problem. Many people will never need the software as they’ll only plug the Powerline adaptors in and leave them alone. However, for those who want to tinker or setup a larger network, it’s there…if you can get it to work.

Out of interest, I tried moving the receiving end around my house and there were variations in the data transfer rate – broadly, the further apart the adaptors were, the slower the rate. However the drop-off was far less than would be expected on wi-fi with very acceptable data rates throughout the building. If you are tempted to upgrade your HomePlug Powerline network, don’t forget that all the adaptors need to be of the same class (AV600) to boost the network speed.

In summary, the TP-Link AV600 Gigabit Powerline Adaptor Starter Kit improves on the previous product generations and provides fast networking via power outlets. The supporting software needs improvement but with on-line prices a little under £60, the kit is still good value.

Thanks to TP-Link for supplying the review units.

TP-Link ACes Wi-Fi at The Gadget Show

Posted by Andrew at 6:22 AM on April 18, 2014

Like many families now, it’s not unusual for everyone to be using the wi-fi network at home at the same time. Game consoles, tablets, media players and smart TVs all take their share of the data stream, and with the potential for multiple HD streams, the wireless takes a real hammering. In response to this demand, 11ac wireless uses dual frequencies and multiple antennae to get gigabit class data speeds, while still being backwards compatible with the older standards.

TP-Link Stand at GSL14

Under the Archer brand, TP-Link have a range of 11ac routers and modems, starting with twin antennae 750 Mb/s Archer C2 up to the three antennae 1750 Mb/s Archer C7. TP-Link has kindly sent one of the latter to GNC for review, so I’ll be taking a look at that later.

At The Gadget Show, I caught up with Simon from TP-Link who told me a little about their design philosophy and what they’re aiming for with the new 11ac routers.

Gigabit Powerline from Trendnet at CES

Posted by Andrew at 8:37 AM on January 5, 2014

TRENDnet LogoNetworking over electrical power lines has come a long way since the first HomePlug specification back in 2008 which was was rated at 14 Mb/s. Today network specialists Trendnet have announced a gigabit class, Powerline 1000, with the launch of the TPL-420E2K adaptors.

Trendnet Powerline 1000Based on the HomePlug AV2 standard and using MIMO techniques originally used in wireless data transmission, Powerline 1000 doubles the speed of the previous implementation.

Zak Wood, director of global marketing of Trendnet said, “Trendnet’s TPL-420E2K is designed to easily handle multi-HD streams in a busy connected home.

For the first time, Powerline products use all three electrical wires: the live, neutral, and ground (earth) wires. MIMO technology sends information over the fastest two out of the three available electrical wires. If a user lives in an old home which is not cabled with ground wires, the maximum throughput is reduced from 1,000 to 600 Mb/s.

The TPL-420E2K connects over electrical lines for distances of up to 300 m (a little less than 1000 ft), which is roughly the size of 5,000 square foot home. Powerline 1000 is compatible with existing Powerline 500, 200 and HomePlug AV rated products but when connected to a lower speed adapter, speeds are reduced to the lower rated adapter.

As you’d expected, the communication between the adapters is encrypted and to reduce energy consumption, the TPL-420E2K units go into standby mode when not in use.

The MSRP is US$169 but the Powerline 1000 units are not expected until June 2014. I’m looking forward to testing these already, especially if Trendnet produces an adaptor which incorporates a fast wireless access point.

TP-Link WiFi Powerline Extender Review

Posted by Andrew at 5:35 AM on December 9, 2013

From smart TVs to DVRs and games consoles, many items of consumer electronics now expect a network connection to download media or to upload hi-scores. Most homes don’t have ethernet cabling as standard and surprisingly few of these gadgets actually have wireless connectivity. Even then, it’s rare to have good signal throughout the house.

TP-Link Wireless Extender Box

This is where the TP-Link 300 Mbps AV500 WiFi Powerline Extender can come in, solving two problems at a stroke. First, for those who aren’t familiar with Powerline, it’s a technology that uses the mains electricity circuits to transmit network signals and as most homes have power sockets in every room, it’s ideal for spreading the network round the house. This kit (TL-WPA4220KIT) from TP-Link has two adaptors, one of which connects up to the broadband router and the other goes into the otherwise network-free room.

TP-Link Units in Box

But that’s not all….the room unit provides both wired and wireless services. A pair of ethernet ports on the bottom of the adaptor can hook up two cabled devices, say TV and DVR, and the wireless extender can strengthen the 11n network in the room to keep a games console happy. The kit can be extended with additional Powerline units to supply multiple rooms with networking.

TP-Link Side On

That’s the theory…how does it work in practice? Frankly, everything went very smoothly. Out of the box, the two units found each other and paired up across the house. The wireless unit has a clever clone feature where you press the WPS button on your usual wireless box and then the “clone” button on the front of the wireless adaptor. After a few seconds, the TP-Link adaptor then presents the same SSID and password as the existing box, but chooses a different channel to transmit on. To all intents and purposes, it appears that there’s a single wireless network in the area. Clever and very easy. (The configuration can be done manually as well.)

Performance-wise, I did some testing using Totusoft‘s Lan Speed Test. Bear in mind that no two homes will be setup the same, so while the Mbit/s figures are of interest, it’s the relative performance that matters. Remember, no-one gets real-world data transfer rates anywhere close to the headline rate because of the networking overheads. With that in mind, I tested the download speed from a Buffalo NAS to a Toshiba laptop using a 500 MB file. The figures are approx averages of a couple of tests.

  • Wired connection via standard ethernet – 146 Mbit/s
  • Wired connection via TP-Link Powerline – 72 Mbit/s
  • Wireless connection via TP-Link Powerline – 64 Mbit/s

I’m fairly impressed with those figures. Effectively, the throughput over the mains was about half what I’d get from an ethernet cable but 72 Mb/s throughput is pretty good, with the wireless not far behind.

For further comparison, I had a 200 Mb/s Belkin Homeplug system, which is a similar but slightly older technology.

  • Wired connection via Belkin Homeplug – 32 Mbit/s

Again, interesting. The Belkin is rated at 200 Mb/s with the TP-Link at 500 Mb/s. It’s perhaps unsurprising then that 32 Mb/s isn’t far off 2/5ths of 72 Mb/s.

And finally, I tried doing what you are warned against doing, namely plugging the TP-Link Powerline adaptor into an extension lead. I think the figures speak for themselves. Rubbish!

  • Wired or wireless connection via TP-Link Powerline in extension lead – 15 Mbit/s

Overall, the TP-Link Powerline units work well and they’re a good way to provide network connectivity to blackspots, both wired and wirelessly. The wi-fi clone feature makes it especially easy to setup. If you are getting some new gadgetry for Christmas that’s going to need a network connection, give this  Starter Kit a look. It’s available from all good retailers, including Amazon.co.uk for around £70. There is an older 200 Mb/s version that looks similar so make sure that you are buying the right one.

Note, all the figures above are megabits per second. No megabytes here, except for the download file size. Thanks to TP-Link for providing the Starter Kit for review.

Phenomenal D-Link Wireless Gaming Router at CES

Posted by Andrew at 1:01 AM on January 7, 2013

D-Link LogoAt CES today, D-Link will announce a phenomenal wireless gaming router that will support data transfer speeds in excess of 1 Gb/s by combining 11ac and 11n technologies in a single router.

DGL-5500 D-Link Gaming RouterThe D-Link Gaming Router (DGL-5500) uses Qualcomm’s StreamBoost technology offering Gigabit wireless speeds for fast gaming and HD video streaming to multiple devices. The phenomenal wireless speeds of up to 1.3 Gb/s are achieved by aggregating both 11ac and 11n wireless technologies. Using both, 11ac can deliver up to 867 Mb/s and 11n, 450 Mb/s, which when taken together gives the 1.3 Gb/s. In addition to wireless connectivity, the router has four wired Gigabit ports. Obviously the receiving devices will need to support the same standards and there will be data overheads but it’s still amazingly fast.

And it looks pretty cool too.

The Gaming Router represents the ultimate in home network speed and control, offering the ability to fine-tune bandwidth to deliver the high-performance hungry gamers crave,” said Daniel Kelley, Associate Vice President of Marketing at D-Link Systems. “Through the unique Qualcomm StreamBoost technology, this router intelligently optimizes a home network for the games you want when you want, making lag time, buffering and failed downloads a thing of the past. With the new Gaming Router, play against real opponents live, any time day or night, for unparalleled multi-player combat performance and first-person shooting experiences online.

The DGL-5500 will be available from late spring with pricing to be announced.

Wi3 Uses Coax for Ethernet Networking

Posted by Andrew at 9:29 AM on February 21, 2012

Wi3 CartridgesThe folks at Wi3 have developed a new and innovative way of using the cable TV co-ax wiring to carry more that just pictures. Jeffrey and Andy find out more from Adam.

The Wi3 system replaces the cable wallplate with a modular unit that offers a range of connection or transport options. The first two modules offer twin ethernet ports or a single ethernet port with wifi access point. Later modules may offer a built-in “set-top box”  with HDMI out or a small PC could even be squeezed in. And all without affecting the cable TV signal by using MoCA technology.

It only takes about five minutes to install and one of the neat things I like about this product is that the connections come sideways out of the unit. Consequently, it looks more attractive and less noticeable in the home.

The first two modules are only available to dealers at present but they will be stocked in big boxes nationwide later in the year. Prices are $150 and $200 for the ethernet only and wi-fi models respectively.
