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.

Trendnet Compacts Powerline Adapter

Posted by Andrew at 8:50 AM on January 7, 2012

At CES, TRENDnet has launched the world’s smallest 500 Mb/s Powerline adapter with the new TPL-406E model. Look at the picture below to see the difference in size between a standard Powerline adaptor and the new model on the left. When trying to get all the modern gadgets plugged in and networked, this will certainly help where there is limited space or close electrical sockets.

“Consumers are looking for solutions to help connect their TVs to the Internet and TRENDnet Powerline products couldn’t be easier-with no complicated CD installation required,” stated Sonny Su, technology director for TRENDnet. “The TPL-406E defines a new category of ultra-compact high performance 500 Mbps Powerline adapters.”

More and more audio-visual equipment needs to be networked. In my living room, I think there are three ethernet devices (TV, satellite decoder and Bluray player) and I use a 100 Mb/s Powerline device to take the network to them. For this kind of equipment, Powerline is much more convenient than trying to setup a wireless bridge.

Available from April at all good retailers, the TPL-406E will be $60 on its own or $100 in a twin pack, TPL-406E2K.

Netgear New Routers, Wireless and Powerline Products

Posted by Andrew at 9:08 AM on February 3, 2011

Andy and Esby get the latest on Netgear from David Henry, Senior Director of Product Marketing for Netgear consumer products. There’s a range of Netgear products on show including their flagship wireless router, an N600 dual band wireless router with gigabit ports – the WNDR3700 ($169).

David covers some recent advances in router technology and how Netgear is making it easier for consumers to use what are now much more advanced products, whether it’s wifi, firewalls or routers. Frankly even I don’t understand some of the options on the more complex devices. The WNDR3700 uses push-button WPS to the get the wireless all paired up.

Many of you have wireless dead spots in your home, often because of the fabric of the building or else simply because of the location of the inbound cable or telephone connection. You also may not be able to replace your main router if that’s provided by your cable supplier. If you are in this situation, check out their wireless range extenders.

If wireless isn’t for you, David also covers the new 500 Mb/s Powerline (Homeplug) products and how to get your connected TV or media streamer wired up with network connectivity. For HD video, you need fast data rates and these will deliver the data rates you need.

Lots of great info here on what’s new from Netgear so give it a watch.
