Networking 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.

Based 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.
