Powerline Ethernet group posts 1Gb/s spec

HomePlug AV2 ready for adopters' adapters

Choosing a cloud hosting partner with confidence

CES 2012

Powerline Ethernet promoter the HomePlug Alliance has published its latest technology update, offering a peak data transfer speed of 1Gb/s.

That's the maximum physical data speed. Error handling and other network protocols will reduce the effective data rate to 500Mb/s. The electrical environment in which the technology is used - your home's wiring, in other words - will reduce it further.

HomePlug AV2, as the new spec is called, is interoperable with HomePlug's existing 200-500Mb/s HomePlug AV tech, and emerging 1901-based products, such as Netgear's latest powerline adapters, which also operate at up to 500Mb/s and are compatible with HomePlug AV.

AV2 takes in support for multiple input and multiple output, allowing more data to be transmitted and received simultaneously. The spec also calls for adaptors to incorporate repeater functionality to increase the powerline Lan's range.

With the AV2 spec published, it's now up to makers of HomePlug-compatible kit to incorporate the technology in new adapters. They are not likely to hit the shops until toward the end of the year. ®
