homeplugThe TWG (Technical Working Group) of the Powerline Alliance has announced that they are making steady progress in the development of Homeplug AV2 specification. The group said they hope to finish the specification in the first quarter of 2011 and that they expect Homeplug AV2 specification to deliver a 5x increase in performance over existing Homeplug AV solutions. The AV2 specification will be fully interoperable with current Homeplug AV and future Homeplug Green PHY and IEEE 1901 products.

The (Alliance) is expecting a mark improvement in this upcoming specification over devices developed using the current Homeplug AV specification.  The work being done will allow devices developed on AV2 specification to exceed today’s Homeplug performance and be able to cope with next generation bandwidth hungry applications.

With an already establish HD and a growing 3D and 4K HD entertainment market, video over existing electrical wiring, internet gaming and security camera, the Homeplug AV2 specification is expected to guarantee reliable delivery of these media.

New Solutions In Homeplug AV2
One of the technology included in the new specification is Multiple-Input and Multiple-Output (MIMO), a solution which offers a significant increase in link throughput and range without requiring additional spectrum or transmitter power.

The Multiple-Input and Multiple-Output upgrade is expected to increase capacity and enable more reliable and expand home coverage. This solution is similar to the 802.11n and 802.16e wireless protocol which also use MIMO as a means of extending performance.

Another improvement is increase MAC (Medium Access Control) efficiencies that expand bandwidth throughput and lower overhead. “This increases bandwith,” said the Alliance “will further improve performance”, by extending coverage via repeating and routing technology in networks of three or more nodes.
