IEEE drafts hybrid home net standard
December 14, 2010 // Rick Merritt
A handful of companies are have agreed to draft a standard that could help unify fragmented wireless and wired home networks. The IEEE 1905.1 group has backing from Atheros, Broadcom, Cisco Systems, Intel, Marvell, Toshiba and others.
Chip makers increasingly share a vision of connecting all devices to all services in the digital home. They recognize that no one network can handle that vision, so many have been hammering out hybrid home network strategies.
For example, Wi-Fi chip maker Atheros bought powerline specialist Intellon in September 2009 and announced hybrid Wi-Fi/HomePlug reference designs recently. Rival Broadcom acquired powerline chip maker Gigle in November 2010 and has similar reference designs in the works.
The IEEE effort will specifically cover Wi-Fi, Ethernet, the Multimedia over Coax Alliance (MoCA) version 1.1 spec and the two powerline technologies specified by the IEEE standard 1901.
"We identified a need for convergence between Wi-Fi and powerline in Europe, and at the same time some people in the U.S. were also targeting similar convergence between MoCA and Wi-Fi, so we all talked and there was a common will to reach a standard," said Paul Houze, chairman for 1905.1 and a standard expert for France Telecom.
In separate interviews, companies such as MoCA chip provider Entropic Communications and powerline chip maker Sigma Designs expressed support for the hybrid home network concept.
The 1905.1 group's abstraction layer will reside between the media access controller and the Internet Protocol layers. It aims to make it easier to install and manage hybrid home networks so consumers "can buy devices with several interfaces that can plug and play," said Houze.
The interface likely will require changes in home networking silicon, he added.
The standard will be extendable to work with other home networking technologies, according to a description on the group's Web site. It's not clear however if it will be useful for uniting the fragmented world of relatively narrowband home automation networks such as Zigbee and Z-Wave.All news
