ITU approves ‘G.hn’ standard for networking CE devices at home

ITU has approved a technical standard that will usher in new era in ‘smart home’ networking systems and applications. Called ‘G.hn’, the new standard will enable service providers to deploy new offerings, including High Definition TV (HDTV) and digital Internet Protocol TV (IPTV), more cost effectively. It will also allow consumer electronics manufacturers to seamlessly network all types of home entertainment, home automation and home security products, and greatly simplify consumers’ purchasing and installation processes.

G.hn-compliant devices will be capable of handling high-bandwidth rich multimedia content at speeds of up to 1 Gbit/s over household wiring options, including coaxial cable and standard phone and power lines. It will deliver many times the throughput of existing wireless and wired technologies.

Approval of the new standard will allow manufacturers of networked home devices – set-top boxes, residential gateways, computers, audio systems, DVD players, household appliances and any other device that might be connected to a network – to confidently move forward with their R&D programmes and rapidly bring products to market. Experts predict that the first chipsets employing G.hn will be available in early 2010.

The physical layer and architecture portion of the standard were approved by ITU-T Study Group 15 on October 9. The data link layer of the new standard is expected to garner final approval at the group’s next meeting in May 2010.

Also agreed at the recent ITU-T Study Group 15 meeting was a new standard that focuses on coexistence between G.hn-based products and those using other technologies. Known as G.9972, the standard describes the process by which G.hn devices will work with power line devices that use technologies such as IEEE P1901. In addition, experts say that they will develop extensions to G.hn to support SmartGrid applications.
