The first global standard offering an in-home, high-speed network capable of delivering room-to-room HDTV has been agreed by Geneva-based International telecommunication Union.

The standard, published under the G.hn banner, promises high quality multimedia over power, coaxial, phone and other home network wiring. It will give up to 20 times the throughput of existing wireless technologies and three times that of existing wired technologies.

The specifications will be used by chip manufacturers to build transceivers that can be incorporated into set-top boxes, residential gateways, home computers, home audio systems, DVD players, TVs or any other device that might be connected to a network now or in the future.

Experts say that silicon companies will immediately start incorporating the specifications into transceivers, implying that G.hn-compliant products could be on the market as early as 2010.

Work on G.hn was started at the instigation of service providers looking to extend broadband and video services in the home. As well as its offer of greater speed, it may be bundled as complementary to Wi-Fi where G.hn offers greater coverage, extending, for example, to areas of a house where Wi-Fi does not reach.

The standard has achieved remarkable industry backing even before its publication. An industry group – the HomeGrid Forum – has been formed specifically to back G.hn. The goal of HomeGrid Forum is to market G.hn worldwide and to create a compliance and interoperability programme to ensure that products based on the standard will operate in any home around the world.
