ITU Readies New 1Gbit/s Broadband Standard

G.fast, a new ITU broadband standard that promises up to 1 Gbit/s over existing copper telephone wires is one step closer following a meeting of ITU-T Study Group 15 this week. G.fast is designed to deliver superfast downloads up to a distance of 250 meters, thereby eliminating the expense of installing fibre between the distribution point and people’s homes.

The Geneva meeting saw first stage approval of ITU standard, Recommendation ITU-T G.9700, that specifies methods to minimize the risk of G.fast equipment interfering with broadcast services such as FM radio, paving the way for G.fast to be approved in early 2014.

G.fast is expected to be deployed by service providers wanting to provide fibre to the home (FTTH) like services, which will enable flexible upstream and downstream speeds to support bandwidth-intensive applications such as streaming Ultra-HDTV movies, uploading high-resolution video and photo libraries to cloud-based storage, and communicating via HD video.
Hamadoun Touré, Secretary-General, ITU, said: “Since the early days of the World Wide Web, people around the world have accessed the vast resource that has become the Internet via ITU standards. I applaud our membership for continuing to show great leadership in the development of these specifications that bring broadband into our homes at ever increasing speeds and at ever greater efficiencies.”

The G.fast work has attracted active participation by a large number of leading service providers, chip manufacturers, and system vendors.

An important feature of G.fast is that it will enable self-installation by consumers without a technician’s assistance. For service providers, self-install eliminates the expense of deploying technicians to the consumer’s home, thereby also improving the speed at which they can rollout new services. Consumers will benefit from not having to arrange to be at home for a technician’s visit.

“G.fast is an important standard for service providers globally. Service providers will be able to deliver fibre-like performance more quickly and more affordably than with any other approach,” said Tom Starr, chairman of ITU-T Study Group 15, Working Party 1, which oversees the G.fast effort.

“G.fast provides the speed of fibre with the ease of installation of ADSL2,” said Les Brown, Associate Rapporteur of the G.fast Experts Group.

The new G.fast standard is being coordinated with the Broadband Forum’s system architecture project, Fibre to the Distribution Point (FTTdp). The ITU-T and Broadband Forum have been working closely to ensure that G.fast solutions can be quickly placed into FTTdp deployments.
