G.fast is a new ITU broadband standard, that promises up to 1 Gbit/sec over existing copper telephone wires, and is one step closer following a recent meeting of ITU-T Study Group 15. G.fast is designed to deliver superfast downloads up to a distance of 250m, thereby eliminating the expense of installing fibre between the distribution point and homes.
The Geneva meeting saw first stage approval of ITU standard, Recommendation ITU-T G.9700, that specifies methods to minimise 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 services with service levels comparable to fibre to the home (FTTH), 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: “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 provides the speed of fibre with the ease of installation of ADSL2,” said Les Brown, Associate Rapporteur of the G.fast Experts Group.
