The G.fast standard (ITU G.9700) is currently going through its final approval process and many expect this to be completed by around Q3 2014 (here). Meanwhile BT has already confirmed the first Huawei-based trials of G.fast at its Adastral Park facility near Ipswich in Suffolk (here) and they’ve had it in the labs, touching 800Mbps+, for even longer.
The new technology is similar to BT’s existing up to 80Mbps capable Fibre-to-the-Cabinet (FTTC) service, which is currently being rolled out across the United Kingdom, although it’s designed to operate over much shorter copper lines (below 250 metres) and will utilise more radio spectrum (17 – 106MHz+) with improve noise cancellation (vectoring). Target speeds from 150Mbps and up to potentially approaching 800 – 1000Mbps are frequently talked about.
