G.fast
G.fast is a DSL technology that delivers higher speeds than VDSL2 over short copper lines, using a much wider range of frequencies.
What is G.fast?
G.fast (ITU-T G.9700/G.9701) is usually deployed from a street cabinet or a point closer to the customer, over the final copper connection. It can reach several hundred Mbit/s, but only over short distances, typically a few hundred metres. In BT's pilots the speed tiers were up to 160 Mbit/s and 330 Mbit/s download. Unlike FTTP, it gives asymmetric download and upload speeds.
