It's worth noting, all the research here has been done on the UK's thick gauge copper, not the thin gauge copper used in other places like Australia. It's mostly been simulations or lab work brand new wire, not the half-rusted stuff in the ground currently. Speed also drops dramatically after 100m. The technology seems promising but it needs FttN backing it to achieve its true potential. G.fast is a way to deliver gigabit to multi tenancy dwellings like apartment buildings, it's not a DSL replacement.
