According to recent theoretical reports from communications regulator Ofcom, speeds on copper lines used for broadband could reach 50Mbits/sec if operators’ modems were moved from exchanges to street cabinets.
Fibre-optic cable would need to be run to the street cabinets to achieve the high speeds, but this is far cheaper than running it to the home.The top broadband speed would be available to anyone living within 2km of a cabinet, which is nearly everyone. Current modems in local exchanges provide top data rates to only 18% of homes.
