The main difference is that we currently connect via copper into people’s homes using ADSL technology. This mixes voice and data signals over the copper and then separates them via a modem inside the home. The problem with this is that the further away from the exchange a home is, the slower the speed. For example, using DSL technology beyond 4.5km, services faster than 1 Mbps cannot be reliably delivered. To reach speeds like 12 Mbps consumers need to be as close as 1.5km to the exchange.
