BT is looking to develop different platforms to deliver broadband services other than across copper wires. A source within BT said the monster telco was toying with different technologies, including wireless and satellite systems. He wouldn't commit further or go into any more detail about the plans, but said that the investigations were prompted by BT's cast-iron pledge to provide everyone in Britain with phone access. The reason for BT's dabbling is that ADSL technology will only cover some 80 per cent of the British population once it is fully installed up and down the country. The remaining 20 per cent, people who live more than a stone's throw away from their local exchanges, would be left broadband-less... or not, as the case may be. ®
