BT would have to dig up the streets where cables are underground (any modern estate). Even re-stringing the poles would be a major job.

Ignition's link gives details about what *might* be under trial by NTL. It uses out-of-band frequencies within the existing coax cable (just as ADSL does on a voice line). So, it doesn't require any digging or replacement of cable. Just a new modem and a few bells and whistles within the network. They claim it can all be installed without disrupting any existing equipment.

Note that, as it's outside the existing spectrum, this is not dependant on NTL switching off the analogue TV. It uses frequencies that are currently used for precisely nothing.

This has got to be good news. I just wonder what will be fast enough? I can't see much use for anything above 20Mb myself, but then again I did once think the internet was like teletext with pictures.
