This BBC article says ofcom have realised that the 4G (the next mobile broadband) spectrum is too close to digital TV spectrum, so there may be interference.
I find it strange ofcom only realised this recently, long after they had planned the spectrum reorganisation (after the analogue TV is switched off, leaving empty spectrum).
The obvious solution is to get rid of digital TV and just do it over the internet (ya know like TVCatchup).
But the 4G spectrum is only being sold to networks in 2012 (america already ahve 4G networks, and well South Korea are light years ahead of us), well thats what the government is planning, so you can bet they'll start in 2013, and it will only reach consumers in late 2014.
Anyone else think that we should just pay for one network that can do everything than paying for many different networks each with their own [expensive] equipment, ie get rid of TV, radio, and cable and replace them all with 4G, leaving only one network to be upgraded, instead of 4.
