Indeed totally off topic. Thinkbroadband have been particularly woolly 
in their coverage of this, elsewhere it is referred to as 4G, the 
successor to 3G. The problem is that after digital switchover some 
areas will be using channel 63 for digital TV and 4G mobiles will use 
channel 64 and up. Without adequate IF filtering in the TV and no stop 
band there is a risk of in band interference. Surely the answer is not 
to allow mobile operators to use channel 64 frequencies in those (few) 
areas where channel 63 is used by TV. But that would be too simple for 
Ofcom to understand...
