The real problem
Wardriving for the bad guys.
Isn't it time to get rid of OFCOM? Pirate radio broadcasters may carry knives, but at least they don't steal half the TV spectrum to flog off the back of a lorry - then tell everyone they will need to buy new Freeview boxes to watch HD because of it.
They have never been on the side of the public; they are institutionally inept and they impede development of new services.
I'll bet the WiFi frequencies are better and more effectively used than any other OFCOM controlled band. Stop trying to own the air we breath and GET OUT OF THE WAY.
