I thought the point of the whole digital switchover was to stop this sort of thing - "now we can expand without knocking out existing TV channels, because the TV channels are safely locked up in their own spectrum that isn't being underused and is just for TV". Another OfCom-plete failure.
And, to be honest, if my Freeview signal was affected, I'd be more likely to just switch it off and/or buy something more regulated from someone else. You don't get Sky or cable knocking out your transmission because the frequencies overlap with something else. Freeview will be the ones to suffer here, as well as customers.
I just love it. "Upgrade to digital", you say to all the old folks who don't know what SCART is - "You'll get a better picture more channels, and no interference - and we're turning off the old system anyway, so you have no choice". So they upgrade their aerials, fit signal boosters, change their TV or buy loads of adaptors, get comfortable and then next year it's "Oh, by the way, you have to do that all over again now because you'll get interference now from mobile phone masts and rather than just a little snow, you'll get an unwatchable corrupt MPEG stream ."
If we were talking 7000 people - okay. If we're talk 70,000 people, you have a problem. But they're honestly talking about 700,000 people - that's a good portion of the TV viewing audience across Britain. I think, if I was elderly, it would be that point at which I told them to stick it up their bum, sold my TV and stopped paying the licensing fee.
