Whatever came of that? I think it died, didn't it? I think broadcasters have a legitimate gripe here. I also think that handing back UHF channels 52 through 83 was a good thing. It shows that compromises are made and that things are allowed to change as technology improves. The problem I see with using the white spaces for supposedly low power unlicensed devices is that there's no control of where these low power devices will end up being located. For example, if you live in an apartment and use an indoor antenna to receive OTA TV (and oh by the way, you have to do this because the apartment complex kindly took away your central antenna infrastructure to serve the cable community), then it's very possible that your TV viewing will be impaired. The TV signal at your indoor antenna, inside an apartment building, is often going to be weak. The unlicensed device in the apartment next door might use the same frequency as a (weak indoors) OTA station, or it might grab an adjacent channel. Even if it's a low power device, it could end up being quite a bit stronger than the legitimate TV signal, at that location. Another very likely scenario is that the unlicensed device will determine a particular frequency band is "white space" at its own location. But in your apartment, the TV channel in that band is (was) plenty strong enough to decode. So the unlicensed device, even at sub-1 watt levels, will now swamp the TV signal in your next door apartment. The guy using that unlicensed device won't notice any problem. He has cable, so what does he care? That's the problem.
