Who's surprised that the DTV transition is already floundering? Anyone? Well, definitely not me. To start, we all know that with the transition, all of that spectrum will be freed up, so the FCC has been testing prototypes of those "white space devices" designed to sense spectrum use to avoid introducing co- and adjacent-channel TV band interference. The big news? The most recent prototype submitted to the FCC from Microsoft unexpectedly shut down. So, I'm torn on this issue. Sure, it's reasonable to make use of spectrum that's going to be freed up. On the other hand, I very much agree with MSTV and the NAB that if there is not 100% assurance that these new unlicensed devices won't interfere with the existing signals, they should be greatly restricted. I think that the importance of an unhindered emergency report or breaking news story is quite a bit more than the convenience of a wireless "hot spot," though I can't say that everyone agrees -- obviously not the consumer electronics producers.
Unlicensed white space devices?
