At this point I don't think these devices are even transmitting, they are being tested for how effectively they are able to detect signals from microphones etc.
Their record appears to be less than perfect on this, but not as horrible as opponents claim. Whether the technology should have to be perfect before it is allowed to be developed commercially should be another discussion because I don't think that is the standard that is typically used.
At any rate this is quite a distance from saying that these devices will interfere and an even further distance from saying that they will bring enormous chaos.

The problem is largely that a rooftop antenna can receive a perfect DTV picture from a channel that a little stub antenna on the WSD cannot detect from some kid's bedroom. The kid's WSD will start transmitting on that channel and could easily wipe out the rooftop antenna's picture. |

Bingo, licensed fixed white space devices can have large enough antennas properly polarized but cheap unlicensed portable devices won't have adequate antennas to always detect TV signals. Where they will be used (in close proximity to people watching TV) will also be very different than the non-residential venues where wireless microphones are typically used. |

Cyberspace | Thus the issue I have with "White-Space" devices. I'm at 76 miles from the DTV transmitters with a Channel Master 3020 VHF/UHF/FM antenna, that is elevated 60' above ground level. I have 2-edge reception with a Channel Master pre-amp. I don't get nearly the DTV channels I do analog and I'm waiting for Feb 2009 to hopefully get better results.
This "White-Space" issue could be the nail in the coffin of OTA for me.
