FCC Publishes "White Spaces" Rules 63
Stellian writes "The Federal Communications Commission adopted a Second Report and Order that establishes rules to allow new, sophisticated wireless devices to operate in broadcast television spectrum on a secondary basis at locations where that spectrum is open. It's the first time we have access to clear specifications for these devices, dubbed TVBDs — 'TV band devices' by the FCC. The published guidelines allow manufactures to create protocols and build compatible devices, which could be available in 18 Months, according to Larry Page. The full PDF text of this Second R&O is published on the FCC site."

Advances are being made in ATSC receiver technology that improve performance in multipath environments
I agree, for static multipath, but dynamic multipath is going to be nearly impossible to fix for 8VSB. ATSC is, in fact, working on an add-on to support mobile device reception to make up for the inability for 8VSB to stand up to dynamic multipath and doppler.

By the time a distant signal reaches your set, it's only ~10 milliwatts. A 40,000 milliwatt TV Band device can easily overpower that. It's more commonsense (40000>>>10) than any real need for testing.
However if you insist upon tests, the ones performed by NAB and the Cable Association show any TV Band device within 1-2 football fields will overpower a broadcast television station. You'll end-up watching digital hash noise rather than the sports game or the latest episode of "Legend of the Seeker".

FOX News is not on broadcast television. FOX News is a cable channel.
