|FCC Is Testing Web-Over-Airwaves Device.|
Can Unused TV Airwaves Be Used for The Web Service?

|The Federal Communications Commission is expected to release findings this summer on whether a new device can deliver high-speed Internet service over unused airwaves without disrupting television programming. |
The coalition, which includes Microsoft Corp., Google Inc., Dell Inc. and others, wants the agency to open up unlicensed and unused TV spectrum, also known as "white spaces," for broadband Internet service.
However, TV broadcasters are unconvinced the device will work and said if the new technology is approved it could also cause problems with their federally mandated transition from analog to digital signals in early 2009.
The coalition, which submitted the prototype about two weeks ago, said using the white spaces would spur technological innovation and help provide affordable broadband service to millions of Americans, especially in rural communities.
This would add nice traffic to the web. I hope for it to happen. Full "AP" story [biz.yahoo.com]

What the article doesn't explain - and this is a critical point in my view - is how exactly the end user sends the upstream data. Television is a push technology, and web is pull - the scheme may well provide decent download speeds, but surely wouldn't it need to be combined with an upload connection via dialup or similar?

Very good point.
I wonder, how they are planning to solve upload problem.

But this isn't television. It just happens to use the frequency spectrum currently-allocated to television. Presumably, it would have upstream transmission as well.
How does this differ from data services currently offered by cell phone operators? Dunno. Probably not much, other than the set of monopolies running it.
IMO, there is going to be quite a frequency grab coming out of the deallocation of much of the UHF TV spectrum once the HDTV changeover is accomplished. Of course, this has been ongoing for several years now, as bits of the UHF TV spectrum have been eaten-away for other services.
The most ironic recent reallocation was the reassignment of a portion of the former-UHF-TV spectrum for - television! Qualcomm's MediaFlow technology is being used to deliver live TV to cell phones outside of cell phone spectrum allocations.
