PCMag article: Why We Need White-Space Broadband
PC Magazine has published an article about using unlicensed white-space frequencies for high-speed Internet transmissions in rural areas.
In the USA, the government is requiring all TV broadcasters to convert their analog television signals to digital signals. This frees-up all the analog TV channels on VHF (channels 2-13; 54-216 MHz) and UHF (channels 14-83; 470-1002 MHz). These frequency spectrums (white-space) could be used for wireless high-speed Internet access, especially in rural areas where there is not a lot of white-space use to begin with. And because these are lower frequencies, especially the VHF range, the signals can travel much further, which also makes them suitable for rural areas.
I'm not sure how applicable the article is to Canada, since I'm not sure if the Canadian government is going to follow the USA's lead in the matter. If anyone knows for sure, please provide info.

Just to clarify this a bit: "white space" refers to unused spaces in the TV spectrum allocation. The digital signals will still be using some of the same spectrum allocation as the analog signals, but not the VHF spectrum. For example, the CBC digital service actually uses channel 25 (which to make it consumer friendly is called "4.1") and Radio Canada uses channel 22 ("9.1").
That being said, there are some good opportunities for novel services here unless the spectrum is simply auctioned to the highest bidder. There's an article on this from a Canadian perspective at the Alternative Telecommunications Policy Forum.
