Can White Space Internet bridge the digital divide in America?

When TV broadcasting went digital last summer, fragments of analog TV spectrum were left unused. Traditionally, TV stations used to broadcast over wireless frequencies that carry information longer distances. They used spectrum between 512 megahertz and 698 megahertz, to broadcast analog TV channels 21 to 51 which is totally unused now. Now these so called "White spaces network" are being utilized to provide high speed internet to rural America where the broadband companies did not want to go before. United States rank 17th in the International rankings for percentage of homes that have broadband/high speed connection.
Next month FCC is expected to allow commercial white spaces internet, which can bridge the digital divide and hook up 54% of rural america with high speed internet.

A company called Spectrum bridge built a white space network under FCC's experimental license in Claudville Virginea. The company setup a radio transmitter at the town's edge and connected schools, business district and few homes using modem like radio receivers. The unused frequency spectrum was used to braodcast 2.4 GHz wifi signals.  To protect the rights of current TV and wireless broadcasters, company uses its own database to assign the proper white space channels to the radios called whitefi radios.
Microsoft researchers Ranveer Chandra and others have been very instrumental in bringing White space networks to practical use of broadband for rural america. This technology can be proven very effective in the  remote country area of many developing countries where bringing broadband internet is not practical if not impossible.
