Additional spectrum becoming available for unlicensed wireless devices is coming closer to reality following a recent decision by the FCC. These devices would operate in the frequency allocations in between those used for over-the-air TV. After a lot of lobbying against the move, particularly by broadcasters that feared their TV frequencies could be trampled on, the FCC has approved these unlicensed "white space" devices.
There are numerous contentions to this unlicensed frequency, appearing more restrictive than existing unlicensed space on its surface. Most are expecting ISPs and other similar service providers to be the first takers on such hardware, though it will be a while before FCC-approved devices actually make it to market.
