The FCC will allow the "white space" between television channels to be used for certain devices: It's going to take some time to test and develop the precise rules. Will the 3/4rds (rural) to 1/3rd (urban) of fallow spectrum be auctioned? Given away? Allowed for mobile devices, too? Be another swath of unlicensed spectrum? A Senate bill would have forced the FCC to develop rules within 270 days and deem it unlicensed spectrum.
This spectrum could become a metro-scale wireless band. It could be used only for short-range settop box communication. Or it could become another band for mobile communications.
