The freed-up airwaves in the proposal would mostly be unlicensed spectrum with "WiFi-like uses, " but at a much lower frequency than the 2.4GHz and 5GHz bands that WiFi needs today: as the first consistent, unlicensed spectrum at that range in the US, it could create opportunities for longer-ranged, free wireless that aren't even on the table in 2012.
