Oh, they'd like to try! We WISPs use the unlicensed bands (900Mhz, 2.4Ghz, 5.1-5.8Ghz, 24Ghz & 60Ghz) to do our thing. There's so much stuff out there in those bands now, that there's no way they can take the frequencies back. The FCC did recently change the 5Ghz rules in an attempt to restrict our ability to do longer range high speed shots, but the gear is evolving faster than the bureaucrats can keep up!

It's awesome, and the upcoming generation of stuff will let our little 2-man outfit go toe-to-toe with the big guys and deliver fiber-like speeds...
