Re: LTE-U
But the FCC has already released its authority on certain frequencies. That's why it's called unlicensed spectrum. They're anarchy zones, basically, and as far as regulation is concerned, the genie's already out of the bottles with unlicensed spectrum. If the FCC tried to reclaim them, they'd run into tons of interference.
Now, if a device using unlicensed spectrum crosses into licensed spectrum, then it's the FCC's job to look into it. But apart from that (and perhaps some token ground rules the FCC may have set), unlicensed spectrum is pretty much every device for itself. If LTE-U uses unlicensed spectrum, it will have to give and take with everything else there.
