This is the biggest issue.  There's only so much RF spectrum that can be used. 
Most of the wide spectrum is in the EHF/microwave and up part of our 
allocations.  So, in order to go "fast", we're going to have to move up in 
spectrum.  As Bob said about VHF->UHF, that implies path loss issues, which mean 
that there will have to be a lot more "digis", or very, very focused coverage 
areas.  This is not as trivial as it feels.
