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.
