If I have understood him correctly, he seems also to be suggesting that there is an infinite amount of transmission bandwidth available. Not so in a strict sense, but if you go to a high enough carrier frequency and cover a sufficiently limited geographical area you may be able to get enough for your purposes without disrupting other services. Or have I totally misunderstood the whole thing?
