To add to this discussion, most of the frequency bands allocated to amateur radio are not super useful. The 2m band is basically only good for high-ish power (>1w) land mobile communications because the antennas are fairly large. The aeronautical band right next to it is only there because when it was started, the Very in VHF wasn't hyperbole. UHF is actually much better for them because you don't need a huge antenna sticking out into the wind stream but can get more or less the same range. Similarly, the lower bands are basically useless outside of their current amateur radio purpose because nobody is going to carry around a 20m dipole to connect to their cellphone or wifi router. The only exception would be maybe the 13cm through 1.2cm bands which I could see the telcos gunning for in a few years.
