What bands are you talking about? The spectrum map doesn&#x27;t seem to show the wholesale wasting of spectrum you seem to imply, especially in the GHz range which is most useful for cell phones et al.<p>As you mention police, I&#x27;ll also point out public service frequencies (Part 90) recently went to 12.5kHz bandwidth (half what hams use) and there is discussion of going even further.<p>The really legacy allocations like broadcast TV, AM radio, and radionavigation are in spectra that Johnny Startup probably isn&#x27;t interested in. Data rates are pretty slow at 30kHz.
