The commercial, auctioned spectrum generates a lot of revenue. You note that everyone makes sure that devices sold for use in that spectrum can be controlled.
In the private spectrum, governments don’t even pay a license fee, business fees are so low as to probably cost more in FCC overhead to process than they collect for the Treasury.
In other words, there are no $$$$ provided by Private Wireless.
So, the only $$$$ involved where private wireless is concerned is that generated by those highly profitable, Chinese built FRS/GMRS radios that they don’t even stock parts for.
When the Motorola, Radio Shack cabal proposed all these retail private radio products such as MURS, they knew what they were doing. They also knew that the more congested the radio freqs become, the more folks would turn to the activation commission based commercial carriers which pay a lot more for the phones they bundle than do the FRS radio users.
Once the dust settles on the Nextel rebanding deal, and everyone starts looking for something to do, watch for thr 450 MHz private radio band to get in the crosshairs.
