Short term gain, and really killing the future.
Imagine a device in you pocket, it does a lot of communicating, but it does it smartly.
A short distance communication, within the room, it will do point to point analog. No cells involved.
A medium distance communication, in the neighborhood or building, it may use a pico/nano cell.
A long distance communication, it will use a cell as needed.
It can receive broadcast (AM/FM/TV) without any special extra hardware.
It can do only digital communications, as needed, for voice, data or anything else.
It can locate other uses via the cell network, to know what mode will be the most efficient communications means.
The device is smart, and uses software defined radios. It will use the proper spectrum and modes to accomplish the communication. Analog voice, use SSB; CDMA for cell or as needed; proper psk, for digital, etc.
But... to make this work, the spectrum needs to be available. If it is all sold off, the program won't work. The cell carriers can still make money with the locator service, (maybe not as much, but they are about to not make as much due to other pressures)
If we keep auctioning off all the spectrum, there will be no opportunity to get any of this. We will still have to use the inefficient modes we have today, filling the available spectrum with overhead.
