how would u like to change the cell phone industry?

Analog cells phones should stop using FM and should start using AM
with SHF frequencies - at least 3 GHz and at most 30 GHz.

Maybe you should spend more time reading up on Radio systems, RF
propagation, Modulation techniques, and a whole range of other RF and
electronic related material, before you once again make a fool of yourself.
