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


Analog cell phones are going away.


True.


Cell phones already use frequencies in the 3 GHz region.


False.


1.9 GHz is in the -region- of 3 GHz.

..8 GHz is not in the -region- of 3 GHz.
