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. -- Jim Pennino Remove .spam.sux to reply. |
