How I would like to change the cell phone industry [was AM electromagnetic waves: 20 KHz modulation frequency on an astronomically-low carrier frequency]

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. |
