I was reading online where it said, until we learned the trick to transmitting a long way on low power cell phones were not possible.
I remember 1969 electronic class project build a 100 mw transmitter, this thing would only transmit about 200 feet.
5 watt CB radio transmitted about 12 to 15 miles on a good day.
2 meter transmitter was the best but I don't recall distance or power.
Relative that works for NSA was telling me, bug transmitters store up voice in a zip file when the file is full it transmits on a carrier pulse 1/100 of a second it sounds like static to anyone listening.
What is the transmitter power of a cell phone?
WHAT is the trick to transmitting a long way on low power that was not known 50 years ago?
