I have read that unlike GSM and TDMA, CDMA can get a signal from multiple towers at once. I have just recently switched to Verizon and have been very pleased with there signal strength, etc. But my question is if you put your phone down on a desk and look at the signal strength indicator, it jumps from 3 bars to 5, to 2, to 4, etc. (and i have not moved the phone an inch) -- is this because it is using multiple towers to get the best signal. With my old service, Cingular GSM, it stayed about the same (even though it was only 1 bar or No Service).
