It's All About Power
The primary cause of dropped calls is low signal output power from the cell phone to the cell tower, which limits the phone's ability to communicate with the tower. A typical cell phone provides merely one-fifth of a watt of output power. To address this problem, the amplifier and the outside antenna work together to increase the phone's output power by more than 15 times over using just the phone alone.
