Abstract
A system and method for amplifying cellular signals while maintaining the output power of the amplifier below a prescribed power limit. The network amplifier system may include a variable gain module having an input configured to receive an uplink signal from a handset and configured to apply an amplification factor to the uplink signal to generate an adjusted uplink signal. A detector is used for detecting a level of the uplink signal. A gain control module is configured to control the amplification factor in order to limit the output of the variable gain module to ensure that the level of the adjusted uplink signal does not exceed a predetermined limit. An antenna is coupled to the output of the variable gain module and is configured to transmit the adjusted uplink signal to a base station.
