Abstract:
1. A network amplifier, comprising: an antenna for receiving a downlink signal from a base station; a communication device for receiving an uplink signal from a handset; a first variable gain module connected with the communication device, wherein the first variable gain module applies a first amplification factor to the uplink signal to generate an adjusted uplink signal, the adjusted uplink signal transmitted to the base station via the antenna; a second variable gain module connected to the antenna, wherein the second gain module applies a second amplification factor to the downlink signal to generate an adjusted downlink signal, the adjusted downlink signal communicated to the handset via the communication device; a first detector that receives the downlink signal from the antenna and determines a level of the downlink signal; a processor for executing computer-readable instructions; and one or more computer-readable media having stored thereon the computer-executable instructions that, when executed by the processor, cause the processor to determine a value of the first amplification factor, the value being a function of the level of the downlink signal, and being selected so that the adjusted uplink signal is transmitted with sufficient power to reach the base station.
