Abstract:
1. A method comprising: receiving, from a cellular base station, a cellular downlink signal; amplifying the cellular downlink signal with a first adjustable gain amplifier by a first amount of gain to provide an amplified cellular downlink signal; measuring, with a first RF power meter, a downlink radio frequency (RF) power level of the amplified cellular downlink signal before the amplified cellular downlink signal is combined with other cellular downlink signals for transmission to a mobile station; receiving, from the mobile station, a cellular uplink signal; amplifying the cellular uplink signal with a second adjustable gain amplifier by a second amount of gain to provide an amplified cellular uplink signal; measuring, with a second RF power meter, an uplink RF power level of the amplified cellular uplink signal before the amplified cellular uplink signal is combined with other uplink signals for transmission to the cellular base station; ascertaining a current load level of a power supply that provides power to the first adjustable gain amplifier and the second adjustable gain amplifier; comparing the downlink RF power level with a downlink RF power level threshold, the uplink RF power level with an uplink RF power level threshold, and the current load level of the power supply with a current load level threshold; and
