Method and apparatus to increase the backup battery lifetime in a base station

摘要

A method and apparatus for monitoring the battery capacity of the battery backup system and for compensating the RF output power to increase the service availability of the cellular base station. The present invention provides compensation of RF output power when the battery back-up system is in use for a cellular base station. By monitoring the battery capacity and power consumption of the cellular base station, the RF output power can be compensated. This compensation in RF output power will increase the time that the cellular base station can operate within the battery backup mode. This therefore increases the cellular base station service availability and does not allow for any loss of network operator income.
