A method and system for minimizing transmitter power levels within a cellular telephone communications network is disclosed. The method and system of the present invention are implemented within a cellular communications network which includes a cellular base station and a cellular telephone. A signal strength measurement is performed between the cellular base station and the cellular telephone. A determination is made periodically as to whether or not the measured signal strength is higher than a first threshold. In response to each determination that the measured signal strength is higher than the first threshold, the transmitter power at the cellular base station is reduced by one step such that the transmitter power levels within the cellular communications network are minimized.
