In mobile radio networks the participants are transmitting information by using radio band broadcasts. The topology of the network is organized in cell units. In the same cell the transmitters are using the same radio frequency. This frequency varies from one cell to another. The radio networks have employed radio frequency power control to minimize the transmitter power to a certain level which is able to ensure adequate speech quality and to reduce the cell-to-cell interference. The control loop for power control (PC) is based on measurements of the controlled system parameters. In current radio networks the power control decision is based on the received signal quality RXQUAL, which is mapped to C/I values to get a better resolution, and the received signal level RXLEV. Both measures, signal quality and signal level, are used to keep the operational range within a predefined power control window, the center region shown in Fig. 1.
