Abstract:
A method of determining transmitted signal power in a mobile communication device that transmits a signal to a base station and receives a signal from a base station, the method comprising:providing the transmitted signal to a receiving channel of the mobile communication device,wherein the receiving channel includes a signal strength indication (SSI) processor that detects voltage of a provided signal for correlation of the detected voltage to stored signal power values of the provided signal, such that the SSI processor detects the voltage of the transmitted signal; anddetermining signal power of the transmitted signal from a calibration table of the SSI processor during a normal mode of operation of the mobile communication device by correlating the detected voltage of the transmitted signal to stored signal power values for the transmitted signal;calibrating the detected signal voltage with the strength of a plurality of received signals having predetermined signal power;wherein the step of calibrating comprises the steps of:providing a received signal of predetermined signal power to the SSI processor, the received signal having a first signal power level;detecting a signal voltage for the first signal power level; andrepeating the steps of providing and detecting for a plurality of received signals having predetermined relative signal power.
