Abstract
A small number of transmissions are performed at a sufficient number of frequencies and power levels so that a correlation between frequency, measured power, and detector values is established. Once a correlation is established, the wireless transmitter employs the measured data and calculates target detector values for all supported frequencies and at all supported power levels, eliminating the need for one frequency and one power level at a time iterations with a host device. Using the calculated target detector values and closed loop transmissions, the radio self-calibrates. Once employed in the field, the wireless transmitter can utilize measured changes in signal strength to determine when to re-calibrate, and using measured values from other network components, can employ the methodology of the present invention to self-calibrate, eliminating the need for field re-calibrations.
