Patent ID: 7171179

Claim:
A method for adjusting a received signal strength indication (RSSI) module, the method comprises: receiving a first signal having a first known power level; measuring power of the first signal to produce a first measured power level; comparing the first known power level with the first measured power level; when the first known power level compares unfavorably with the first measured power level, adjusting offset of the RSSI module until the first known power level compares favorably with the first measured power level; receiving a second signal having a second known power level, wherein the second known power level is less than the first known power level; measuring power of the second signal to produce a second measured power level; comparing the second known power level with the second measured power level; and when the second known power level compares unfavorably with the second measured power level, adjusting gain of the RSSI module until the second known power level compares favorably with the second measured power level.
