1. A method of controlling a transmission signal power level of a transmitter, comprising:

  • receiving a target power level;

    determining duty cycle of a transmission signal that indicates power on and power off periods over a predetermined sensing interval;

    sensing a transmission signal power level;

    adjusting the transmission signal power level to be approximately equal to the target power level divided by the duty cycle;

    receiving a transmission indicator that is active during transmission of signals;

    at least sensing the transmission signal power level while the transmission indicator is active.
