It means that no wireless transmitter is necessary in the transmitter beam for this functionality. The system would only need one wireless transmitter on the receiver beam. If the customer would like to monitor the status of wireless transmitter’s battery separately, a second wireless transmitter will be necessary on the transmitting beam.
