Abstract
A wireless transmission system includes a transmitter antenna configured to transmit AC wireless signals to the at least one antenna, the AC wireless signals including wireless power signals and wireless data signals, the transmitter antenna including a source coil and an internal repeater coil. The system further includes at least one sensor configured to detect electrical information associated with the electrical characteristics of the AC wireless signals at one of the source coil or the internal repeater coil. A demodulation circuit is configured to receive the electrical information from the at least one sensor at the internal repeater coil, detect a change in the electrical information, (iii) determine if the change in the electrical information meets or exceeds one of a rise threshold or a fall threshold, if the change exceeds one of the rise threshold or the fall threshold, generate an alert, and output a plurality of data alerts.
