Abstract
The present invention discloses a power line communication system and method for transmission of RF signals through an AC power line medium. The system includes a transmitter to transmit the RF signals through the AC power line medium and a receiver to receive the RF signals from the AC power line medium. The AC power line as a transmission medium is transparent to the circuits sending and receiving the RF signals.
