Abstract:
1. A Power Line Communication (PLC) transmitter that connects to phase, neutral, and protective earth wires of a powerline network, the PLC transmitter comprising: a first feeding port that connects to the phase and neutral wires and that is configured to output a first communication signal for transmission from the transmitter, the first communication signal being a differential mode signal; a second feeding port that connects to the phase and protective earth wires or to the neutral and protective earth wires and that is configured to output a second communication signal for transmission from the transmitter, the second communication signal being a differential mode signal; processing circuitry configured to control output of at least one of the first communication signal and the second communication signal, for data transmission, for output via at least one of the first feeding port and the second feeding port, respectively, based on characteristics of channels fed by at least the first and second feeding ports; and transmitting circuitry that transmits data via a selected feeding port, the transmitted data being at least one of the first communication signal and the second communication signal.
