Abstract
The present application provides a power line communications system and method. The system comprises a power line network, a sending apparatus, and a receiving apparatus. The receiving apparatus comprises at least two PLC modems connected through a power line link. The sending apparatus sends a signal to a target PLC modem in the receiving apparatus through a power line network. The target PLC modem is at least one PLC modem in the receiving apparatus. The PLC modems in the receiving apparatus simultaneously receive a signal, the PLC modems except the target PLC modem respectively send the received signal to the target PLC modem through a wireless link, and the target PLC modem restores the signal sent by the sending apparatus according to the signal received through the power line network and the signal received through the wireless link. According to the power line communications system and method provided in the present application, the signal transmission quality is improved, and the data transmission rate and the system reliability are improved.
