Power Line Communication (PLC) is a communication method that uses power lines as the medium. By using power lines as the communication network, it is possible to build a system quickly at low cost. For this reason, PLC is used for communications in smart meters (advanced metering infrastructure - AMI), home energy management systems (HEMS), building energy management systems (BEMS), and solar panel monitoring systems, part of a smart society. Communication data can be propagated through AC or DC power lines.
