PLC (Power Line Communication) is a technology that transmits data over existing electrical power lines by superimposing high-frequency communication signals onto the power wiring. It enables LAN construction without the need for new network cabling and is also used in IoT area networks. Its key advantage is that any location with electrical wiring can serve as a communication link.
