Powerline Communication (PLC) is a technology that enables data transmission over existing electrical power lines. It allows devices to communicate by sending digital signals through the same wires that deliver electricity, eliminating the need for additional cabling. This can be useful for various applications, including home networking and smart grid systems. PLC can be used in both residential and commercial settings, providing a convenient way to connect devices like smart meters and home automation systems. It offers a cost-effective solution for extending internet access and improving communication without the need for extensive infrastructure changes.
