Power line communication (PLC) refers to a communication that transmits and receives data through a power line, and is a service that can use voice, data, or the Internet by inserting a power line into a socket such as an office. When using power line communication, data transmission paths, which are complicated by wired television networks, telephone lines, and optical communication networks, are reduced to one power line, and since only a power line communication modem is required, installation for power line communication can be simplified. This power line communication technology has recently emerged as a communication infrastructure (infra) to complete the smart grid (smart grid) and saves the installation cost because it does not need to install a new line by performing data transmission using the existing power line as it is At the same time, it does not use a paid communication infrastructure, so there is no continuous communication cost.
