Power Line Communication (PLC) is a communication method that uses power lines as the medium, so that it is possible to build a system quickly at low cost. Using this method, communication data can be propagated through AC or DC power lines. For example, building automation can be realized using existing AC power lines in the building. Alternatively, DC power lines can be used for communication between devices, reducing device harnesses.
Renesas provides a narrow-band PLC modem IC, R9A06G061, which enables high-speed communication over 1Mbps and stable long-distance communication over 1km for peer-to-peer networks.
