Power line communications PLC is defined as data communication over power lines. The main reason to consider the medium power line for communication purposes is the extremely high penetration of the power distribution grid in most parts of the world. From urban to remote rural areas power supply lines reach practically every household and thus are available as potential carrier of communication signals. This argument extends to buildings homes businesses and mobile entities such as automobiles ships airplanes or even spacecrafts where electrical wiring enables deployment of PLC systems for internal communication. The concept of PLC is not new and has been applied by power utilities for almost a century mainly for sending control messages over medium and high voltage lines. In the late 1990s with the deregulation of the telecommunication and energy markets in Europe power utilities became more seriously interested in providing additional services through their lines. However due to unrealistically high expectations on PLC as last-mile solution for high-speed Internet access .
