Communication using power lines has a long history; indeed, the idea has been around since the beginning of the twentieth century. In the 1980s, very low-speed PLC systems were used for controlling electronic equipment such as light dimmers. However, since the characteristics for power lines to serve as a communications means have not been defined and because the characteristics of power lines will change when power equipment and household electrical appliances are connected to them, PLC systems are now more and more widely used. Indeed, the high-speed PLC is now economically viable due to advances in analog circuit technology, digital signal-processing technology. PLC systems operating now at up to 200 Mbps for access application and Gbps per in-home.
