Power-line communication (PLC) systems have been assumed as the systems of low speed and low reliability. The low qualities of the systems, however, are not inherent of PLC but the result of inadequate design strategy of the systems. The systems with proper considerations of the characteristics of power-line as a communication medium achieve reliable high-speed data transmission in power-lines. In fact, the activities on the standardization of high-speed PLC systems have recently started in many countries, and variety of high-speed PLC systems are being to be purchased off-the-shelf. Following this trend of PLC, this manuscript first describes the features of power-line for communications and then explains technical issues on the design of PLC systems of the next generations as the infrastructure of information-communication technology age.
