In this paper, the authors constitute an overview of the research, application and regulatory activities on power line communications. Transmission issues on the power line are investigated and modeling approaches illustrated. Contemporary communication techniques and reliability issues are treated. Power lines constitute a rather hostile medium for data transmission. Varying impedance, considerable noise, and high attenuation are the main issues. The Power Line Communication (PLC) is a new technology open to improvements in some key aspects.
