Power frequency communication refers to a communication system that uses the power frequency as the medium. However, there are several synonyms that are used for the same. One of the most common synonyms is Power Line Communication (PLC), which is becoming an increasingly popular transmission method. Another synonym is Broadband Power Line Communication (BPLC), which is a high-speed communication method that uses power lines as its transport medium. Another synonym for power frequency communication is Power Line Carrier (PLC) communication, a technique that uses alternating current signals to transmit data over power lines. Finally, we have the term Power Line Telecommunication (PLT), which refers to a communication method similar to the previously mentioned methods but is mainly used in Europe. Regardless of which synonym is used, all refer to the process of transmitting data through power cables.
