About PLC (Carrier)

Power-line communication (PLC) is a communication protocol that uses electrical wiring to simultaneously carry both data, and Alternating Current (AC) electric power transmission or electric power distribution.
Power-line carrier communication can be used by utilities for advanced energy management techniques (such as OpenADR and OpenHAN),[15] fraud detection and network management,[16] automatic meter reading (AMR), advanced metering infrastructure, demand side management.[17] load control, and demand response.
In a two-way system, commands can be broadcast out from the master station to end devices (meters) – allowing for reconfiguration of the network, or to obtain readings, or to convey messages, etc. This type of broadcast allows the communication system to simultaneously reach many thousands of devices—all of which are known to have power, and have been previously identified as candidates for load shed. PLC also may be a component of a Smart Grid.
