description Power Line Communication (PLC) Overview
Power line communication (PLC) is a method of sending digital data through conductors that already carry electrical power. Depending on the system, it can support networking inside buildings, communication between smart meters and utilities, or control and monitoring functions in electrical grids. PLC avoids the need for a separate data cable, but performance depends on wiring quality, electrical noise, circuit layout, and the communication standard in use. It is a wired transmission method, not a Bluetooth connection.
help Power Line Communication (PLC) FAQ
What does Power Line Communication use to carry data?
Power Line Communication sends digital data through conductors that already carry electrical power. It can therefore use existing wiring instead of requiring a separate data cable.
Can PLC be used for networking inside buildings?
Yes. PLC can support networking inside buildings by sending data over electrical wiring. The result depends on the wiring layout, electrical noise, and the specific PLC system.
How is PLC used with smart meters?
Some PLC systems carry communication between smart meters and utility operators. This allows meter data or control signals to travel over power infrastructure, depending on the deployment.
Is Power Line Communication the same as Bluetooth?
No. PLC sends data through electrical conductors, while Bluetooth uses short-range wireless radio. A device may use either technology for different links, but they are not the same transmission method.
