Power line communication

Power line communication (PLC) is a method of communication using the electric power transmission grid.

There are two main classes of PLC :

- PLOC ( Power Line Outdoors Telecoms ). This is the telecoms between electric substations and home networks (electro-modems). The standard is ETSI PLT (http://www.etsi.org/plt/)

- PLIC ( Power Line Indoors Telecoms ). This is using the home grid to establish telecoms. An example is Homeplug (http://www.homeplug.org). PLIC is one of the technologies used in domotics (another is wireless telecoms).
