What is PLC ?

PLC is an abbreviation for "Powerline Communication". You will also find the terms PLT ("Powerline Transmission") and BPL ("Broadband Powerline") having the same meaning.

The power supply network is used for transferring Internet-specific data. One connection can be used by a number users and everyone of them might be able to read communication data of all others at the same cable.

Data is transferred over ordinary mains networks. The used frequency range is usually below 30MHz. This range is also called "Shortwave Radio" (see also What is shortwave radio?).

Actually, mains networks are not suitable for high-frequency data transfer. As those lines do not have any electromagnetical shield, they act like an antenna and radiate interferences.
