PLC (PowerLine Communications) technology uses the existing public and private mains power wiring for the transmission of telecommunication signals, offering Internet access via electrical networks in the home and at work.
The areas of developing data transmission solutions via powerlines include outdoor (local loop) and in-house (home networking) solutions.
The obvious advantage of PLC is that it is everywhere in the developed world. PLC can deliver high speed, low cost Internet access with 'no new wires', as well as the capability for in-building Local Area Networks.
Deregulation has been a major factor in the development of Powerline (tele)communications:
Deregulation in telecommunications allows new market entrants to provide services along electricity networks
Deregulation in the power supply sector increases the demand for specific energy distribution related information systems.
Another opportunity for Powerline technology has been in the area of home-automation and in-house systems.
