Powerline

Introduction

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.



Our Role & Activities

ETSI technical committee PLT (Power Line Telecommunications) standardizes PLC (Powerline Communications) systems.

Harmonized standards have been developed to allow presumption of conformity with the relevant EU/EC Directives: Commission Recommendation of 6 April 2005 on broadband electronic communications through powerlines 2005/292/EC.
 
ETSI PLT studies the technical requirements to avoid interference with users of the radio spectrum. As well as working with ETSI technical committee ERM, ETSI PLT has liaisons with the PLC Forum and CENELEC SC205A to establish a fruitful co-operation with these two groups attended by PLC experts.
