PLC (PowerLine Communications) technology used 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.

ETSI technical committee PLT (Power Line Telecommunications) standardized PLC (Powerline Communications) systems. PLT had the primary responsibility for standardization of communication devices operating on electrical networks. PLT developed ETSI deliverables to provide communications via the existing low, medium and high voltage power lines.

Harmonised 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 studied the technical requirements to avoid interference with users of the radio spectrum. As well as working with ETSI technical committee ATTM/TM6, SmartM2M (on HGI-PAS) and ERM, ETSI PLT had liaisons with the ITU-T/SG15, Broadband Forum (BBF), PLC Forum and CENELEC SC205A to establish a fruitful co-operation with these two groups attended by PLC experts.

ETSI TC PLT published TS 103 430 on coexistence of VDSL2 and PLT is aligned on Recommendation ITU-T G.9979 Amendment 1.

PLT developed Test Specifications for Plugtest on Coexistence G.Fast and PLT (SISO&MIMO) in coordination with BBF.

PLT worked on update and re-publication (TS 103 477) of ETSI GS OSG 001. This GS was originally created under the ETSI ISG OSG. 

PLT worked on Transcoding of HD and UHD video over powerline network.

The PLT Chairman with the Support of the ETSI Secretariat considered a smooth merge proposal of TC PLT with TC ATTM after summer 2017. This provided sufficient time to negotiate the update of the ToR of TC ATTM before merging TC PLT into ATTM.

The following is a list of the 20 latest published ETSI standards on powerline.

A full list of related standards in the public domain is accessible via the ETSI standards search. Via this interface you can also subscribe for alerts on updates of ETSI standards.
