Power line communication - Standards
Several competing standards are evolving including the HomePlug powerline alliance, Universal Powerline Association, ETSI, and the IEEE. It is unclear which standard will come out ahead. X10 is a de facto standard also used by RadioShack's Plug'n'Power system.
Power line communication - HomePlug Powerline Alliance
The HomePlug powerline alliance has defined a number of standards:
- HomePlug 1.0 — specification for connecting devices via power lines in the home
- HomePlug AV — designed for transmitting HDTV and VoIP around the home
- HomePlug BPL — a working group to develop a specification for to-the-home connection
Power line communication - IEEE
IEEE P1901 is a working group for delivering broadband over power lines. The aim is to define medium access control and physical layer specifications for all classes of BPL devices - from long distance connections to those within subscriber premises. [1]
Other related IEEE groups:
- IEEE BPL — Standardization of Broadband Over Power Line Technologies [2]
- IEEE P1675 — Standard for Broadband over Power Line Hardware [3]
- IEEE P1775 — Another project approved by NesCom (IEEE Communications Society) on 12 May 2005 focuses on PLC equipment, electromagnetic compatibility requirements, and testing and measurement methods.
Power line communication - OPERA
OPERA (Open PLC European Research Alliance) is a R&D Project with funding from the European Commission. It aims to improve the existing systems, develop PLC service, and standardise systems.
Power line communication - Universal Powerline Association UPA
The Universal Powerline Association (UPA) aligns industry leaders in the global Powerline Communications (PLC) market and covers all markets and both access and an in-home PLC technology to ensure a level playing field for the deployment of interoperable and coexisting PLC products to the benefit of consumer’s worldwide.
In May 2004, the UPA interest group was established by founding members. These founding members signed a Memorandum of Understanding in September 2004, and the UPA was officially announced in December 2004. The UPA members share a vision of openness and a federated PLC world to harmonize and share standards and regulations globally.
Members of the UPA are: Ambient Corporation, Ascom Powerline Communications, Corinex Communications, DS2, EDF (Electricite de France), Ilevo - Schneider Electric Powerline Communications AB (SEPC), Itochu, Sumitomo Electric Industries, Ltd. (SEI), and TOYOCOM.
Power line communication - ETSI PLT
The following is from the ETSI PLT homepage [4].
The project will progress the necessary standards and specifications to cover the provision of voice and data services over the mains power transmission and distribution network and/or in-building electricity wiring.
The standards will be developed in sufficient detail to allow interoperability between equipment from different manufacturers and co-existence of multiple powerline systems within the same environment. Harmonized Standards will be developed to allow presumption of conformity with the relevant EU/EC Directives.
