Power line communication apparatus and systems used in low-voltage installations in the frequency range 1,6 MHz to 30 MHz - Part 4: Low rate wide band services (LRWBS) operating between 2 MHz and 4 MHz - Channel allocations

This European Standard applies to electrical equipment using signals in the [2-4 MHz] frequency range to transmit information on low voltage electrical systems/networks within installations in consumers’ premises for residential, commercial and light industrial environments.
The purpose of this European Standard is to describe a mechanism to limit mutual interferences between equipments operating in the [2-4 MHz] frequency band and to specify the way systems share the same band.
It does not specify the signal modulation methods nor the coding methods or functional features (except those preventing mutual interference in the same band).
Applications complying with this coexistence standard may offer low rate (lower than 1 Mb/s) services in home and building automation, street lighting control.
This European Standard covers typical applications such as energy efficiency, real-time displays of metering information, general command and control, home automation.
This European Standard does not cover high rate communication (higher than 1 Mb/s) applications such as Video or Internet networking.
This European Standard does not cover Output Voltage Levels.

33 This document [prEN 50412-4:2012] has been prepared by CLC/SC 205A "Mains communicating
34 systems", of CLC/TC 205, "Home and Building Electronic Systems (HBES)".
35 During the CLC/SC 205A meeting, held on 2010-04-27 in London, it has been decided to set up an ad
36 hoc group to clarify and improve the draft proposal coming from the French Committee on Low Rate
37 Wide Band Services (LRWBS) and to prepare a Document for Comments (DC) by the end of
38 September 2010.
39 After the examination of the concerned document during the CLC/SC 205A meeting held on
40 2011-03-29, the project was accepted with the following main amendment: to add a Clause 6 on EMC
41 requirements, referring to FprEN 50561-1:2011, Power line communication apparatus used in low
42 voltage installations – Radio disturbance characteristics – Limits and methods of measurement –
43 Part 1: Apparatus for in-home use.
44 This document is currently submitted to the Enquiry.
45 This document has been prepared under a mandate given to CENELEC by the European Commission
46 and the European Free Trade Association, and supports essential requirements of EU Directive(s).

49 Introduction
50 Low rate powerline communications (PLC) in the [2 to 4 MHz] frequency band can be used for Home
51 automation applications. The coexistence between low rate and high rate powerline communication
52 systems in this band is covered by the general coexistence mechanism called "Inter System Protocol
53 (ISP)" described in the IEEE 1901 [4] and ITU-T G.9972 [9] standards. More details are given in
54 Annex A.
55 However, when using the same [2 – 4 MHz] frequency band, different in-house PLC technologies
56 might potentially create disturbances and interferences, as power lines are a shared medium.
57 Therefore, to prevent each service from any possible interferences, it is essential to specify a
58 co-existence mechanism dedicated to the [2 – 4 MHz] frequency band.
59 It is the purpose of this European Standard to define an access mechanism (or access protocol) in the
60 [2 – 4] MHz frequency band, based on CSMA/CA, for low rate powerline communication services.
