International Standards and Conformity Assessment for all electrical, electronic and related technologies



Reference prEN 50412-4:2012
Title 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
Project Number 23696
Abstract/Scope 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.

Normative reference (6)  

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn

(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
