Communication systems for meters - Part 8: Adaptation layer

This document describes the functionalities and specifies the requirements of an Adaptation Layer to be applied when transporting M-Bus upper layers using a wireless communication protocol other than Wireless M-Bus. These alternative radio technologies developed outside CEN/TC 294 could be based on Internet Protocol or not and operate either in licensed or unlicensed frequency bands.

Kommunikationssysteme für Zähler - Teil 8: Anpassungsschicht

Dieses Dokument beschreibt die Funktionalitäten und legt die Anforderungen an eine für den Transport oberer M Bus-Schichten unter Verwendung eines drahtlosen Kommunikationsprotokolls außer Wireless M Bus zu verwendende Adaptationsschicht fest. Diese außerhalb von CEN/TC 294 entwickelten alternativen Funktechnologien könnten auf einem Internetprotokoll oder nicht basieren und in lizenzierten oder nicht-lizenzierten Frequenzbändern betrieben werden.

Systèmes de communication pour compteurs - Partie 8 : Couche adaptation

Le présent document décrit les fonctionnalités et spécifie les exigences d’une couche adaptation à appliquer lors du transport des couches supérieures M Bus utilisant un protocole de communication sans fil autre que le M Bus sans fil. Ces technologies radio alternatives développées en dehors du CEN/TC 294 peuvent être basées sur le protocole Internet ou sur un autre protocole, et fonctionner sur des bandes de fréquences sous licence ou libres.

Introduction
This document belongs to the EN 13757 series, which covers communication systems for meters.
EN 13757-1 contains generic descriptions and a communication protocol. EN 13757-2 contains a
physical and a Link Layer for twisted pair based Meter-Bus (M-Bus). EN 13757-3 contains detailed
description of the application protocols especially the M-Bus Protocol. EN 13757-4 describes wireless
communication (often called wireless M-Bus or wM-Bus). EN 13757-5 describes the wireless network
used for repeating, relaying and routing for the different modes of EN 13757-4. EN 13757-6 describes a
twisted pair local bus for short distance (Lo-Bus). EN 13757-7 describes transport mechanism and
security methods for data. The Technical Report CEN/TR 17
