Communication systems for meters - Part 4: Wireless M-Bus communication

This document specifies the requirements of parameters for the physical and the link layer for systems using radio to remotely read meters. The primary focus is to use the Short Range Device (SRD) unlicensed bands. The standard encompasses systems for walk-by, drive-by and fixed installations. As a broad definition, this document can be applied to various application layers.

Kommunikationssysteme für Zähler - Teil 4: Drahtlose M-Bus-Kommunikation

Dieses Dokument legt Anforderungen an die Parameter für die Bitübertragungs- und Verbindungsschicht für Systeme, die Funk für das Fernablesen von Zählern verwenden, fest. Das Hauptaugenmerk liegt auf nichtlizenzierten Bändern von Funkanlagen mit kurzer Reichweite (en: Short Range Device, SRD). Die Norm umfasst Systeme für Walk-by-, Drive-by- und ortsfeste Anlagen. Als allgemeine Definition kann dieses Dokument für verschiedene Anwendungsschichten verwendet werden.

Systèmes de communication pour compteurs - Partie 4 : Communication sans fil M-Bus

Le présent document spécifie les exigences applicables aux paramètres de la couche physique et de la couche liaison associées aux systèmes de télérelevé de compteurs par radio. Il est centré essentiellement sur l’utilisation des bandes libres pour dispositifs à courte portée (SRD). La norme traite à la fois des systèmes de relevé mobile à pied ou par véhicule et des installations fixes. Le présent document peut s’appliquer, par extension, à diverses couches application.
