The Wireless M-Bus – or Wireless Meter Bus – is an open standard developed for very power efficient smart metering and Advanced Metering Infrastructure (AMI) applications and it is quickly spreading in Europe for electricity, gas, water and heat metering.

Wireless M-Bus (wM-Bus) is a low-cost, low-power star network running on license-free industrial-scientific-medical bands. Based on Sub-1 GHz, wM-Bus can reach through concrete walls and long distances, with networks of as many as 1,000 nodes per collector.

Wireless M-Bus or Wireless Meter-Bus is the European standard (EN 13757-4) that specifies the communication between utility meters and data loggers, concentrators or smart meter gateways.

The Wireless M-Bus tutorial covers WM-Bus system features, network, protocol stack and Wireless M-Bus frame types. Introduction: M-Bus stands for Metering Bus which is a European Standard. It defines specifications for layer-1 (physical), layer-2 (data link layer) and layer-7 (application layer).

The Wireless M-Bus – or Wireless Meter Bus – is an open standard developed for very power-efficient smart metering and Advanced Metering Infrastructure (AMI) applications and it is quickly spreading in Europe for automatic electricity, gas, water and heat meter reading applications.

OMS wireless M-Bus (wM-Bus) is a European open standard (EN 13757) that integrates all meters and sensors into one system with full interoperability. Lansen supports the OMS specification for both Wireless M-Bus & wired M-Bus.

TI’s wM-Bus full system solution is a combination of easy-to-use development kits, featuring TI’s MSP430 ultra-low-power microcontroller and CC11xx/120x low-power wireless connectivity devices, a robust and field-proven wM-Bus stack and high-eficiency RF-friendly ultra-low-power DC/ DC devices.

Dec 2, 2024 · The Wireless M-Bus (WM-Bus) point-to-point radio protocol, using either 169Mhz or 868Mhz, is traditionally used in smart metering and smart building, particularly for its conditional bidirectional qualities and its relatively moderate consumption.

This document describes the wM-Bus physical (Phy) and link layers of the Wireless M-Bus firmware stack application, developed by STMicroelectronics in compliance with applicable European standards. Figure 3: Firmware architecture
