Wireless M-Bus is an industrial wireless protocol that was developed as a standardized solution for wireless meter reading (EN 13757) and provides interoperability between different vendors. The use of an RF module ensures standard compliance and the flexibility to choose between different modes and frequency bands depending on the application and geography. Radiocrafts is a leading provider of Wireless M-Bus solutions and takes an active part in the standardization work in CEN and OMS.

Product Details

The Wireless M-Bus RF Transceiver Modules are compact surface-mounted high performance modules with embedded Wireless M-Bus protocol. The RC11xx series covers 868 MHz, as well as variants at 433, 865 and 869 MHz. The RC17xx series covers 169 MHz. The module can be configured to operate as a Slave (in the meter), Master (in the concentrator), or as a Repeater (single hop).

The module has an easy to use UART interface for serial communication and configuration and a one-pin antenna connection. When used with quarter-wave antennas a line-of-sight range of over 800 meters can be achieved (2-3 km for High Power version). Ultra low power mode extends battery lifetime.

The MPC1 (M-Bus Pulse Counter) variant contains an autonomous application for pulse counting and transmitter scheduling. It also supports over the air configuration and installation.

  • Full feature Wireless M-Bus stack embedded
  • EN 13757-3:2013, EN 13757-4:2013 and EN13757-5:2013
  • 868 MHZ (C,R,S,T modes) and 169 MHz (N mode)
  • 433, 865, 915, 923 MHz for non-EU operation
  • Master module with 256 slaves
  • Auto-message generator
  • AES-128 hardware encryption
  • Designed for Open Meater Reading (OMS) specification
  • Designed for NTA8130/DSMR/SMR
  • Special support for CIG (Italy) TS 11291-11-4
  • UART interface for communication and configuration

  • Ultra low power modes for battery lifetime > 15 years
  • High power option (27/30 dBm) in same footprint
  • Compact shielded module 12.7 x 25.4 x 3.3 mm for SMD mounting
  • Designed for EX compliance

For all our TinyMesh-protocol modules there are available Demo Kit suitcases for rapid prototyping and proof of concept. The kits contain:

  • Three Demo Boards with the module of choice, onboard USB levelshifter and USB connector
  • Antennas. Quarterwave stub w/SMA connector
  • USB cables
  • For demo kits for RC1170HP-TM and RC1180HP-TM: Additionally AC/DC Power Supplies with EU standard connectors

One kit will make a wireless link “out of the box” and feature easy access to all the modules I/O-pins.

The RCTools-MBUS contains PC software tools supporting Wireless M-Bus protocol modules.

The MBUS-CCT (Configuration & Communication Tool) helps you to work with your Radiocrafts modules. The program enables you to easily configure the module and can additionally work as a terminal window, where data can be sent or received to / from any serial port. The RSSI (Received Signal Strength Indicator) informs you about the Link budget and helps you estimate range.

What is Wireless M-Bus?

Wireless M-Bus is the only European standard for wireless meter reading (EN 13757). The standard was originally developed for communication with battery operated gas, water and heat meters, operating at 868 MHz with a focus on low power consumption and low implementation cost. The standard has later been updated and expanded to include narrowband radio, security (encryption and authentication), and repeater networks. It supports all types of utility meters as well as environmental sensors. Wireless M-Bus is the basis for OMS (Open Metering System) and other national companion standards for meter reading.
