Wireless M-Bus Products

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 also the flexibility to choose between different modes and frequency bands depending on application and geography. Radiocrafts is a leading provider of Wireless M-Bus solutions, and takes actively 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 cover 868 MHz, as well as variants at 433, 865, 869, and 815/923 MHz. The RC17xx series cover 169 MHz. The module can be configured to operate as Slave (in the meter), Master (in the concentrator), or as Repeater (single hop).

The modules have 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 at 868 MHz, and several km at 169 MHz. Ultra low power mode extends battery lifetime.

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

What is Wireless M-Bus?

Wireless M-Bus is the only European standard (norm) 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 (France, Italy, Netherlands) for meter reading.
