How Wireless M-Bus works in a Smart Metering Network
A typical Wireless M-Bus smart metering network consists of smart meters, a Wireless M-Bus communication link and a gateway or data collector.
The meter periodically transmits consumption and status information over Wireless M-Bus. A gateway forwards the data to the utility’s system.

Wireless M-Bus For Smart Metering FAQ
What is Wireless M-Bus and why is it used for Smart Metering?
Wireless M-Bus is a standardized wireless communication protocol specifically designed for remote meter reading. Based on the EN 13757 standard, it provides reliable, low-power, and secure communication for electricity, gas, water, heat meters, and heat cost allocators. It is particularly well suited for battery-powered meters that need to operate reliably for many years.
What types of smart meters can Radiocrafts Wireless M-Bus modules be used with?
Radiocrafts’ Wireless M-Bus modules for Smart Metering can be integrated into a wide range of utility meters, including water, gas, electricity and heat meters, as well as heat cost allocators.
Different module variants are available depending on the meter interface, frequency, communication requirements, and target market.
Why should I use a Radiocrafts Wireless M-Bus module instead of designing the RF solution myself?
Radiocrafts modules integrate the radio hardware and Wireless M-Bus protocol functionality into a ready-to-integrate solution. This significantly reduces RF development, protocol implementation, testing, and certification effort, helping manufacturers lower development risk and bring new smart metering products to market faster.
Which Wireless M-Bus frequency bands does Radiocrafts support?
Radiocrafts offers Wireless M-Bus modules for Smart Metering solutions across multiple sub-GHz frequency bands, including 169, 433, 865, 868, 915 and 923 MHz, depending on the module family and target region.
This allows manufacturers to select a solution suited to regional regulations and application requirements.
Which Wireless M-Bus modes do Radiocrafts modules support?
Radiocrafts’ portfolio supports major Wireless M-Bus operating modes including S, T, C and N modes, with support depending on the selected module family.
This enables solutions ranging from conventional 868 MHz smart metering to narrowband 169 MHz applications requiring greater range and penetration.
Can Wireless M-Bus reach meters installed in basements, meter cabinets, or other hard-to-reach locations?
Yes.
Sub-GHz communication provides better penetration than higher-frequency wireless technologies, making Wireless M-Bus suitable for many indoor and difficult metering installations.
For particularly challenging locations such as deep basements, pits, or underground water meters, Radiocrafts also offers 169 MHz Wireless M-Bus/Wize solutions, designed for long range and strong penetration.
How do I connect a Radiocrafts Wireless M-Bus module to my meter?
Radiocrafts’ standard Wireless M-Bus modules provide a UART interface for communication and configuration, simplifying integration with the meter’s host controller.
Radiocrafts also offers application-specific module families, including MPC pulse-counter modules and MSM sensor-interfacing modules, for applications where additional functionality can be handled directly by the RF module.
What is the difference between Radiocrafts' standard MBUS, MPC and MSM module families?
The standard MBUS modules provide an embedded Wireless M-Bus stack for integration into smart meters and data collectors.
MPC modules add autonomous pulse counting and scheduled transmission functionality, making them suitable for meters with pulse outputs.
MSM modules include intelligent sensor-interfacing functionality and can read and report sensors without requiring an additional external microcontroller for those tasks.
Are Radiocrafts Wireless M-Bus modules pre-certified?
Radiocrafts offers CE pre-certified Wireless M-Bus modules for applicable European frequency bands, helping reduce the certification work required when developing a finished smart meter.
Regional compliance varies by module, so manufacturers should select the appropriate module according to the frequency band and target market.
