Wireless M-Bus Stack

Logo wM-Bus and OMS

The popular wireless M-Bus Protocol Stack by STACKFORCE leads to competitive products that are easy to install and maintain. The stack implements all protocol elements that are required for wireless M-Bus compliance and provides additional tool support. It is optimized towards a compromise of small footprint, excellent modularity and scalability, but though being feature-rich. Learn more about Wireless M-Bus technology!

STACKFORCE has partnered with multiple industry leading silicon vendors, thus the stack has already been ported to various platforms.

OUR Wireless M-Bus Stack ArchitecturE

Classical or with LPWAN technology

Our wireless M-Bus Stack is not just available as the standard version, compliant to EN 13757 or OMS specification as meter or collector, but also in combination with mioty® (M-Bus-over-mioty® stack) or LoRaWAN® (M-Bus-over-LoRaWAN® stack). Therefore you do not only benefit from the well-proven, well-spread and popular wireless M-Bus protocol, but also from the advantages of the modern LPWAN (Low-Power Wide Area Network) technologies. They enable larger transmission ranges, which is especially of interest for applications like Smart Metering and Smart City.

Beyond wireless M-Bus

Wireless M-Bus surely is the standard protocol for metering purposes. But wouldn't it be great to enhance the flexibility of your network and to be able to switch between wireless M-Bus or OMS and also LPWAN technologies like mioty®, LoRaWAN®, Sigfox and others? We make it possible!

Multi Stack

Our Multi-Stacks offer the possibility to choose between several stacks and radio standards, such as mioty®, LoRaWAN®, wireless M-Bus, OMS, Sigfox and others. This flexible solution allows you to achieve maximum usability when you connect your product to the Internet of Things (IoT).
