Multi-Stack Technologies

Flexibility and quick reaction are key elements for modern and efficient IoT networks. With our Multi-Stacks, we provide an innovative solution for combining several communication technologies for wireless data transmission in just one stack. Switch between Wireless M-Bus and / or LPWAN technologies like mioty®, LoRaWAN® and Sigfox during runtime – perfectly adjusted to your requirements and done quite easily via our well-established Multi-Stack API. Therefore you can not only benefit from the different advantages and features of the relevant technology, but also save resources when only one stack integration is needed.

Why combine different technologies in one stack?

More network coverage

Not every radio network is available at every operation site. With the Multi-Stack you can easily choose between several wireless networks. Therefore the network coverage can be enhanced.

More Features

The advantages of different technologies are summed up, for example remote meter readout via the popular wM-Bus protocol and further data transmission over large distances via LPWAN technology.

more efficiency

If data should be transmitted via several radio technologies in the same network, you can do this by using different controllers - or you can save resources by using just one Multi-Stack.

Multi-Stacks: One integration for more flexibility!

Multi-Stacks architecture

The heart of our Multi-Stacks is the STACKFORCE Multi-Stack API, which enables the control of an optional number of stacks and switching between those during runtime. The Multi-Stacks can be operated inside (library version) or as (modem version) an embedded firmware for operation at a microcontroller or system-on-chip. The library version (object code) includes an example application and an example project for IDE and can be used in conjunction with an embedded operation system (OS) dedicated for microcontrollers,  while the modem version (firmware / binary) includes a serial interface and power management. Both versions come with the Multi-Stack and can be used.

Standard or customized?

We provide an increasing number of standard Multi-Stacks for the most common platforms. Nevertheless, we do not lose sight of your personal requirements. Our developers work with you at all times to customize Multi-Stacks according to your needs. Whether you need a special combination of two or more technologies or you want to use a platform not supported by our stacks so far, just tell us. We will find the perfect solution for your IoT project!


Standard Multi-Stacks

Standard Multi-Stacks

Our standard Multi-Stacks score with direct availability, well-established and proven source codes and easy integration. The most popular combinations our "big four", wireless M-Bus, mioty®, LoRaWAN® and Sigfox, are already available as dual- or triple-stacks for the most common platforms.

You will find a list of our currently available standard Multi-Stacks here.
