Wireless Solutions by IMST GmbH

Your One Stop Shop for wireless. Wireless Solutions is the core competence of IMST GmbH. We offer easy-to-integrate radio modules for licence-free frequency bands 169/433/868/915/923 MHz and 2.4 GHz as well as comprehensive design services: from feasibility study, through prototyping and certification, to mass production.



LoRa® (abbreviation for Long Range) is a chirp spread spectrum (CSS) modulation technique developed by Semtech®. It is a physical layer that provides robustness, high range communication and low power consumption suitable for IoT applications. An essential feature of LoRa® modulation is the decoupling of bandwidth and bit rate. By means of a spreading factor for the band spread, the ratio between bandwidth and bit rate can be adjusted.

LoRa® modulation technique is available within a lot of IMST’s radio modules for different frequency bands (433/868/915 MHz and 2.4 GHz). Due to the high sensitivity on the receiver side, large communication ranges can be achieved. LoRa® modulation can be used in a huge variety of applications.

The LoRaWAN® is an open specification for a low power wide area networking (LPWAN) protocol. It is designed to wirelessly connect battery driven devices to the Internet in regional, national or global networks. The specification defines the device-to-infrastructure of LoRa® physical layer parameters and the LoRaWAN® protocol, and provides seamless interoperability between devices.

The LoRa Alliance® is a non-profit association and drives the standardization and global harmonization of the LoRaWAN® protocol.

To estimate Wireless signal ranges is not easy at all. LoRaWAN® claims to support a long range capability and low power. 10 kilometers (LoS) and more are often mentioned. In real life the range highly depends on several factors like antenna performance, output power, spreading factor, bandwidth, surrounding environment…

However, the easiest and fastest way to get an idea about the range and data rate that can be achieved use our Starter Kits. Get a Starter Kit and do your own range/packet error tests!

Our partners have developed devices based on our LoRa® solutions for a huge range of applications like agriculture, metering, street lighting, security, environmental sensor…
