LoRa® Wide Area Network (IoT)

The "Internet-of-Things" (IoT) is a popular term from the communication technology world. Information from miniaturised sensors (things) are collected worldwide over the internet and provided on private and public cloud-systems. This opens up new fields of service and business.

To transfer information secure and reliable, different communication technologies are available. One of these technologies used by Sotronik is the LoRa® Wide Area Network that offers several advantages compared with other technologies:

  • up to 15km range
  • small infrastructure costs
  • internet connection with LoRaWAN® possible
  • reliable transmission (not GSM-network-dependant)
  • low-cost and low-power technology (very long battery runtime possible)
  • encrypted, bi-directional transmission (suitable for sensor- and actuator systems)
  • uses international, free frequency band (i.e. 868MHz band in Europe)
  • private network operation possible (alternative to the public LoRaWAN®-network-provider)


Due to huge know-how and experience from already done IoT-projects, Sotronik can provide optimal support for the realisation of IoT-products.

Remote control systems (from the device to the visualisation)

Sotronik implements customer-specific remote-control systems that can be operated based on secure Internet connections, with or without additional devices (gateways).

In several projects, Sotronik has integrated the necessary communication software directly into the existing customer firmware, thus realising a solution that generates no additional costs per device and can be operated with very high performance.

Where direct integration into an device is not possible, Sotronik implements the communication software into the firmware of OEM gateways.

Systems and devices with an integrated Sotronik solution can thus be accessed via customised smartphone/tablet APPs (OS independent) and via standard web browsers for PCs.

Sotronik offers part- and complete solutions, covering all necessary parts from the device firmware, to cloud- or company-web-servers onto APP or browser visualisations. We distinguish here between remote control systems without and with a central web server ("Data Hub").

Direct remote access (without web server centre)

With the cloud solution of our IoT partner nabto, we provide our customers with secure, direct and therefore high-performance remote access to their devices and systems. The nabto remote access works without an intermediate data server and is therefore particularly low-maintenance and cost-effective.

User administration can be realised directly on the end device via an intelligent pairing procedure. This means that the solution does not require central user data storage and thus complies with all applicable data protection regulations without further intervention.   

Indirect remote access (with web server centre)

This solution is favoured by customers who are interested in the central collection of device data and also want to offer their end customers remote internet access. In this case, the web server centre acts as a "data hub" and also contains the user administration.
