Energy Harvesting and Positioning for MIOTY® Technology

Wireless MIOTY® transmission technology is used for massive IoT applications in the Industrial Internet of things (IIoT) or in smart city applications and transmits data from several hundred thousand sensors reliably and robustly even over large distances. This is made possible by the patented telegram splitting method developed at Fraunhofer IIS. MIOTY® is a hardware-independent software solution used in an ETSI-standardized form – especially for low-power wide-area networks (LPWANs) – and is available under license for integ- ration into a variety of customer solutions. It is also possible to create a self-sufficient power supply for MIOTY® sensors using energy harvesting technologies. Indeed, we have developed solutions that generate power by exploiting minimal vibrations or temperature differences, which is particularly beneficial when it comes to operating several hundred or thousand sensors self-sufficiently and in an energy-efficient manner over a period of several years.

The field strength-based positioning technology locadis can be incorporated in order to determine the position of sensors in massive IoT networks. This enables indoor and outdoor positioning within a MIOTY® network using only the infrastructure (base stations) and the sensors connected to the MIOTY® technology.
