Thanks to a reliable, robust process, this system can transmit data from several hundred thou- sand sensors over long distances securely, efficiently and with low power consumption. It is ideally suited to applications such as remote monitoring of large industrial facilities, buildings or company grounds as well as to smart city solutions. MIOTY is a hardware-independent software solution that was incorporated into the European Telecommuni- cations Standards Institute (ETSI) standardization for low-through- put networks. Many branches of the IIoT are concerned with reli- able condition monitoring of fa- cilities and production processes and with predictive maintenance. These issues have been particular- ly hard to deal with to date in the complex environments of indus- trial facilities and outdoors. With MIOTY technology from Fraun- hofer IIS, based on a patented telegram splitting method, this is about to change: the technology guarantees interference-resistant wireless data transmission for several hundred thousand sen- sors and reception across several kilometers at a gateway. MIOTY can be (retro)fitted in commercial and industrial environments, and the network density can be gradu- ally increased with additional sen- sors. Thanks to a software-based technology approach, it can be used in conjunction with various hardware components, such as commercially available sub-GHz transceiver chipsets. Thanks to en- ergy-efficient transmission tech- nology, this low-power wide area network (LPWAN) guarantees long service lives for the sensors. Using the free 868 MHz frequen- cy band, data is sent in a star to- pology directly from individual nodes to the central base station. Usually, only small amounts of data – e.g. temperature readings – need to be transmitted; this can be done extremely energy efficiently. MIOTY was designed specifically for what are known as massive IoT applications involving several thousand small end devic- es, for example to enable efficient remote maintenance of plant and equipment.
