The standardised Fraunhofer mioty protocol stack for low power wide area networks (LPWAN) and IoT applications is implemented and tested in the wireless bidirectional sub-GHZ SoC Series 2 platform EFR32FG23 (FG23) from Silicon Labs.
The single die, multi-core solution presents low transmit and receive radio power together with robust RF performance and deep indoor penetration.
The bidirectional chip enhances the efficiency and performance of a wide range of IoT applications. New functions such as configuration of device settings and message acknowledgements optimise processes. These include building management, smart city applications, and Industrial IoT implementations.
The mioty protocol provides robustness based on its telegram splitting and energy-efficient communication. Mioty can be used in parallel to any other communication technology thanks to its interference-resistance.
The more IoT applications there are in the field, the higher the requirements for wireless connectivity. That means high ranges, high numbers of sensors for ’massive IoT’, low energy consumption, reliable and robust transmission, even in challenging wireless environments. This is solved by the next-gen IoT standard mioty and its telegram splitting.
Mioty as a software solution is now also available in the latest SoC from Silicon Labs: the EFR32FG23 (FG23).
Compelling results
First test measurements for real IoT applications demonstrate a high receiver sensitivity especially for the downlink of the chipset. Compared to the predecessor chip EFR32FG14, a significant increase in sensitivity is achieved. Likewise, the transmit current is low. That will underline that with the mioty integration a powerful SoC technology can moreover be maxed out.
“Due to the extremely high sensitivity, up to 80% more range is possible in line of site conditions. Even remote sensors or actuators e.g. in basements or deep indoor applications can now be reached,” explained Günter Rohmer, Head of the Fraunhofer IIS Research Division Positioning and Networks.
“The low power consumption of mioty in a SoC solution also enables battery lifetimes of more than 10 years or reliable operation from energy harvesting”.
Silicon Labs are a member of the mioty alliance. The technological leap in their sub-GHz solutions naturally opens up new possibilities for IoT applications.
Wireless hardware combo
“The combination of mioty and our wireless hardware will enable high-performance and secure connectivity for IoT devices. The very compelling test results by Fraunhofer IIS, verifies how our FG23 platform enables IoT end nodes to achieve 1+ mile wireless range while operating on a coin cell battery for 10+ years,”. Said Ross Sabolcik, VP/GM of Industrial & Commercial IoT Products, Silicon Labs.
“Low-power, long range, and security are fundamental requirements in the rapidly expanding IoT deployments of IIoT, smart cities, and smart buildings.”
