SoC integrates Fraunhofer mioty-LPWAN and IoT protocol
The standardized Fraunhofer mioty protocol stack for Low Power Wide Area Networks (LPWAN) and IoT applications is implemented and tested in the newly introduced wireless bidirectional sub-GHZ SoC (System on Chip) Series 2 platform EFR32FG23 (FG23) from Silicon Labs. The single-die, multi-core SoC presents extremely 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 optimize processes in 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 generation IoT standard mioty and its Telegram splitting. Mioty as a software solution is now also available in the latest SoC from Silicon Labs.
First test measurements for real IoT applications demonstrate an extremely 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 exceptionally very low: For a downlink receive sensitivity the FG23 Advantage implementations provide 5 dB more sensitivity compared to the predecessor chip, and it goes along with a reduction of the transmit current (at 14 dBm, at 3.3V) of 30% less current draw.
