Integrating Sigfox and LoRaWAN technologies has become a hot topic in the IoT world. This convergence can bring multiple benefits to stakeholders, including device manufacturers, IoT service providers, and end-users. But the biggest question is how to implement this dual mode in your IoT device or solution?
First, it’s important to understand the business value of Sigfox and LoRaWAN convergence. For device manufacturers, it means cost-effectiveness by accessing a wider market with a single SKU product. IoT service providers can expand their coverage with just one IoT device, while end-users can enjoy seamless connectivity in different geographies.
So, how do you make this happen? Here are the steps to follow:
Step 1: Pick a Compatible IoT Chipset
Choose a chipset that supports both Sigfox and LoRaWAN technologies. Some popular options are Semtech LR1110 and STM32WL5 from ST Micro, and Murata LoRaWAN modules.
Step 2: Integrate Open-Source Sigfox & LoRaWAN Firmwares
Integrate the Sigfox end point library and the LoRa Basics Modem stack for Semtech chipsets. You can also enable Sigfox on LRxx Semtech chipsets. By the end of 2023, Semtech will release the Sigfox implementation scheme on their SX12xx chipsets on GitHub.
Step 3: Integrate, Certify, & Test
This step involves adapting the chipset to your selected microcontroller, obtaining radio and protocol certification, managing device credentials, and integrating and testing the device.
Step 4: Update the Device Application Firmware
Update the device application firmware to enable the best technology selection scheme for your use case. This means either choosing the best available network connectivity at the provisioning phase for static devices, dynamically choosing the best connectivity for mobile devices, or connecting Sigfox and LoRaWAN concurrently to increase network capacity and resilience.
By implementing these steps, you can successfully converge Sigfox and LoRaWAN in your IoT device or solution. This will not only bring cost savings but also expand your network coverage and increase network performance and resilience. Consider leveraging smart network technology selection on edge or in the cloud to further optimize your connectivity.
