Devtalks Cluj - Develop geolocation solutions with Sigfox
1 like299 views
Sigfox is a global IoT network that provides low-power, low-cost connectivity for remote devices to send small amounts of data over long ranges using radio signals picked up by antennas and transmitted to servers; various geolocation techniques can be used with Sigfox, including signal triangulation, combining with other technologies like GPS, WiFi access point sniffing, and internal storage to record location when outside coverage; examples are provided of tracking containers across the world and monitoring industrial assets using Sigfox with GPS or BLE for indoor and outdoor geolocation.
Devtalks Cluj - Develop geolocation solutions with Sigfox
- 1. Aurelien Lequertier @aureleq Building optimized geolocation solutions with Sigfox
- 6. Sigfox: Global IOT network Low power, to provide autonomy Global, to be used everywhere Low cost, to address everything Easy to use, and adopted quickly
- 8. An object emits a radio message Our antennas pick this message We transmit this message to your server
- 10. 1 % duty cycle for Objects Up to 6 messages/hour UPLINK 12-Byte payload - Sensor data - Event status - GPS fix - Application data DOWNLINK 8-Byte payload - Action / actuator trigger - Device management - Application parameter setting 10 % duty cycle for Base Stations 4 guaranteed downlink msg/day SIGFOX CLOUD SMALL MESSAGES to answer the cost & autonomy constraints of remote objects
- 11. Tracking a container across the world
- 12. What would be your default choice?
- 13. What would be your default choice?
- 14. Sigfox geolocation Signal level triangulation by gateways No additional hardware on device Location retrieved on Sigfox cloud (http(s) callback, email) Km accuracy
- 18. There is a wide variety of Real Time Location Systems

- 20. How it works? WiFi AP sniffing WiFi access points database (Google, Here) 10-50 meters location Ideal in urban environment Requires 2 MAC addresses … and 2 MAC addresses = 12 bytes ☺
- 21. Example code with Pycom SiPy
- 22. Sensolus offers an end-to- end tracking solution. It notifies Airbus about its assets’ trips and give insights on supply chain optimization. The device embeds an internal memory to record data when outside of coverage. Problem solved Track spare parts between the headquarters and the sites of its suppliers BenefitsSolution ▪ Cross country tracking without high roaming fees ▪ Real-time visibility on the asset during transportation ▪ Automation of the supply chain Industrial asset management GPS + BLE tracker for indoor and outdoor geolocation LIVE
- 23. Combining with GPS Sigfox + GPS work well together Lat and Lng coordinates can be coded on 6 bytes total IE: 46.7634899 23.5591701 4th decimale: ~ 10 meter precision 2 million possible values 3 bytes = 2^24 (16 millions)
- 24. Improving GPS battery consumption Containers tracking => 1 msg/hour, 1 msg/10 min? Cold start drains battery! Move positioning algorithms to cloud, ie Ubiscale.com => reduces cold start < 10 sec Extract from U-Blox Neo M8 datasheet
- 25. All in One module Wisol module including: • Sigfox • GPS • BLE • WiFi • Accelerometer GCC compatible, code on: https://github.com/yepark-wisol/WSSFM20Rx_12x
