The document summarizes a Sigfox workshop held at Euratechnologies in April 2018. It provides an overview of Sigfox, its global low power wide area network, and how it can be used for applications like parking management, asset tracking, home alarm systems, and stolen vehicle recovery. It also discusses Sigfox's ultra narrow band technology, random access protocol, and other technical aspects. Finally, it demonstrates how to get started with the Arduino MKRFOX1200 kit for prototyping Sigfox devices and transmitting messages over the network.

- 5. CONFIDENTIAL 5 Parking space management • Improve parking policies • Obtain turnover information in real time • Guide drivers more efficiently • Have greater control over special permit spaces • Save resources through fast implementation • Decrease costs through easy maintenance • Generate additional revenue • Decrease CO2 emissions Fastprk is an intelligent Parking Management System that allows cities and operators to manage parking resources more efficiently and parking operators to generate additional revenue. Fastprk offers information about parking availability to the drivers within blue and green spaces, and also on loading, taxis and disabled parking bays Problem solved Optimize parking spaces in the city BenefitsSolution LIVE
- 6. 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
- 7. Home Alarm System CONFIDENTIAL 7 Alarms are traditionally connected through GSM to central system and burglar intrusion can be facilitated by GSM jammers. There is a need for effective backup connectivity to ensure more robust alarm transmissions. ▪ Robustness of solution is a commercial differentiator ▪ Continuity of service ▪ Soft deployment via over the air update - no HW swap. No user impact ▪ Network available to handle millions of devices Sigfox has upgraded Securitas Direct’s alarm systems to provide a back-up connectivity in case jamming is detected. The upgrade was possible over the air as a Sub-GHz chip was already inside. Challenge BenefitsSolution Alternative partners for this application LIVE
- 8. Stolen Car Recovery CONFIDENTIAL 8 Locate and recover stolen assets through a small and discrete GPS tracking device. ▪ Peace of mind that assets can be tracked or recovered ▪ Complete solution with added services ▪ No jamming Small sensor : 2/3 of the size of a cigarette pack Connected with the Police 24 hours / 7 days Autonomy : 3 to 5 years of use Internal antennas (UHF and GPS) Tracking through GPS and UHF Geo-localization active in underground carparks Challenge BenefitsSolution LIVE

- 12. RANDOM ACCESS CONFIDENTIAL 12 Unsynchronized transmission between the network and the device The device transfers a small amount of energy on a random frequency with no protocol overhead (frequency hopping) SIGFOX Base stations permanently listen to the spectrum and interpret received UNB signals The same frame is sent 3 times enabling time and frequency diversity Frame1 @F1 Frame2 @F2 Frame3 @F3 Uplink message t1 t2 t3 2.08s for 12B payload Frequency Time ✓ ✓ ✓ ✓
- 13. CONFIDENTIAL 13 Anti-jamming capabilities due to UNB intrinsic ruggedness coupled with spatial diversity of the base stations (+20dB) HIGH RESILIENCE TO INTERFERERS robust to operate in the public ism band For the same technical reasons as above, UNB is extremely robust in an environment with other spread spectrum signals. However, Spread spectrum networks are affected by UNB signals. Ultra Narrow Band is therefore the best choice to operate in the public ISM band 8 dB needed for the signal to be received Jamming signal ✓ ✓ Interference impact

- 19. Antennas • Lots of providers on shelves (Molex, Pulse, Linx..) • Can do your own • All depends on what you have & need! • Sens’it antenna: open source design https://build.sigfox.com/antennas#antenna-design-example
- 20. Antennas ( small feedback) Antenna Price Size Integration Perf Indoor? External YES Internal wire YES Ceramics NO PCB printed YES
- 21. Batteries • Sigfox predictability: no signaling, 1 message = X uAh • Different types of batteries = Different Use Cases Rechargeable device? Size constraints? Radio Zone has little impact on battery life • Peak current while transmitting 20 to 50 mA in Europe, 130 to 250 mA in US Coin cell: short lifetime Can work with extra (super)- capacitor circuit Prefer multiple smaller batteries over a big one
- 22. Radio zones • RZ1: Europe, MEA 868 MHz, +14 dBm • RZ2: North America, Brazil 902 MHz, +22 dBm • RZ3: Japan, Korea 920 MHz, +14 dBm, LBT • RZ4: South America 920 MHz, +22 dBm
- 23. Multi radio zones devices • Hardware Single Zone Different Hardware (modules) Different module version but same pinout/PCB • Hardware Multi Zones Same Hardware, stay in the same zone Set zone during production/firmware flashing • Software Multi Zones: Monarch service Same hardware, moving interzone For specific worlwide asset tracking use cases Require specific Sigfox firmware on module (more information coming soon)

- 37. Message received ? http://backend.sigfox.com (check your e-mails to get credentials) Navigate to the devices menu in the top bar Click on the ID of your device Enter the messages menu from the left navigation column
- 39. Callback setup Device Type menu Click on your device type name Enter the Callbacks menu Select new default callback
- 44. Callback status In the Devices > Messages panel, you have a indicator of the callback status (an arrow) Black : in progress Green : Callback OK Red : Callback KO (at least one of the callbacks failed) Click the arrow to display details.
- 46. Frame parsing
- 47. Sigfox payload display feature Using a « simple » grammar, you can ask Sigfox to parse your incoming data This is done at the device type level
- 50. Parsing the Hello World sample Modify the sketch to send 3 values in a same message short valA = 7700; short valB = 128; float valC = 654.32; SigFox.beginPacket(); SigFox.write(valA); SigFox.write(valB); SigFox.write(valC); SigFox.endPacket();

- 52. To go further… Retrieve module internal temperature and use custom grammar to display real value (check https://www.arduino.cc/en/Reference/SigFox and internalTemperature() function)
- 54. How does it work? Downlink flag included in Sigfox message 20 sec after first frame transmission, the module wakes up and waits for downlink response (25 sec window)
- 55. Downlink Callback setup Automatic callback: Device Type > Informations > Edit Set Downlink mode to DIRECT Enter an 8 bytes value
- 58. Sample code Simple change SigFox.endPacket(); to SigFox.endPacket(true); This will request a response from the network
- 59. Handle the response https://github.com/nicolsc/mkrfox-downlink void loop(){ while (SigFox.available()) { Serial.print("0x"); Serial.println(SigFox.read(), HEX); } }

- 67. Sigfox Platform https://github.com/luisomoreau/sigfox-platform Open source platform maintained by 2 Sigfox employees Display devices and messages in a user-friendly dashboard Still in active development, not for production, bugs will happen ☺ You can contribute!
- 68. Sigfox Platform – Getting Started 1. Register on demo platform: https://workshop.iotagency.sigfox.com/ 2. Create your Developer Token (Connectors => Manage Tokens) 3. Still in the connectors page, select BIDIR callback and copy/paste details in a new Sigfox custom callback
- 69. Sigfox Platform – Getting Started Hurray ! You have set up a custom callback. Now send a Sigfox message and see what happens on the platform: - the device must have been created - messages now appear in real time
- 70. Sigfox Platform – Going Further Well, it's nice to see hexadecimal payload messages but what if I want to see intelligible data? 1. Head over to: https://github.com/luisomoreau/sigfox-platform/wiki/Adding-a-custom-parser 2. Create a parser in the "Parsers" platform section 3. Link your device to it ("Devices" => "Edit" => Select your parser) 4. That's it! You should now see decoded messages on the platform!
- 71. Sigfox Platform – Going Further Okay, but now what? Once your device messages can be decoded, you can create custom dashboards and widgets. Have some fun trying to configure geofencing alerts, tracking widgets and more. And feel free to share your device on the organization created for this workshop, so others can see what you are building!
