[2015] Sigfox basics

  1. 1. One network A billion dreams
  2. 2. About SIGFOX An operated communication network Dedicated to the | oT: low power / long range
  3. 3. Another communication protocol ? We already have plenty ! WiFi, Bluetooth Low Energy, GSM, Zigbee, .. No need for yet another technology !
  4. 4. Sure ? WiFi, BLE : Rely on a hub connected to the Internet. Short/ medium range Zigbee : Private networks GSM : High energy consumption (TX ~450mA) + Expensive
  5. 5. Quick video presentation 1?: WDRLDWILDE ROLL 0UT_*‘_~‘_ 1,2“ “-1._1‘/ ex’ 1/1_. =1_ https: //www. youtube. com/ watch? v=AiaGO| cB7zY 1’ omme version
  6. 6. Current coverage Nationwide coverage in France, Spain, Netherlands & UK Ongoing rollout in Portugal & US Test cities : Antwerp, Dublin, Milan, Munich, Graz, San Francisco, Seoul, Singapore,
  7. 7. Technology SIGFOX operates in the ISM bands (868/915 MHz) Sub-Ghz + Ultra Narrow Band Focus on energy efficiency rather than bandwith increase
  8. 8. SIGFOX specifics 12 bytes max per message 140 messages per day max Two-way communication
  9. 9. 12 bytes ! ? Yes, twelve bytes JSON, XML, .. forget it 12 bytes is 96 bits, meaning 2"96 values.
  10. 10. 140 messages per day ISM bands are regulated, and every device must respect a 1% duty cycle use 1% means 36 secs per hour A SIGFOX message takes up to 6 sec to emit ~6 messages per hour max
  11. 11. Hardware SIGFOX is not a hardware vendor Plenty of partners offering SIGFOX-ready solutions Adeunis, Atmel, Snootlab, ST, Telecom Design/ Avnet, Telit/ Rutronik, TI,
  12. 12. Getting started Arduino shields (Snootlab, Atmel) Dev Kits (Atmel, TD, Telit, Snootlab) Modules (Telit, TD, .. ) System on chip & RF transceivers
  13. 13. Getting started Protocol specifics are handled by embedded libs All you have to do is send commands over serial Either AT commands or higher-level methods provided by the solution enabler
  14. 14. Downlink communication When sending a message, you can request a downlink response In this case, your device will stay in Rx mode ~20 secs The downlink message can be set as a auto message (~ack) or be sent an instant response from your own SI
  15. 15. Where are my messages ? Operated network = don't deal with RF communication issues Once your message is sent & processed by the SIGFOX cloud, you can retrieve it using a REST API or an HTTP caflback Assume a few seconds between emission start & callback to your platform
  16. 16. Data pushed by callback You'll receive the raw payload you sent (up to 12 bytes of hex) And various metadata : deviceld, timestamp, the station which received the message, signal/ noise & rssi values
  17. 17. Callback handling - quick example http: //sigfox-callback-demo. herokuapp. com/ http: //github. com/ nicolsc/ sigfox-callback-demo
