This document provides an overview of a SIGFOX event held in Madrid on November 25th, 2015. It introduces the presenters and provides details about SIGFOX, including that it has invented a radio communication protocol and operates a global network. It discusses SIGFOX's core concepts like energy efficiency, long range, and low bandwidth communication. Examples of use cases like smart cities and predictive maintenance are also mentioned. The document concludes with a demonstration of connecting an RFID reader to SIGFOX and instructions for getting started with the SmartEverything prototyping board.
![Getting started
• Plug the SmartEverything board using a micro USB cable

SIGFOX Makers Tour - Madrid
- 1. #6 Madrid — 25.11.2015
- 2. Program • Slides • Demo(s) • Workshop • Fun
- 3. Us Nicolas Lesconnec Developer & Maker Evangelist Anthony Charbonnier Startup Relations Manager Jon Regueiro Support Engineer
- 4. ABOUT SIGFOX
- 5. About SIGFOX • SIGFOX has invented a radiocommunication protocol • SIGFOX is operating a global network • SIGFOX does not sell hardware components • SIGFOX does not build connected solutions
- 6. New possibilities • Direct Internet connection. • No battery drain. Years of autonomy. • Detect. Send. Receive. • No configuration
- 7. In a nutshell • Power on • Send a message • It’s picked up by n of our base stations • Instantly forwarded to your own server • That’s it
- 8. Complexity • AT$SF=0123456789 • No pairing or configuration of any kind • HTTP request to your server
- 9. Proof
- 10. Why SIGFOX • Hub-based technologies are not compatible with independent devices • Need for a protocol designed for the IoT, and not one tweaked to address it.
- 11. Core concepts • Energy efficiency • Very Long Range • Out of the box connectivity • Outdoor + Indoor • Two-way communication • Low bandwidth, small messages • Ultra Narrow Band
- 12. Energy efficiency • Tx : ~25/30 mA for a few seconds • 99.x% of the time, device is silent • Idle consumption is key • Idle : a few µA
- 13. Very Long Range • Countryside : Tens of kms • Cities : A few kms • Direct line of sight : wow !
- 14. Out of the box • Network is serving the devices, not the other way round • Device simply sends a frame, message is detected by n base stations • Message is validated / deduplicated by our backend
- 15. Outdoor + indoor • 868MHz has good propagation properties • Radio waves are not magic • Consider ~20dB of attenuation indoor, and ~30dB for light underground or tricky buildings
- 16. Two-way communication • Send updates to your device(s) • Default behaviour: wake up, send, back to sleep • No passive Rx mode • Device can receive a message upon request • Every communication is instigated by the device
- 17. Low bandwidth • 100 bits / s • 12 bytes per message
- 18. 12 bytes !? • Yes. Seriously. 12 bytes. • This is the available payload. • You can put a lot of info in 96 bits • 2^96 is a 30ish-digit number. • 8 billions of billions of billions of possible values
- 19. Payload examples • Full GPS Coordinates : 6 bytes • Temperature : 2 bytes • State reporting : 1 byte • Hearbeat, update request : 0 byte
- 20. How frequently ? • 140 times a day
- 21. 140 times / day • Not a technology limit • Compliant with the European regulation: 1% duty cycle
- 22. Money • Most pricey subscription: €14/year • A couple of devices, 140 messages/day • The higher volume, the lower the price • The lower number of messages, the lower the price • Down to €1/year for large volumes & a couple of messages/day • Startup plan : €8/year, as if already 30k devices.
- 23. Security
- 24. Security • Each device is identified by a unique ID on the network • Each message is signed • Servers managed by ourselves, in 2 french datacenters. • Security is never finished, permanent effort.
- 25. Signature • Each message is accompanied by an hashed signature, made from : • the device id • the device PK (unknown to the user) • the payload • internal increment
- 26. Signature • Replayed messages • Altered messages • Spoofed messages
- 27. Encryption • By default, the payload is not encrypted • Encryption cost a lot of energy • No « one size fits all » solution. • Up to you to use the encryption most suited to your case
- 28. Radio properties • Great resistance to interferors • Very difficult to jam • Interception is hard • UNB • Unpredictable frequency
- 29. Radio properties
- 31. Ultra Narrow Band • The SIGFOX protocol relies on the Ultra Narrow Band technology • A message : ~100Hz wide • Each base station watch a 200KHz part of the spectrum • Hard part: detect message without knowledge of the precise frequency or schedule
- 32. Ultra Narrow Band • Why Ultra Narrow Band ? • Easy analogy : cars vs motorbikes
- 35. Message received
- 36. Frequency used • SIGFOX uses unlicensed sub-GHz bands : • 868MHz in Europe • 902MHz in the US
- 37. Unlicensed != unregulated • SIGFOX complies with both ETSI (Europe) & FCC (US) regulations • ETSI : 1% duty cycle • FCC : duration of emission
- 38. Coverage
- 39. Global network • Roaming is included in the basic subscription • Your device can switch from one country to another without additional charges.
- 40. Current - Nationwide • France • Netherlands • Spain • UK
- 41. Current - cities • Bogota • Dublin • Milan • Munich • Santiago • San Francisco • …
- 42. Rollout in progress • Belgium • Denmark • Italy • Luxembourg • Portugal • USA

- 47. Use cases
- 48. IoT != Connected gadgets Sexy Stuff BORING BUT USEFUL IOT
- 49. Good use cases • Not that talkative devices : small messages every now and then • Independent devices
- 51. Smart City
- 52. Ifttt-like • Press the button, send an empty frame & trigger any pre determined action • « Mom I’m home ! » • « Get me a taxi» • Replay last order, ~Amazon Dash

- 55. You ? • You can build a PoC very quickly • Lot of funny stuff to make • And lot of $$$ to make too ;) • KISS, dumb device means: • Cheap • Less prone to failure
- 56. Hardware
- 57. Hardware SIGFOX • SIGFOX is not a hardware vendor • Many established partners offer SIGFOX-ready chips: Atmel, TI, Silicon Labs, Axsem, Atim, … • Most Sub-GHz radio transceivers are compatible, it’s just about a software upgrade.
- 58. Prototyping • Arduino : Snootlab, SmartEverything • Raspberry Pi : Yadom • Can be bought one unit a time • Get started within minutes • Not for industrial use
- 59. Modules • Easy to work with : AT commands • Price range from ~10 to 20€ • Evaluation boards available from manufacturers : Adeunis, Telecom Design, Telit, ..
- 60. SoC, transceivers • Texas Instruments, Atmel, SiLabs, Axsem, .. • Cheap, a few $ • More complex to work with if not familiar • Certification needed if you don’t stick to the provided ref design.
- 61. Antenna • Critical when doing radio • 868MHz -> best case is 17cm (lambda/2) • Helicoidal, patch, … antennas possible.
- 62. Cloud
- 63. Get your data • Part of the standard service. • 3 ways • View - website • Pull - HTTP API • Push - HTTP Callback
- 64. Common use case : push callbacks • Get notified each time of your devices send a message • Can trigger whatever you want : alarm, notification, data processing, … • Example here: http://github.com/nicolsc/sigfox- callback-demo
- 65. Set up a callback
- 66. Downlink • Message sent to a device can be • Automatic with a pre configuration • Sent from your own server
- 67. Downlink auto • Simply set what message you want to send back • Hardcoded • Time, Station ID, .. for sync purposes
- 68. Downlink callback • Same mechanism than the uplink callback • Set up an URL • An when called, send your 8-byte frame within the response body
- 70. Real demo
- 71. Connected RFID reader • Standard 125KHz RFID reader & tags • Once a tag is detected, send its ID through SIGFOX • Update a live dashboard • Do something else :)

- 86. Downlink
- 87. How does it work ? • The Module send the frame, then sleep for 20s • Then it enters Rx mode • Waits 20s for a response • Quits Rx mode & goes to deep sleep
- 88. Request a downlink • Use the AT$SF command, with an additional parameters • AT$SF = [hex byte]*, 2, 1
- 89. Set up the downlink
- 90. Handle the response • When entering Rx mode, the module will display • +RX BEGIN • Received frame will be displayed as • +RX=[hex byte] [hex byte]… • When leaving Rx mode, it will display • +RX END
- 91. Handle the response • Detect an input line starting with +RX= & parse it as a series of hex bytes • If no downlink message has been sent, you’ll have no +RX= line, just the BEGIN & END flags
- 92. Sample input/output AT$SF=55 50 4c 49 4e 4b, 2, 1 OK +RX BEGIN +RX=44 4f 57 4e 4c 49 4e 4b +RX END
