Sigfox operates a global low-power wireless network dedicated to IoT communication. Devices connect to the network using simple and secure protocols, and can send and receive small payloads of up to 12 bytes. The network uses ultra-narrowband radio technology for long range communication of over 100km while consuming very low power. Developers can choose from a variety of certified modules starting at $2 to connect devices to the Sigfox network and access cloud services for data collection and device management.

- 4. About Sigfox Sigfox is not selling chips Sigfox is not building connected solutions Sigfox has invented a radio protocol Sigfox operates a global network
- 5. About Sigfox IoT Communication Service Available in 36 countries as of Nov 1st Low Energy + Simplicity Chipsets from several major silicon vendors
- 7. Why Sigfox ? Need for a solution dedicated to the IoT, not an existing one tweaked for it. We only serve the IoT, that’s why we’re doing it efficiently
- 10. Hardware Sigfox is not a hardware vendor Ecosystem of established partners
- 11. Hardware Sigfox is not a hardware vendor Ecosystem of established partners & module makers
- 12. Modules Starting from $2 Offers combining Sigfox with Wifi , BLE, GPS Fast track for product certification Quite expensive for industrialisation Skills needed Ref.Designs Cheapest solution Skills++ needed Certification program

- 15. Building your own You can build your own, using one of the compatible RF transceivers (NXP, STMicro, TI, Semtech, SiLabs) Only interesting for huge volumes, retrofit or special requirements Will need full Sigfox certification program
- 16. Prototyping Arduino & Raspberry Pi kits available from various partners Check out http://partners.sigfox.com for the full details
- 17. Antenna Best way to ruin a great device is to mess the antenna integration Balance between design & performance Take into account from the early days of your project We’re here to help with experts !
- 18. Antennas ( small feedback) Antenna Price Size Integration Perf Indoor? External YES Internal wire YES Ceramics NO PCB printed YES
- 19. Communication
- 20. Core concepts
- 21. Simplicity No connection No configuration No pairing No signaling
- 22. Low Energy Years of battery life tens of mAmps while transmitting idle (µAmps) 99.x% Independent solutions Reduce maintenance & TCO
- 23. Properties Good indoor propagation Simple 2-way communication Long Range between emitter and receivers
- 24. Very Long Range Best case scenario +100km between transmitter & receiver (base station) Real life A few kms (city) to tens of kms (countryside), depending on the topography
- 25. Two-way communication Devices can receive updates sent from your application server Each communication is instigated by the device
- 26. Small messages Useful payload: up to 12 bytes Up to 140 times each day (contract) 100 bits/s
- 27. Less is more ! GPS coordinates (lat x lng) : 6 bytes Temperature: 2 bytes State reporting : 1 byte Heartbeat, update request : 0 byte Keep it as simple as possible
- 28. Keep it simple Useful payload up to 12 bytes No multimedia, no TCP/IP, no JSON, no XML … Get down to binary : 2^96 possible values Lightweight frames means shorter emission times
- 29. Security
- 30. Security No keys exchanged over the network, no handshake Messages can be encrypted or scrambled Each message is signed with a key unique to the device
- 31. Message Signature With each message, a hash is calculated & sent; using: Device ID Secret key, unique to the device. Never transmitted OTA Payload Internal increment
- 32. Radio properties Great tolerance to interferors Jamming resistant Interception is hard: UNB & frequency diversity
- 33. Jammers
- 35. Sigfox use The network currently monitors a 192KHz part of the spectrum Each message is ~100Hz wide
- 36. High capacity 192 KHz Each repetition is 100Hz
- 37. Anti-jamming capabilities due to UNB intrinsic ruggedness coupled with spatial diversity of the base stations (+20dB) High resilience to interferers 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.✓
- 38. Spectrum efficiency & capacity
- 39. Coverage
- 40. Global network Sigfox is offering a global network, not a solution to build private networks Roaming is included is the standard service Devices will work the same all over the network
