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
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 !
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
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
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
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.✓
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

44. Testing tools
• SDR Dongle
• End to End testing (not for prod)
• RSA (Radio Signal Analyzer)
• Included in SDR dongle
• Test radio compliance
• Litepoint analyzer IQxel-M
• RF testing (WiFi, BLE, Sigfox)
• Manufacturing tests
• Pre-certification
45. Geolocation - Atlas service
Network based geolocation, using reception patterns &
machine learning
Receive lat/lng through callback, with a few km precision
47. Get your data
View messages : Sigfox web platform
Get messages : REST API (pull)
Receive new messages : HTTP Callbacks (push)
48.
49. Callbacks
Each message received from your devices will be forwarded to
your application server(s)
Fully customizable HTTP requests
Used to send data back to the device as well
Easy integration with major Cloud solutions :
AWS, MS Azure, IBM, Samsung, SAP, theThings.io, Thingworx, …
50. Downlink messages
A downlink message can be
Semi automatic : sent directly by the network
Custom : sent by your own application server
