What is Sigfox ?

Sigfox is a radio solution committed to giving voice to the physical world thanks to our dedicated network. We provide an inexpensive, reliable, low power solution to connect sensors and devices. The Sigfox protocol focuses on : 

  • Autonomy - Extremely low energy consumption for years of battery life
  • Simplicity - No configuration, connection request or signalling, up and running straight out of the box
  • Cost - From the hardware used in the devices to our network, we optimize every step to be as cost effective as possible
  • Small Messages - No large assets or media, only small notifications
  • Complementarity - Due to its low cost and ease of configuration, Sigfox can be used as a secondary solution to any other type of network eg: Wi-Fi, Bluetooth, GPRS, etc.

Understand Sigfox technology

Access the Sigfox service

Working with Sigfox is very easy since everything you need is included in the service we offer. Our subscription service is based on devices connected to the network. 

Contracting with a Sigfox Operator grants access to our public network and to the Sigfox Cloud, where you will be able to see and manage all your devices on the network. It will also give you access to our support platform, for easy troubleshooting while developing your product, available 24/7.

For more information, please contact your local Sigfox Operator.  

Network overview

The life cycle of a Sigfox message is always the same  :

  1. A device wakes up and emits a message 
  2. Multiple Base Stations in the area receive the message
  3. Base Stations send the message to the Sigfox Cloud 
  4. The Sigfox Cloud sends the message to our customer's backend platform

It's that simple!

What is a Sigfox "Base Station"? 

Deployed in the field by our local operators, Base Stations are composed of three major elements :

  • An antenna to receive messages over the air, usually deployed on high points or towers
  • A LNA or LNAC to amplify the signal and filter noise
  • An "access point" which understands these messages and sends them to the Sigfox cloud 

Once interconnected with the Internet, they become part of our public network and start listening for all Sigfox messages which are sent by devices in the vicinity. 


Sigfox is a public network, meaning devices will rely on the infrastructure deployed by the local operator to communicate. Full public coverage can be found here: https://www.sigfox.com/en/coverage

In addition to our public offer, we have also developed a range of solutions to cover all of our customer's needs:

If you are located in a Sigfox deployed country but not yet covered, you can rent base stations through our Connectivity As A Service offer (CaaS). You can host your own access point and extend the SIgfox network in a flexible, cost-effective and simple way. Please contact your local operator to access these offers. 

If you are a device maker located in an area where Sigfox is not yet present, you can buy a Sigfox SDR Dongle, which will allow you to emulate a local version of the Sigfox network to try and test your devices.
