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, allowing years of battery life
  • Simplicity - No configuration, connection request or signaling - up and running straight out of the box
  • Cost efficiency - 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 - Thanks to its low cost and ease of configuration, Sigfox can be used as a secondary solution to any other type of network, e.g.: Wi-Fi, Bluetooth, GPRS, etc.

Access the Sigfox service

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

Contracting with a local Sigfox Operator grants you access to the following:

  • The Sigfox public network,
  • The Sigfox Cloud, where you can see and manage all your devices on the network,
  • The Sigfox support platform, available 24/7, for easy troubleshooting while developing your product.

For more information, please contact your country's 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 Sigfox 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 (low noise amplifier), 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. They then start listening for all Sigfox messages 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 developed a range of solutions to cover all of our customer's needs:

  • Connectivity as a Service (CaaS): If you are located in a Sigfox-deployed country but your area is not yet covered, you can rent Sigfox base stations. You can host your own access point and extend the Sigfox network in a simple, flexible, and cost-effective way. Please contact your local Sigfox Operator to access these offers. 
  • SDR Dongle: If you are a device maker located in an area where Sigfox is not yet present, you can buy a Sigfox SDR Dongle. It allows you to locally emulate the Sigfox network, to try and test your devices.
