Sigfox the world’s leading IoT Provider

Sigfox is the world’s leading provider of connectivity for the Internet of Things (IoT). The company has built a global network to connect billions of devices to the Internet while consuming as little energy as possible, as simply as possible.

 

Key Features

 
 
 
Sigfox-Icon-03

Low energy

The Sigfox radio protocol reduces the radio frame size and no synchronization with the network is required. Combining a low power emission level and short emission enables maximum autonomy of objects.
Sigfox-Icon-04

Low cost

Benefit from widely available electronic components, low battery utilization, low solution deployment and integration costs, as well as our simple network infrastructure with long range high capacities.
Sigfox-Icon-05

Complementary

Sigfox is complementary to Bluetooth, GSM 2G/3G/4G and Wifi. By combining other connectivity solutions with Sigfox, business cases and user exprience are drastically improved.
Sigfox-Icon-06

Simple

Removing the need to configure connections and enabling standard based device to cloud integration, means that Sigfox is easier to use for everyone.
Sigfox-Icon-07

Global

Connecting globally is easier than ever. Partners subscribe to one contract for a worldwide network. And since our network functions in the same way globally, no matter the country, you can have a single device running anywhere in the world.
 

Radio technology

Ultra narrow band

Sigfox uses 200 kHz of the publicly available and unlicensed bands to exchange radio messages over the air (868 to 869 MhZ and 902 to 928 MHz depending on regions). Sigfox uses Ultra Narrow Band (UNB) technology combined with DBPSK and GFSK modulation. Each message is 100 Hz wide and transferred at 100 or 600 bits per second data rate depending on the region.

Random access to the radio frequency resource

The transmission is unsynchronized between the devices and the network. They broadcast each message 3 times on 3 different frequencies (frequency hopping). The base stations monitor the spectrum and look for UNB signals to demodulate.

Small messages

Sigfox has tailored a lightweight protocol to handle small messages. An uplink message has a maximum 12-bytes payload and a downlink of 8 bytes. For a 12 bytes data payload, a Sigfox frame will use 26 bytes in total.
