Sigfox turns out the first global leading IoT network to listen to billions of objects broadcasting data that builds wireless networks to connect low power objects such as agriculture, automotive, construction, electronics, healthcare, etc, which need to be continuously on and emitting small amounts of data. Sigfox provides a software-based communications solution, where all the network and computing complexity is managed in the cloud, instead of on the devices.

Sigfox is a French global network operator founded in 2009 based in Labege near Toulouse, France, and has over 375 employees. The aim of Sigfox is to represent “MAKE THINGS COME ALIVE”, is to give a desire to the physical world and allow billions of objects to play an important role in economic and social development. Sigfox deploying a low-bandwidth dedicated network, already present in 45 countries.

Sigfox API

The Sigfox API permits developers to automate device management and implement data integration in their applications, to share messages, to keep up-to-date with things which are going on. To create a link between Sigfox Cloud and server, two-way communication has been established in order to answer all customer requirements such as callbacks methods, and a REST API. Sigfox API supported URI Query String/CRUD as requested format and JSON as the response format.

Statistics of Sigfox Tracker API

Sigfox network is deployed in more than 45 countries and regions including Malaysia, South Korea, and Switzerland.
The network at present serves around 803 million individuals and spreads 3.8M km per square.



Sigfox has just reached a significant milestone: it now has more than 6 million connected objects in its network.
Total revenue of Sigfox is
50 million euros, a rise of more than 56% year over year, as per the company.

How is it to be integrated?

In order to control and manage devices on the Sigfox network, we have to develop a fully-integrated Cloud platform, with that we can easily integrate into our own platform or server. All in all, there are two ways to integrate as in:

  • Callback method

Callback Method:

Callbacks are available through device types, as they will be activated every time any device of this device type sends a message.

To create a callback, we have to open the callback menu in Sigfox Cloud. And to open callback menu following steps are there:

  • Click on “Device Type” tab
  • Select your “Device Type” that you have

The Call back menu will appear.


After setting up the HTTP Callbacks, we will be able to retrieve messages on our application. But,

  • To manage a huge list of devices.
  • To automatically register new devices when customers activate them.
  • To know there is Sigfox coverage at a designated location.
    We have to build a REST API which will allow us to automate every required action.
    To access this API, we need to create an API Access Token. To do so, when logged on Sigfox Cloud, click on your group, and navigate to the “API Access” tab.


Sigfox employs the differential binary phase shift keying (DBPSK) and the Gaussian frequency shift keying (GFSK) that enables communication using the Industrial, Scientific and Medical ISM radio band which uses 868MHz in Europe and 902MHz in the US.

It uses a wide-reaching signal that crosses easily by solid objects, called “Ultra Narrowband” and requires little energy, termed as “Low Power Wide Area Network (LPWAN)”.

The system depends on a one-hop star topology and requires a mobile administrator to convey the created traffic. The signals can also be used to effectively cover a huge area and to achieve underground objects. Sigfox has many partners in the LPWAN industry few of them are “Texas Instruments, Silicon labs and ON semiconductor”.The current standard for Sigfox communication holds up to 140 uplinks messages per day.

Few are the technologies which are used in Sigfox:

1. Ultra narrow band radio modulation

With the help of Ultra Narrow Band Radio Modulation, Sigfox work in the 200 kHz of the freely accessible band to change radio messages over the air. Each message is 100 Hz wide and exchanged at 100 or 600 bits for every second an information rate, depends on the regions. Thus, long ranges can be achieved while being strong against the noise.

2. Light weight protocol for small messages

Sigfox has custom fitted a lightweight protocol to deal with small messages. Less information to send implies less energy consumption, henceforth longer battery life.

3. Small Payload

An uplink message has up to 12 bytes payloads and it takes an average 2s over the air to achieve the base station, which observes the range searching for UNB signals to demodulate. The payload stipend in downlink is 8 bytes.

4. Star network architecture

A device isn’t connected to a particular base station, not at all like cell convention. The communicated message is received by any base station in the range of 3 on average.

5. Design choices and benefits

Sigfox has created its innovation and network to meet the necessities of mass IoT application, long gadget battery life cycle, low gadget cost, low connectivity expense, and high network range.
