All You Want To Know About SIGFOX IoT Protocol


Sigfox is known for developing wireless networks based on the internet of things that connect various low-energy objects like smart watches, electricity meters, and washing machines. It was founded in 2009 and has emerged into one of the largest IoT service providers in France over the last few years.


SIGFOX enables remote devices to connect with each other with the help of UNB technology and ultra-narrow band. According to Sigfox, “We are the only company that provides global cellular connectivity for the internet of things without being dependent on any existing network.”  A unique thing about Sigfox is that it’s a cellular style system yet works without any help from telecommunication networks.

Why SIGFOX IoT Protocol Is Important

The world will have over 50 billion connected devices by 2020. Most of the nodes will require very low bandwidth to transfer data from one device to another. As the demand for data transfer increases over time, most of these nodes will need systems that are not as complex as traditional cellular networks to keep the cost down and operability intact. That’s where SIGFOX will play a crucial role in IoT deployments across the globe.

Some of the areas where SIGFOX IoT Protocol network can be utilized-

  • Home and consumer goods
  • Healthcare
  • Transportation (automotive management)
  • Energy-related communications (smart metering)
  • Remote monitoring
  • Security
  • Retail (shelf updating, point of sale, etc.)

SIGFOX IoT protocol network is capable of connecting a variety of users and applications. It can be characterized by following-

  • Maximum payload size for each message is not more than 12 bytes
  • Maximum of 140 messages for each object on any given day
  • The range of 3-10km (urban environments) and 30-50km (rural environments).
  • 900 MHz Frequency
  • Wireless throughput of up to 100 bits/second.

The SIGFOX radio access network uses UNB technology (can handle data speed of up to 10 to 1,000 bits per second) which makes it easy to use the low transmitter power levels and still maintain an excellent data connection. The SIGFOX radio uses unique but unlicensed ISM radio bands (in Europe – 868MHz band while in the US – 915MHz). In simple words, transmitting data over a narrow spectrum between two connected objects using these bands is completely free without any need to acquire licenses.

Sigfox network is designed in such a way that it can provide a high-capacity network through a simple star-based cell infrastructure without using excessive energy.

As of now, Sigfox network is being rolled out in a host of cities across Europe for testing purposes. Soon it will be deployed in other parts of the world as well.


  1. Very interesting article, describes well Sigfox. By the way, I think that it’s fully covering some countries in Europe (France, Spain…), and I read that they’re now covering 25% of the Australian population and 50% of the New Zealand population. I indeed can use my devkit here in Sydney.
    Seems like the worldwide deployment is getting real.
