Connect Your IoT Sensors and Devices To The Cloud With Sigfox


Guest blog from Frank Sauber

The barriers to global IoT adoption (cost, energy consumption, and global scalability) no longer exist thanks to Sigfox global IoT network. With its global LPWA (Low Power Wide Area) network, it has reinvented connectivity for the IoT.

From the device energy consumption standpoint, the Sigfox radio protocol drastically 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.

Cost reduction is at the core of Sigfox approach for securely connecting sensors and devices to the Cloud. Device makers can benefit from widely available electronic components, low battery utilization (meaning less maintenance), low solution deployment and integration costs.

With Sigfox, no matter the country, you can have a single IoT device running anywhere in the world and subscribe to one contract for a worldwide network.

IoT connectivity service is offered via a public network based on a star network architecture. A device is not attached to a specific base station unlike cellular protocols. The broadcasted message is received by any base station in the range, 3 in average.

Thanks to a 163.3 dB link budget, the network offers a very long range. In addition, UNB modulation, spatial diversity coupled with the time and frequency diversity of the radio frames repetitions lead to a high capacity of the network. UNB is the best choice to operate on the public ISM band whereas UNB intrinsic ruggedness coupled with spatial diversity of the base stations offer great anti-jamming capabilities.

For developers and engineers, Sigfox is one of the easiest types of connectivity to start with. Many services are offered to rapidly create a device and an end-to-end IoT solutions: The BUILD portal is the dedicated portal for all IoT device makers and solution providers where to find any technical resources and file a request for Sigfox Ready certification. The Sigfox network emulator software emulates Sigfox radio network and Cloud main functionalities to speed up development and tests.

Sigfox radio technology key features:

  • Ultra narrow band (each message is 100 Hz wide and transferred at 100 or 600 bps depending on the region).
  • Random access to the radio frequency resource (no sync with network, devices broadcast their message 3 times on 3 pseudo random frequencies)
  • Small messages (UL: 12-bytes payload for a total frame of 26 bytes/ DL: 8 bytes payload).
  • Cooperative reception (a message is received by 3 different base stations in average).
