Sigfox: Features and Applications in IoT

Introduction

Sigfox is a low power wide area network (LPWAN) technology specifically tailored for IoT applications. It offers a robust communication platform for devices needing long range connectivity and minimal power usage. This guide highlights Sigfox’s key features, such as low bandwidth, scalability and cost efficiency, which make it a preferred choice for IoT solutions.

SIGFOX is a cellular-like system which connects remote devices using Ultra Narrow Band (UNB) technology. It is mainly targeted for low data rate applications. It requires substantially fewer antennas compared to traditional cellular networks such as GSM/CDMA.

SIGFOX is also the name of the operator which developed the first cellular network providing low throughput wireless communication. With its UNB patented technology, they have revolutionized the era of M2M and IoT. The network based on this technology has already connected thousands of devices in countries such as France, and in international cities.
