What is Sigfox? Features of Sigfox in IoT Applications
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 cellular like system which connects remote devices using Ultra Narrow Band(UNB) technology. It is mainly targetted for low data rate applications. It requires substantially less antennas compare to traditional cellular networks such as GSM/CDMA.
SIGFOX is the name of operator which has developed first cellular network which provides low throughput wireless communication. With its UNB patented technology, they have made revolution in the era of M2M and IoT. The network based on this technology already have connected thousands of devices in country such as France and also in international cities.

SIGFOX wireless technology basics in M2M and IoT
Following are the key features/specifications of SIGFOX technology.
| Specification/feature | SIGFOX Support |
|---|---|
| Frequency | Unlicensed ISM Band 868 MHz(Europe) 915 MHz(USA) |
| Range | 30 to 50 Km (Rural areas) 3 to 10 Km (Urban areas) |
| Throughput | 100 bps |
| Payload size to be transmitted | Very less(about 12 bytes) |
| Power consumption | Very less, for example, energy meter in SIGFOX will consume 50 microwatts while in GSM cellular system it consumes 5000 microwatts |
| Stand by time for 2.5Ah battery | It takes 20 years in SIGFOX, while GSM cellular takes very less about 0 to 2 years |
| uplink/downlink | supports mono as well as bi-directional communication |
| Frequency Hopping | Supported |
| Security/Privacy | SIGFOX employs various techniques to support this |
Conclusion
Sigfox revolutionizes IoT communication with its simplicity, efficiency and scalability. Its focus on low power and long range connectivity enables IoT devices to operate effectively in diverse industries, from smart cities to industrial IoT.
