description Sigfox Overview
Sigfox is a global network utilizing ultra-narrowband technology to connect Internet of Things devices. It provides low-cost connectivity ideal for transmitting small amounts of data from sensors and equipment.
This LPWAN solution is particularly useful for industrial applications, asset tracking, and smart metering where infrequent updates are sufficient. The technology targets businesses and organizations requiring remote monitoring with minimal energy consumption.
help Sigfox FAQ
What is Sigfox used for?
Sigfox is a low-power wide-area network for small Internet of Things messages from devices such as sensors, meters, and trackers. It is designed for tiny, infrequent transmissions rather than video, voice, or general web browsing.
Is Sigfox the same as Wi-Fi or cellular data?
No. Sigfox uses ultra-narrowband radio and a dedicated IoT network model, while Wi-Fi is a local high-speed network and cellular data supports much larger traffic volumes. Sigfox devices typically trade bandwidth for low power use and wide-area reach.
Can a Sigfox sensor send large files?
Sigfox is a poor fit for large files because its design is optimized for short sensor messages and very low energy use. A camera, firmware updater, or device needing frequent two-way data usually needs another technology such as LTE-M, NB-IoT, Wi-Fi, or LoRaWAN.
What happened to the Sigfox company?
The French Sigfox company entered receivership in 2022 and its assets were acquired by UnaMikr, now associated with the UnaMkr brand. The practical question for a device buyer is whether Sigfox coverage and service are available in the target country.
