Sigfox

Definition

Sigfox is a low-power wide-area network (LPWAN) technology specifically designed for the Internet of Things (IoT) that allows devices to communicate over long distances with minimal energy consumption. It provides a cost-effective solution for connecting numerous IoT devices in various applications such as smart cities, agriculture, and industrial monitoring, enabling them to send small amounts of data efficiently.

5 Must Know Facts For Your Next Test

1. Sigfox operates on unlicensed radio frequency bands, which helps reduce operational costs and allows for the deployment of large networks without heavy regulatory restrictions.
2. The technology is optimized for sending small packets of data (up to 12 bytes per message), making it ideal for applications that require infrequent updates rather than continuous data streams.
3. With a range of up to 50 kilometers in rural areas and 10 kilometers in urban environments, Sigfox provides extensive coverage for connected devices.
4. Sigfox's network architecture is designed to support millions of devices within a single network, allowing businesses to scale their IoT solutions easily.
5. The energy efficiency of Sigfox enables battery-operated devices to last several years, reducing maintenance costs and the need for frequent battery replacements.
