With a global network able to listen to billions of devices broadcasting data, Sigfox is the world's leading provider of connectivity for the Internet of Things (IoT). Sigfox can pick-up very small signals sent by IoT devices from around the world – using the lowest amount of energy to the point where natural energy harvesting technology will be enough to power data transmissions.
A powerful solution based on 3 pillars:
- Low energy consumption: our unique connectivity solution provides the lowest energy-consumption device-to-cloud. By simplifying communications, we enable unbeatable low energy consumption. Soon, there'll be no need for replacing or re-charging batteries since the devices will generate energy themselves.
- Low cost: with its simple approach to connectivity, Sigfox provides extremely price-competitive connectivity subscriptions and even more importantly, enables extremely simple and cost-efficient silicon modules.
- Complementary technology: Sigfox is compatible with Bluetooth, GPS 2G/3G/4G and Wi-Fi. By combining other connectivity solutions with Sigfox, business cases and user experience can be drastically improved.
Sigfox, it's about connecting the unconnected! An inexpensive, long distance and lower power solution that's primed for multiple industrial and consumer applications. Through its global LPWA network and rich ecosystem of expert partners, Sigfox delivers out-of-the box, two-way, secured communication services to unlock the true potential of the Internet of Things (IoT). Sigfox provides a standard way of collecting data from sensors and devices with a single, standard-based set of APIs. Moreover, the Sigfox disruptive technology complements traditional cellular M2M by enabling global, ubiquitous, ultra-long battery life solutions at the lowest cost.
ST offers a complete Sigfox ecosystem built around our high-performance ultra-low-power S2-LP RF transceiver, and long-range wireless STM32WL microcontrollers. Designers can quickly get started with our Sigfox USB Kickstart Development Kit as well as benefit from an extensive set of evaluation boards, software, firmware and application notes to help reduce development time and costs.
