Low-cost, global IoT connectivity now a reality

A CEA-Leti team has designed an ultra-low-power radiofrequency chip that connects fixed or mobile IoT devices to nanosatellites manufactured by the Swiss company Astrocast. Terrestrial IoT networks cover a mere 15% of the planet’s surface, meaning that this new technology is desperately needed in industries such as maritime transportation, fishing, and offshore oil, which operate on the oceans or in other remote areas.

The chip, developed and transferred in just three years thanks to CEA-Leti’s industrial-grade testing facilities, works with Astrocast’s propriety frequencies. It detects satellites in geostationary orbit and corrects the Doppler effect induced by the high speed of these satellites. The module built around the chip is three times cheaper to run than traditional La connectivité IoT bas coût sur 100% du globe, c’est possible
