innovation for industry
One of the main IoT communication protocols, narrowband IoT, could, with a few minor tweaks, be used for satellite links. A recent study by CEA-Leti for CNES, France’s national center for space studies, leveraged simulation techniques to show that it is possible for a constellation of satellites orbiting a few hundred kilometers above the Earth to connect to several million objects with transmission speeds of a few kilobits per second. The downside is that the Doppler effect (a function of the speed at which the satellite is traveling) must be managed.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
