The National Frequency Agency (ANFR) manages all radio frequencies in France. This rare and strategic resource, used for all wireless communications, belongs to the public domain of the State which entrusted its management to ANFR. As such, its mission is to negotiate, at the international level, the future uses of the frequency bands and defend French positions. It also authorizes all implantations of emission sites (> 5 watts) on the territory and ensures compliance with the limits of public exposure to the airwaves. Finally, it controls the use of frequencies and ensures a good coexistence of their uses by all users.
