Behind the scenes, Brazilian authorities have taken bold new steps to keep drones away from designated Olympic areas, but not all of the new measures are effective. The country has partnered with drone manufacturers like DJI to update the onboard software with Olympic geofences, preventing drones from flying in the forbidden areas. But not every manufacturer has taken up the self-imposed limits, so to stop other drones, the Brazilian military has purchased new devices to jam drone-control signals in mid-flight. These jamming devices required the telecom regulators to grant the military new legal authorities over the civilian airwaves. It’s an aggressive step, and one that many observers worry could lay the groundwork for cell-service blackouts after the games have finished.
