Drone detection in cities is expensive. Dedicated radar installations are cost-prohibitive at scale, cameras have limited range and stop working well at night, and LiDAR systems have the same cost problem as radar. A group of researchers at the University of Science and Technology of China spent the past year working on a different approach: using 5G-Advanced base stations that are already in the ground to do the job instead. The 5G-A base station Active … More → The post Tracking drones with the 5G tower down the street appeared first on Help Net Security .
