Drones can be as disruptive as they are beneficial. Dedrone’s City-Wide Drone Detection product throws a virtual shield around a geographical area, warning law enforcement within seconds if a drone has entered the designated airspace. Dedrone tracks a proprietary blend of signals from drones, including radio frequency, ADS-B data (also used in planes), and RemoteID beacons, to identify the location of incursions. Mary-Lou Smulders, the company’s chief marketing officer, compares it to an air traffic control system for drones—something that didn’t previously exist. Customers include Con Edison, which is using it to protect its infrastructure; Barcelona’s police force; and an unspecified number of airports.
