With the supposed manufacturer adherence to RID coming from several drone manufacturers it appears that the RID broadcast from the drone will be in the 5.8GHz WiFi channels and therefore apps can be created that will be able to read the signal. That signal will transmit the location of the controller and the location, altitude, direction of travel, and unique identifier of the drone.
So anyone with the app can track the location of a drone pilot. Only government officials will be able to link the unique identifier with the pilot’s personal information.
