The drone/vehicle carries a PAW, and senses the signals radiated from nearby RF sources not owned by AERPAW. The PAW may also be a radar, capturing the signals reflected from the environment. The drone needs a safety pilot from AERPAW.
Example experiments: Use drones to capture signals from existing 4G/5G base stations at different drone heights, antenna tilts, transmission frequencies, etc., and characterize the coverage. Such data can be used to optimize coverage of commercial base stations for better serving drones.
