AI summary

An unmanned aerial vehicle (UAV) is dispatched to automatically fly to a location of an antenna indicated by GPS coordinates, automatically recognize the antenna at that location using automated image analysis and object detection, and then start capturing still or video imagery of the antenna in response to the recognition of the antenna. The UAV may be automatically activated to start looking for debris, obstructions or other objects affecting line-of-sight signal reception by the antenna in response to arriving at the location of the antenna and/or detection of the antenna. The UAV may automatically transmit (e.g., in real time) the still or video aerial imagery of the antenna to a backend system for analysis to determine whether there exists a specific issue (e.g., snow or other debris on the antenna) affecting wireless communication involving the antenna.
