Information about the real-time location of an object (e.g., a football) within a venue (e.g., a sport stadium), as determined by an object tracking system, may be used to generate communications that are then transmitted via wireless transmitters to one or more user devices (e.g., smartphones of venue spectators) located within the venue. The communications may be triggered by particular event triggers (e.g., the football enters a goal area, the football travels a particular distance, the football reaches a particular velocity, the football reaches a particular height), and the communication may be based on the event trigger that was reached. The wireless transmitter may be a local wireless transmitter, so that only user devices within the venue receive the communication.
