ABSTRACT:
A message delivery system (12) automatically delivers messages (44) through mobile units (20) as the mobile units (20) travel within a predetermined area (10). Each message (44) is delivered only when the mobile unit (20) is near a point of interest (16) which is the subject of the message's content. Each message (44) is delivered in its entirety, from beginning to end, without repetition. Que points (24) are defined to reside before corresponding points of interest (16) when mobile units (20) travel in particular directions. Based upon these particular directions of travel, message content may be configured to describe points of interest (16) using left or right relative directional references. Messages (44) are delivered in real time, and their content may change quickly and frequently. A control station (18) controls the programming of the mobile units (20) and sends programming communications (48) over the air to change mobile unit programming as needed.
