Abstract
A messaging system is disclosed, delivery of messages being dependent upon the location of the recipient, the number of recipients being unlimited. The message transmitter may be fixed or mobile. The recipient may be either fixed or mobile, but must have knowledge of its own position. The transmitter broadcasts in radio frequencies (or other convenient medium) three pieces of information per message: a location, a trigger distance, and the message. The recipient, knowing its own position, calculates the actual distance to each location being broadcast. If the actual distance is less than the trigger distance, then the message is displayed to the recipient. In this manner, only messages that are relevant to the recipients' position are displayed, and messages relevant to other positions are ignored.
