Abstract
A system and method for precisely locating a mobile device at a precise geographical distance and messaging to communication devices carried by persons in specific areas is disclosed. The method utilizes at least two elements, a mobile device and at least one location tag. When activated, the mobile device will interact with all of the location tags in range and determine the location tag most practically near. The mobile device will then download detailed local information from the location tag most practically near. The messaging system may be used to selectively send messages to communication devices known to be within range of location transmitters or tags in a predetermined area.
