ABSTRACT:
This invention relates to a system and method for locating mobile objects. The system includes many signposts positioned within a monitored area and many mobile objects. The monitored area is subdivided into subareas. Many signposts are positioned in each subarea. Each signpost transmits a vote signal having encoded therein a subarea code identifying the subarea that the signpost is positioned in. The mobile objects receive the vote signals and detect the subarea codes encoded therein. The location of a mobile object is determined to be one of these subareas having a maximum count of signposts that are positioned in that subarea and that are in range of the mobile object.
