Abstract
A locating system and method employs a plurality of radio frequency readers arrayed with respect to a region having a plurality of zones within which a plurality of radio frequency tags are to be located. Each reader identifies those tags present within its coverage area. The coverage areas of all the readers taken together substantially cover the region and at least part of the coverage area of each reader overlaps at least part of the coverage area of at least one other reader. A data processor receives the identification of the tags within the coverage area of each reader and applies a set of locating rules to determine therefrom in which zone within the region each identified tag is located.
