Abstract
A system for communicating between a store computer and locations in the les of a retail facility. A hard wired grid connects the store computer to a plurality of transceivers located in zones throughout the facility and the transceivers establish a wireless link to the locations. One embodiment is a product information display system in which the locations are fixed information display terminals, such as price displaying shelf tags. Another embodiment is an item tracking system, in which the locations are movable shopping carts or baskets.
