Abstract

A multiuse system for use with Wireless Display Tags (WDTs) includes, in one or more exemplary arrangements, techniques for automatically maintaining synchronicity between pricing data for a product and advertising, marketing or promotional data associated with that product, and for detecting the proximity and location of a customer within a category of goods displayed within a managed environment. A messaging format suitable for such low power operation among a large number of peers is also disclosed, as is a technique for integrating a plurality of smaller displays to yield a single large display. An access point capable of serving as a communications hub within such a network, while at the same time offering visual and audio surveillance capabilities, is also disclosed.
