ABSTRACT:
A tag receives a wireless signpost signal that contains a signpost code, converts the signpost code into location information representative of a physical location of a signpost that transmitted the received signpost signal, and transmits a wireless tag signal that includes the location information. In a different configuration, a tag receives a wireless signpost signal that includes a signpost code, and determines whether the signpost that generated the received signpost signal is a replacement for a different signpost. If it is a replacement, the tag transmits a wireless tag signal containing an information portion that relates to the signpost replaced by the signpost that generated the received signpost signal.
