Abstract

An example disclosed method includes defining a first zone within a monitored area, a first group of receivers covering the first zone; defining a second zone within the monitored area, a second group of receivers covering the second zone; determining, via a processor, a first position of a first tag based on timing measurements obtained via the first group of receivers; determining, via the processor, whether the first position indicates that the first tag is within the first zone; and when the first position indicates that the first tag is not within the first zone, not reporting data associated with the first tag.
