Abstract
Systems and methods for selectively limiting read zones are disclosed herein. An example method includes synchronizing signal transmissions from a first antenna associated with a first reader and a second antenna associated with a second reader to generate (i) a first read zone corresponding to the first antenna, (ii) a second read zone corresponding to the second antenna, and (iii) a null zone between the first read zone and the second read zone that prevents the first reader and the second reader from reading tags located in the null zone. The example method further includes linking (i) the first reader with a tag located in the first read zone or (ii) the second reader with a tag located in the second read zone based on an energy ratio of a first signal transmitted by the first antenna to a second signal transmitted by the second antenna.
