In one or more embodiments, a disclosed method involves transmitting a firsttransmit signal(s) having a first signal strength and/or a first field of view(FOV),thereby establishing a first radiation region. The method further involvesreceiving afirst receive signal(s) radiated from an EMID tag(s). Also, the methodinvolvestransmitting a second transmit signal(s) having a second signal strengthand/or asecond field of view (FOV), thereby establishing a second radiation region. Inaddition, the method involves receiving a second receive signal(s) radiatedfrom anEMID tag(s). Additionally, the method involves subtracting the secondradiationregion from the first radiation region to determine a difference region. Also,themethod involves determining which of the EMID tags are located within thedifferenceregion by using the first receive signal(s) and the second receive signal(s).Further,the method involves determining a location of the EMID tag(s) located withinthedifference region.
