Abstract
In one or more embodiments, a disclosed method involves transmitting a first transmit signal(s) having a first signal strength and/or a first field of view (FOV), thereby establishing a first radiation region. The method further involves receiving a first receive signal(s) radiated from an EMID tag(s). Also, the method involves transmitting a second transmit signal(s) having a second signal strength and/or a second field of view (FOV), thereby establishing a second radiation region. In addition, the method involves receiving a second receive signal(s) radiated from an EMID tag(s). Additionally, the method involves subtracting the second radiation region from the first radiation region to determine a difference region. Also, the method involves determining which of the EMID tags are located within the difference region 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 within the difference region.
