Abstract

A system and method for coordinating a plurality of radio frequency identification (RFE)) readers to minimize reader noise and increase reader sensitivity. A first set of one or more of the plurality of readers is coordinated to operate in a transmit only mode. A second set of one or more of the plurality of readers is coordinated to operate in receive only mode. The first and second set are synchronized such that a receive period of the second set coincides with a transmit period of the first set.
