Claim:
1. A method for detecting the presence of a security tag, comprising: performing operations by a master pedestal of an Electronic Article Surveillance (“EAS”) system to determine a first Tx/Rx scheme to be used during a first iteration of an EAS tag detection process based on communicating information specifying the first Tx/Rx scheme from the master pedestal to at least one slave pedestal of the EAS system; performing transmit and receive operations by the master and slave pedestals in accordance with the first Tx/Rx scheme; and transmitting the EAS exciter signal from the at least one pedestal a first number of times during a second iteration of the EAS tag detection process, where the first number of times is different than a second number of times the EAS exciter signal was transmitted from the at least one pedestal during the first iteration of the EAS tag detection process; wherein the first Tx/Rx scheme specifies during which time windows of the plurality of time windows a pedestal is to only transmit, only receive, or both transmit and receive.
