Summary:Systems (100) and methods (900) for detecting the presence of a security tag. The methods involve performing operations by a master pedestal of an EAS system to determine a first Tx/Rx scheme to be used during a first iteration of an EAS tag detection process based on (A) a first total number of time windows randomly selected from a plurality of total number of time windows in which an EAS exciter signal should be transmitted from at least one pedestal, and (B) first time windows randomly selected from a plurality of time windows in which the EAS exciter signal can be sent during the EAS tag detection process. Information specifying the first Tx/Rx scheme is communicated from the master pedestal to at least one slave pedestal. Transmit and receive operations are performed by the master and slave pedestals in accordance with the first Tx/Rx scheme.
