ELECTRONIC ARTICLE SURVEILLANCE SYSTEM SYNCHRONIZATION USINGGLOBAL POSITIONING SATELLITE SIGNAL

摘要

A method and system for synchronizing the operation of a plurality of ele ctronic article surveillance ("EAS") units that includes receiving a global positioning satellite reference signal, generating a synchronization master signal using the global positioning satellite reference signal and transmitt ing the master synchronization signal to the plurality of EAS units. The met hod and system can further include a secondary synchronization master, which is configurable to relay the master synchronization signal.
