ELECTRONIC ARTICLE SURVEILLANCE SYSTEM SYNCHRONIZATION USING GLOBAL POSITIONING SATELLITE SIGNAL

摘要

A method and system for synchronizing the operation of a plurality of electronic 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 transmitting the master synchronization signal to the plurality of EAS units. The method and system can further include a secondary synchronization master, which is configurable to relay the master synchronization signal.
