Title (EN) WIRELESS ELECTRONIC ARTICLE SURVEILLANCE SYNCHRONIZATION SYSTEM AND METHOD WITH DATA TRANSFER
(FR) SYSTÈME ET PROCÉDÉ DE SYNCHRONISATION DE SURVEILLANCE D'ARTICLE ÉLECTRONIQUE SANS FIL AVEC TRANSFERT DE DONNÉES
Abstract:
(EN) A method and system are provided for synchronizing a plurality of electronic article surveillance ("EAS") units and providing wireless data transfer by the EAS units. The invention generates a master synchronization signal, transmits the master synchronization signal to the plurality of EAS units and applies the master synchronization signal to trigger a synchronization packet reception period. A beginning of a wireless data transfer period is calculated and initiated based on the triggering of the synchronization packet reception period.
(FR) L'invention porte sur un procédé et un système pour synchroniser une pluralité d'unités de surveillance d'article électronique (EAS) et permettre un transfert de données sans fil par les unités EAS. L'invention génère un signal de synchronisation maître, transmet le signal de synchronisation maître à la pluralité d'unités EAS et applique le signal de synchronisation maître pour déclencher une période de réception de paquet de synchronisation. Un début d'une période de transfert de données sans fil est calculé et déclenché sur la base du déclenchement de la période de réception de paquet de synchronisation.
