WIRELESS CONNECTIVITY FOR SENSORS

摘要

A wireless access point communicates messages in an electronic article surveillance (EAS) network. The EAS network includes at least one EAS sensor hard-wired to at least one wireless device node. The wireless access point includes a wired communication interface, a wireless communication interface and a controller. The controller is electrically coupled to the wired communication interface and to the wireless communication interface. The wired communication interface operates to receive a message. The message includes a sub-layer address corresponding to an EAS sensor. The wireless communication interface operates to broadcast the message and to receive an acknowledgement of the broadcast message. The acknowledgment originates from the EAS sensor corresponding to the sub-layer address. The controller operates to transfer the message between the wired communication interface and the wireless communication interface.
