MEDIA ACCESS CONTROL (MAC) FOR AN ACTIVE RFID SYSTEM

摘要

A system of radio frequency communication between Readers and Tags where each tag is given a unique tag ID. The Tags are configured to send and receive radio communication to and from the tag Reader and the Media Access Control protocol is configured to control the radio communication between the tag Reader and the plurality of Tags. The Media Access Control protocol includes a multidimensional addressing scheme allowing Readers to efficiently address tag communities ranging from small to very large in unicast, multicast and broadcast modes.
