An RFID system includes a central RF network controller and a failover antenna within a read point zone that spans multiple antennas and RFID readers. The system includes a first RFID antenna configured to read RF tag data within a first read point, a second RFID antenna configured to read the RF tag data within a second read point, and a failover RFID antenna. A controller communicatively coupled to the failover RFID antenna, the first RFID antenna, and the second RFID antenna is configured to group the first, second, and failover RFID antennas in a read point zone and to receive RF tag data from the first, second, and failover RFID antennas and assign the tag data to the read point zone. The controller is further configured to receive a failure notification associated with failure of one of the first and second RFID antennas and activate the failover RFID antenna upon receipt of the failure notification.
