Arrangement for, and method of, optimizing radio frequency (RF) identification (RFID) reading performance
First Claim
1. An arrangement for optimizing radio frequency (RF) identification (RFID) reading performance when reading RFID tags associated with products in a venue, the arrangement comprising:
- a sensing system including a plurality of stationary RFID readers deployed overhead in the venue, and operative for reading the RFID tags over a plurality of RF reading zones in the venue in a stationary reading mode of operation;
at least one mobile RFID reader operated by a user in the venue, and operative for reading the RFID tags in at least one of the reading zones in a mobile reading mode of operation;
a locationing system for locating the at least one mobile RFID reader in the at least one reading zone in the venue; and
a host server operatively connected to the stationary and mobile RFID readers and to the locationing system, and operative for synchronizing the operation of the stationary RFID readers with the operation of the at least one located mobile RFID reader, for determining when the at least one located mobile RFID reader is in substantially simultaneous, synchronous operation with the stationary RFID readers, and for modifying at least one of the modes of operation in response to the determination of the substantially simultaneous, synchronous operation to optimize the reading performance by the stationary and mobile RFID readers.

Abstract
Multiple stationary radio frequency (RF) identification (RFID) readers are deployed overhead in a venue and are operated to read RFID tags. A mobile RFID reader is also operated in the venue for reading the RFID tags. The mobile reader is located in the venue, and a host server synchronizes the operation of the stationary readers with the operation of the mobile reader, determines when the mobile reader is in substantially simultaneous, synchronous operation with the stationary readers, and responsively modifies the operation of the stationary and mobile RFID readers to optimize the RFID reading performance.
