  • Radio frequency identification readers, methods and computer program products for adjusting a query command slot-counter parameter Q
    Patent number: 9754143
    Abstract: RFID readers and methods for adjusting a query command slot-count parameter Q for use by radio frequency identification (RFID) tag reader in an RFID tag inventory round are provided. A method for adjusting a query command slot-count parameter Q for use by an RFID tag reader includes setting an initial value for Q for a first inventory round, issuing a query command to a population of RFID tags, and monitoring replies from the population of RFID tags. The value of Q is decreased by a first amount if no reply is received, and the value of Q is increased by a second amount different from the first amount if a tag collision reply is received.
