A method for enhancing the accuracy a Radio Frequency IDentification
(RFID) system which may exhibit inconsistent RFID tag reporting behavior.
The method includes the steps of (i) establishing a timeout setting
indicative of the time that each interrogating antenna transmits RF
energy within a respective read field, (ii) evaluating/comparing
reporting results over multiple interrogation cycles to determine when an
RFID tag exhibits inconsistent reporting behavior within the read field
and (iii) increasing the timeout setting of the respective interrogating
antenna to enhance the energy harvested by an RFID tag/device during each
interrogation cycle. In lieu of, or in addition to, increasing the
timeout setting, the method evaluates the responses received over
multiple cycles and accepts such responses as being valid only when the
same response is obtain over consecutive/sequential interrogation cycles.
That is, the system evaluates the results of several cycles before
accepting the validity or veracity of the response.
