Abstract: An RFID performance monitoring system may include systems, methods, or computer program products for collecting information related to the performance of an RFID system. One source of performance-related information can be the RFID readers, both during an active (reading) period and an inactive (listening) period. In various embodiments described herein, a performance monitoring system may collect performance-related information from RFID readers during both during their active and inactive periods.

Abstract: Systems, methods, or computer program products may collect information about the performance of individual RFID tags. In particular, signal strength and/or signal sensitivity of individual RFID tags may be measured and the resulting performance information may be stored in a data repository. In the data repository, the performance information for an individual tag may be associated with an identifier that is uniquely associated with the tag. In one exemplary embodiment, the performance information may be used by an on-line system configured to automatically determine the performance margin with which RFID tags are being read in an RFID system, or to automatically tune the RFID system to achieve a desired performance margin.

Abstract: A system for monitoring and tracking performance of an RFID system collects information about parameters that may impact the performance of an RFID system. In various embodiments, the system may collect information from multiple nodes in the system. The system may perform statistical operations on the collected information to determine their impact on system performance. RFID system performance may be monitored at various nodes in the system, including, for example, individual reader units, environmental sensors, and programming stations. All collected information may be analyzed for the purpose of identifying parameters that contribute to reduced reliability of RFID system performance.
