摘要： The present disclosure describes a system, methods and apparatus for determining a direction of motion of an RFID tag. An RFID reader is provided that includes an antenna that is tilted at a tilt angle with respect to a detection path. Response signals from the RFID tag are received at the antenna at different times, and an RSSI sample of each response signal is measured. Based on the RSSI samples, an RSSI/time data point is generated for each of the RSSI samples. Each RSSI/time data point defines a measured RSSI value for a particular RSSI sample versus a time that particular RSSI sample was measured. Based on the plurality of RSSI/time data points, the direction of motion of the RFID tag can be determined.

摘要： The present disclosure describes a system, methods and apparatus for displaying read range of a nomadic Radio Frequency Identification (RFID) reader based on feedback from fixed RFID beacon tags. For instance, the nomadic RFID reader can transmit an interrogation signal within a space that includes a plurality of fixed RFID beacon tags at known locations, and can receive response signals from a group of the fixed RFID beacon tags. Based on known locations of the group of fixed RFID beacon tags, a read range of the RFID reader can be determined. The read range is defined by the group of the fixed RFID beacon tags. The read range of the nomadic RFID reader can then be displayed on a display along with other information about the fixed RFID beacon tags and/or RFID item tags that are within the read range of the nomadic RFID reader.

摘要： Systems and methods for saving power in a distributed RFID system are provided. One RFID reader includes a RFID radio, a data communication radio, and a controller. The controller is configured to compare a current list of RFID tags responding to a current interrogation signal and a previous list of RFID tags responding to a previous interrogation signal to determine if there has been a change in RFID tags responding to the interrogation signals. The controller is also configured to command the data communication radio to transmit a signal to an external computing device if there has been the change in RFID tags, the signal indicative of the change, or not transmit the signal if there has not been a change. An RFID system includes a central computing device, multiple RFID tags, and multiple RFID readers similar to the above RFID reader.
