Abstract: 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.

Abstract: The present disclosure describes a system, methods and apparatus for determining location of an item within a space. Each particular item is associated with a particular Radio Frequency Identification (RFID) item tag that uniquely identifies the particular item. A plurality of fixed Radio Frequency Identification (RFID) readers are provided in the space, and each of the fixed RFID readers is fixed at a particular known location within the space. Each of the fixed RFID readers can transmit an interrogation signal. Upon receiving a first interrogation signal from one of the fixed RFID readers, a first RFID item tag transmits a response signal. The first fixed RFID reader receives the response signal transmitted by the first RFID item tag, and can therefore determine that the first RFID item tag is located within a read range of the first fixed RFID reader.
