DISPLAYING RADIO FREQUENCY IDENTIFICATION (RFID) READ RANGE OF AN RFID READER BASED ON FEEDBACK FROM FIXED RFID BEACON TAGS
First Claim
1. A method, comprising:
- transmitting an interrogation signal from a nomadic Radio Frequency Identification (RFID) reader over an actual coverage area within a space, wherein the space includes a plurality of fixed RFID beacon tags at known locations;
receiving, at the nomadic RFID reader, response signals from one or more fixed RFID beacon tags in the actual coverage area;
determining, based on the response signals and the known locations of the one or more fixed RFID beacon tags, an approximate coverage area of the interrogation signal; and
displaying the approximate coverage area of the nomadic RFID reader on a display, wherein the approximate coverage area displayed on the display is defined by the one or more fixed RFID beacon tags that responded to the interrogation signal.

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.
