Patent number: 8988199Abstract: A Radio Frequency Identification (RFID) system uses read difficulty factors (RDFs) to improve tag-parameter estimation. During inventory, a reader can obtain a tag's item identifier (II), determine a read metric such as a received signal strength indicator (RSSI), retrieve an RDF associated with the II, and adjust the RSSI using the RDF to more accurately estimate a tag parameter such as distance from the reader antenna. The system can then use the estimated distance to categorize the tag.Type: GrantFiled: September 29, 2011Date of Patent: March 24, 2015Assignee: Impinj, Inc.Inventors: Vincent C. Moretti, Robert C.
