SYSTEM AND METHOD FOR RFID INDOOR LOCALIZATION
First Claim
1. A system for radio frequency identification (RFID) indoor localization for estimating location of a target object in a localization area, comprising:
- a radio frequency identification (RFID) unit comprising a RFID reader and a plurality of RFID antennas in operative communication with the RFID reader; and
a central unit in operative communication with the RFID unit, the central unit capable of configuring and distributing a plurality of passive reference tags in the localization area;
wherein the central unit is capable ofcollecting data from the passive reference tags through the RFID unit,processing the collected data, andestimating location of the target object, andwherein the central unit employs learning-based location estimation by received signal strength indication (RSSI) and detection rate fingerprinting of passive reference tags and the use of tags with different backscattered range.

Abstract
Disclosed is a system for RFID indoor localization for estimating location of a target object in a localization area, comprising: a radio frequency identification (RFID) unit comprising a RFID reader and a plurality of RFID antennas in operative communication with the RFID reader; and a central unit in operative communication with the RFID unit. The central unit is capable of configuring and distributing a plurality of passive reference tags in the localization area and further capable of: collecting data from the passive reference tags through the RFID unit; processing the collected data; and estimating location of the target object. The central unit employs learning-based location estimation by received signal strength RSSI and detection rate fingerprinting of passive reference tags and the use of tags with different backscattered range.
