Abstract: A robust system, apparatus, and method for precise in-house positioning utilizing RFID (Radio Frequency Identification) technology are described in this invention. The in-house environment is partitioned into separate locations, and a set of RFID tags are scattered in the environment. Reading patterns of RFID tags are collected at each location by an RFID reader as samples. Pattern recognition and classification methods are used, when human, vehicle, or other carrier move around the environment with an RFID reader to estimate its physical location based on the reading pattern. The precision can be within one meter. The method is adaptive to different tag distribution, reader range, defective tags, and other physical constraints.
