Abstract

This paper investigates an indoor location estimation system based on UHF band RFID. Tags, separated by 50 cm, are attached to the ceiling and an RFID reader is attached to the person of interest. The location of the person is estimated using the tags´ coordinate which are read by the RFID reader. Three simple location estimation algorithms are proposed, and their estimation accuracy is evaluated by an experiment. This paper also presents a ray trace simulation; tag allocation, RFID reader parameters, and location estimation algorithms are evaluated by simulation to minimize the estimation error.
