Abstract
Radio Frequency Identification (RFID) technology having been realized of its potential usages only in recent years and nowadays it is widely used in multidisciplinary industries and applications. Indoor positioning systems (IPSs) locate objects in closed structures such as office buildings, hospitals, stores, factories, and warehouses, where Global Positioning System devices generally do not work. This paper introduces a unidimensional IPS using the RFID technology using the Received Signal Strength Indication (RSSI) to estimate the position of a reduced scale mobile vehicle and compare with the distance measured by an ultrasonic sensor. Results show a root mean square error of 5.7 cm.
