dc.description.abstract This thesis addresses this problem of a precise RTLS (Real Time Location System) by implementing a Passive UHF RFID system. A software is created that connects to an RFID reader and accesses it's functionality to collect the tag's backscatter power which is the RSSI (Received Signal Strength Indicator), and the tag's ID. The software also connects with a web camera, and locates the tags within the camera's point of view by using only the RSSI of the tag. This software is capable of computing the locations of tags by locking on each tag's unique EPC, and marking their location and corresponding tag ID on the screen. By seeing the tag on the screen, and marker which indicates the calculated location, we can get an idea of the accuracy of this system. The calculations involve the simplified path loss model which computes the tag's distance from the reader antennas, followed by multilateration calculation which locates the tag on a two dimensional plane in front of the web camera. Because of the environmental factors, the software first runs a calibration process to map the environment using numerous calibration tags with known locations prior to locating tags with unknown locations. The result of this work is a tool which can be used to identify, locate and track tags in real time, and also to analyze the environment and the RFID localization in general. en_US
