Performance Evaluation of Real-Time Indoor Positioning with Active-RFID and CSS-Based Nano Lock System

Various indoor positioning methods have been proposed both in theory and practice. Each method has different degree of accuracy. Due to the smaller indoor venues, the torrent for error is also smaller. Therefore, indoor positioning system requires more precise measurement than outdoor. We use active RFID and real-time nano-precision positioning devices to assess the feasibility of indoor positioning system. This study is to conduct experimental study of the distance measure using RSSI and TDOA, and analysis the experimental results.
