In Ubiquitous computing, RFID has been become a key technology to provide the real-time location information of users. For this purpose, many recent researches have been conducted regarding RTLS based on the RFID system. In this study, we evaluated the efficiency and feasibility of the velocity gauging system using RTLS based on the RFID system. By using this system, the velocity of mobile units were measured and the accuracy was evaluated with data obtained from DGPS. The results demonstrated that RTLS based on the RFID system would be suitable to measure with relatively low velocity information of mobile units. When RFID infrastructures are being constructed, the developed system will be a better position to increase popularity of velocity information service.
