Design and implementation of an active RFID system platform

An active RFID system has the active tag that incorporates an internal battery providing a robust, long-range transmission signal. Typical application using the active RFID is the identification and the position tracking of warehouse inventory-item and freight container. This paper presents the design and implementation of an active RFID system platform which complies with the ISO/TEC 18000-7 standard. Our system design focus on three parts: 1) the standard compliance with the ISO/TEC 18000-7, 2) the energy saving mechanism to maintain the longevity of tags as long as possible, and 3) the high identification rate in the presence of multiple tags. We describe the detailed design of the system and the commercial off-the-shelf (COTS) implementation. The performance evaluation of the system is also included.
