RFID (Radio Frequency IDentification) is a special type of wireless communication that allows automatic identification of objects without requiring a line-of-sight. It cannot provide the fullest benefits as a standalone technology. Efficient and successful RFID applications must be developed by smoothly incorporating RFID systems into existing infrastructures to improve business processes and data management capabilities. In this paper, a system architecture that achieves the integration of RFID systems with wireless network technologies (e.g., ZigBee, Wi-Fi, WiMAX, cellular networks) is presented. A control unit is designed to identify objects, gather and manage RFID data, and keep the track of RFID tagged objects without any human involvement from long distances.
