A conceptual study of long range active RFID system for reliable data communication

Radio Frequency Identification (RFID) system has shown remarkable progress, especially in identifying, locating, or tracking objects. Some of the existing challenges include improving position estimation beyond RFID coverage. Following a brief introduction, an analysis of the new requirements of the indoor location system-based RFID and a system prototype is presented. To this end, this research proposed a combination of ZigBee-based RFID; the system consists of multi-hop tags that can communicate with many wireless devices not limited to readers and long-range reader based on an active RFID technology integration with wireless transceivers in a self-healing mesh network using the IEEE 802.15.4-protocol. The system design focuses on many aspects such as: standard compliance with the IEEE 802.15.4 protocol, recognition of multiple tags faster than the collision resolution, and achievement of a long communication range to communicate with tags.
