Design and implementation of a long-range RFID reader

Abstract

This article introduces the theory of Radio Frequency Identification (RFID) system, and gives a design scheme of long-range RFID reader based on ISO18000-6B protocol. The coding and decoding of the signals in the communication links, and its anti-collision are discussed. The design of the hardware and software and the implementation are proposed. Test result shows the reader is stable, reliable and easily configurable.
