Backscatter radio wireless communication by modulating signals scattered from a radio frequency transponder (RF tag) is fundamentally different from conventional radio because it involves two distinct links: the power-up (forward) link for powering the passive RF tags, and the backscatter (return) link for the describing backscatter communication. Because of severe power limitations on the RF tag such as chip sensitivity, antenna gain, antenna polarization and impedance match, a thorough knowledge of the backscatter channel is necessary to maximize backscatter-radio and radio-frequency identification (RFID) system performance. This paper examines the relative roles of the forward and reverse links in determining power received in tag, return power in reader, power ratio and the operational range of passive UHF RFID systems. It analysed the limitations imposed on the range performance of passive UHF RFID systems by such factors as tag characteristics, propagation environment, and RFID reader parameters.
