在本文中，我们确定了无源UHF RFID标签和阅读器的技术能力的状态，使用一个简单的，经验的，实验的方法。本文并不关注RFID系统在理想环境中的理论能力，而是对市售ISO 18000-6c系统的状态进行务实的评估，并确定技术改进的机会。我们研究的自由空间读取距离的标签的读者，近金属读取距离，近水读取距离，在这些环境中的读取距离的频率依赖性，在这些环境中的近场读取距离，读取速度，并确定正向或反向通道的限制。
In this paper, we identify the state of the technical capability of passive UHF RFID tags and readers using a simple, empirical, experimental approach. This paper does not focus on theoretical capabilities of RFID systems in ideal environments, but rather a pragmatic evaluation of the state of commercially available ISO 18000-6c systems and identifying areas where there are opportunities for improvements in the technology. We examine the free-space read distance of tags by readers, near-metal read distance, near-water read distance, frequency-dependence of read distance in those environments, near-field read distance in those environments, read speeds, and a determination of forward or reverse channel limits.
