Study on inconsistency of RFID tag recognition distance

With the rapid development of internet and other information industry, the applications of RFID become more extensive and in-depth. A great many applications call for a limitative tag recognition distance, and the tag producing and testing are strictly demanded. Presently, we are difficult to control the tag recognition distance during the production, and it is a bottleneck problem for RFID technology and products. In RFID system, the inconsistency of tag recognition distance affects many applications terribly. To solve this problem plays a significant role in not only existing application systems but also the future ones. In this paper, by discussing the causation for the inconsistency effect, a novel expiation scheme based on data analyzing and processing is proposed, and it is feasible and effective.
