Ti based on the RFID chip RI

主要介绍RFID标准，有需要的朋友可下来-RFID standard

利用 RSSI值对几何估算区域进行划分，运用改进公式计算出新的未知节点位置。(The geometric estimation area is divided by RSSI value, and the new unknown node position is calculated by the improved formula)

RFID communicate. This is for reading rfid card.

无线通信方面的，读IC卡卡号，并以无线的方式传送出去-wireless communications, Reading IC card card number, and the wireless transmission away

在分析射频识别"Wc+/#基本原理和特点基础上!重点讨论了基于Wc+/ 的Y.WF/b.W-室内定位系统!然后在此基础上提出了一种最近邻居改进算法和基于误差多级处理的数据融合定位方法$仿真结果表明!改进后的最近邻居算法比已有的最近邻居算法的定位精度更好(In the analysis of radio frequency identification "Wc+ /# based on the basic principles and features! focused on Wc+ / s Y.WF/bW- indoor positioning system! then puts forward an improved algorithm and the nearest neighbor multi-level error Positioning method of data fusion processing simulation results show that the $! improved nearest neighbor method nearest neighbor algorithm than the existing positioning accuracy of better)
