    • The present invention relates to a method of estimating an indoor position based on a wireless LAN. The method includes the steps of: receiving a received signal strength (RSS) value of a received signal of a common AP, which is measured by a private AP, RSS values of the common AP and the private AP, which are measured by a terminal; estimating position information on the private AP using the RSS value of the common AP, which is measured by the private AP; and calculating a first position estimation error of the terminal using the RSS value of the common AP according to a fingerprint scheme, calculating a second position estimation error of the terminal using the position information of the private AP and the RSS value of the private AP according to a propagation attenuation model, and determining a final position of the terminal using the calculated first and second position estimation errors.
    • 本发明涉及一种基于无线LAN估计室内位置的方法。 该方法包括以下步骤:接收由专用AP测量的公共AP的接收信号的接收信号强度(RSS)值,由终端测量的公共AP和专用AP的RSS值 ; 使用由私有AP测量的公共AP的RSS值来估计私人AP上的位置信息; 以及根据指纹方案使用公共AP的RSS值计算终端的第一位置估计误差,使用专用AP的位置信息和专用AP的RSS值来计算终端的第二位置估计误差, 传播衰减模型,以及使用所计算的第一和第二位置估计误差来确定终端的最终位置。
