    • The present invention relates to a method of automatically generating a fingerprint database for indoor wireless location. For this purpose, the present invention provides a method of generating a fingerprint database that determines a method of calculating the strength of signals transmitted from a plurality of access points, calculates the strength of signals at nodes of a plurality of vertical and horizontal grids set in an indoor space, and generates a database table by using the location information about the nodes and the calculated strength of the signals. Further, the present invention provides an environment analysis tool including a communication module that performs communication between at least one of the access points and a receiving terminal, an environment analysis module that calculates the strength of a signal at a specific location by using a method of calculating strength and generates a fingerprint database table, and a fingerprint database that stores the fingerprint database table. According to the present invention, it is possible to reduce time and manpower required to build a fingerprint database, and to easily build a new fingerprint database even though an indoor structure is changed.

    • The present invention relates to a location measuring method using an access point, and an apparatus using the same. According to the present invention, a location of a terminal is estimated by using a signal strength received from an access point installed at a known position in a wireless network, and location of the access point installed at an unknown position is estimated by using a signal strength received from the access point installed in the unknown position and estimated location information of the terminal. In addition, a location of the terminal is finally calculated by using estimated location information of the access point installed at the known position. As described, the location of the terminal is determined by using estimated location information of an AP that is randomly installed by a user (that is, installed at an unknown position), and therefore a location of an AP installed in an area where it is difficult to measure and availability of location measurement can be improved. In addition, a signal strength measurement value, estimation location information of an AP installed at a known position, and estimation location information of an AP installed at an unknown position are used for location information calculation of a terminal, and accordingly, accuracy of the location measure can be improved.
    • 本发明涉及使用接入点的位置测量方法及其使用方法。 根据本发明,通过使用从安装在无线网络中的已知位置的接入点接收的信号强度来估计终端的位置,并且通过使用信号来估计安装在未知位置的接入点的位置 强度从接入点接收到的安装在未知位置和终端的估计位置信息。 此外,终端的位置最终通过使用安装在已知位置的接入点的估计位置信息来计算。 如上所述,通过使用由用户随机安装的AP(即,安装在未知位置)的AP的估计位置信息来确定终端的位置,并且因此安装在其所在区域中的AP的位置 难以测量和可用性的位置测量可以提高。 此外,信号强度测量值,安装在已知位置的AP的估计位置信息以及安装在未知位置的AP的估计位置信息被用于终端的位置信息计算,因此,位置的精度 措施可以改善。
