How to automatically generate a fingerprint database for an indoor wireless positioning

The present invention relates to a fingerprint database automatically creates a method for indoor wireless positioning. The invention For this purpose, determines the intensity calculation method of signals transmitted from multiple access points, and then calculates a signal strength of the intersection each of a plurality of vertical grids and the horizontal grids set in an indoor area, position information of the intersection point and the output by using the signal strength and provides the fingerprint database creation method for creating a database table. The present invention is a communication module for performing communication with the one or more access points and a receiving terminal; By calculating the signal strength for a particular position using the intensity calculation method, the environment analysis module that generates a fingerprint database table; And a fingerprint database table provides an environment analysis apparatus comprising a fingerprint database to store. According to the present invention, it is possible to reduce the time and manpower to build a fingerprint database, even if the interior structure change has an effect capable of easily building a new fingerprint database.
