METHOD FOR AUTOMATIC GENERATION OF FINGERPRINT DATABASE FOR INDOOR WIRELESS LOCATION

摘要

A method of automatic generation of fingerprint database for indoor radio determination at low cost is provided to develope database and reduce a time and a worker for developing database by using an environment analysis tool. A signal strength calculating formula produces signal intensity transmitted from an AP(Access Point) more than one installed at indoor space(S210). A plurality of vertical lattices and horizontal gratings are set up in the indoor space(S220). The signal intensity received from AP is calculated in each intersection point of the horizontal grating and vertical lattice(S230). A fingerprint data base table is generated by using the location information of the intersection point and the signal strength of AP(S240).
