摘要： 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.
