Location estimation method and apparatus using access point in wireless communication system

Abstract

An operating method for a location estimation apparatus communicating with an access point (AP) in a wireless communication system according to an embodiment of the present invention comprises the steps of: receiving, from a second AP, a first received signal strength indicator (RSSI) signal having been measured at a first AP, and generating a first RSSI vector corresponding to the first RSSI signal; calculating a path loss exponent, using the distance between the first AP and the second AP and the first RSSI vector, and generating a second RSSI vector of each of multiple sub-areas divided from an entire area, using the path loss exponent; and generating a radio map of the entire area, using the first RSSI vector and the second RSSI vector.
