Abstract

This new location detection method uses LAN systems. The location of the user station is established using the received intensity at a user station of signals from wireless base stations. The method employs two unique concepts. 1) Instead of a discrete coordinate position to define the location of user station, the location is found by using a localized area. 2.) The learning algorithms based on LVQ (Learning Vector Quantization) are applied to process in location. As a result, our method provides more accurate positions compared with conventional Least Squares Method (LSM) methods in areas far from the base points.
