Abstract

This work proposes a Mobile Station (MS) location method that uses a single Base Station (BS) of the cellular network. The method is capable of analyzing the various transmission paths and identifying whether or not there is an LoS path, thus making it possible to automatically determine and apply a suitable location method. The proposed method can be divided into three steps: (1) verification of the existence of an LoS path, (2) application of the appropriate geometric method for each type of condition (LoS or NLoS), and (3) fine-tuning step that determines the the precise location of MS. Simulations and comparisons made with related works show that the method proposed here is fast and effective, presenting submetric precision.
