With the recent expansion of 3G and 4G networks and great popularity of smartphones, location-based applications in various smartphones have drawn great attention. At the same time, indoor positioning technology has emerged as well. There have been studies on the conventional indoor positioning techniques focusing on the triangulation technique which uses indoor WiFi signals. However, this triangulation technique is only available in the area where three or more mobile AP signals can be detected. This study examines the effect on positioning performances when new AP is added. It has also attempted to investigate the accuracy of AP position by localization algorithm and changes in the positioning results.
