As a result of analyzing the fire accident of the Jecheon complex that occurred at the end of 2017, there have been many casualties due to delays in checking the location information of isolated people. In order to prevent such an accident, various research has been conducted to estimate the location of requesters by means of detecting wireless communication information of mobile phones existing at disaster sites. The main concept is to detect an RF signal of a mobile phone at fire sites and, based on this, precisely estimate the location of the mobile phone on the LOS/NLOS. However, it is difficult to get visibility at fire sites due to smoke and the fire. Therefore, apart from estimating the location of requesters, a research is also needed to determine the direction of entry within fire sites. In this paper, we propose a method to determine a direction of entry to provide effective rescue activities using wireless communication information of mobile phones.
