The widely applied location-based services require a high standard for positioning technology. With the development of the wireless communication technology, the positioning services based on Wi-Fi are increasingly demanded. To understand the positioning accuracy limits under a certain given Access Point topology and to be able to make design recommendations. This paper proposed a method for proper deployment of AP devices on the building of the electrical department in the university of technology and computing the measurements of the Received Signal Strength (RSS). Received Signal Strength measurement was obtained from different received points located within the targeted building. Many software can be used for the measuring of RSS values. In our work, it has been used Net Spot pro software. Net Spot is a software tool for wireless network assessment, scanning, and surveys, analyzing Wi-Fi coverage and performance. RSS reading were measured for four directions (North-South-East – West). It should mention that each RSS measurement obtained per each direction, is actually the average of 4 RSS measurement samples. This trend is to provide more accurate results than a single measurement Floor layout has been designed and imported to the software and used to allocate the measurements in the exact received point locations. The objective of this paper is to achieve full coverage area with less number of AP devices and reduce the total implementation costs.
With the rapid development in the field of communication networks, an indoor positioning system (IPs) has become extremely popular in recent years. In this paper, we compute the access points (AP's) localization to get the best coverage of the building that takes as a case study and administration of the network. The most interesting researcher topics were computing the Received Signal Strength (RSS) measurement and path loss of the signal. RSS and path loss measurement obtained from different received points distributed in different places of the building. The objective of this technique provides an overview of the available outputs of a standard Wi-Fi signal, which is the RSS from each Access Point. So, it is possible to get a list of the received power coming from all the APs covering the area where the received points are distributed in different locations. The results to determine the best direction at each received point was achieved using Wireless Insite. The methodology is applied over two steps, these are data collecting phase, and localization phase. The case study is implemented simulation results using 3D-Ray Tracing approach based wireless InSite software. This software is a suite of ray-tracing models and high-fidelity EM solvers for the analysis of site-specific radio wave propagation and wireless communication system. The aims of this paper finding the best result of the access points that coverage and transmit a signal to most received points to obtain the lowest cost of the localization method for indoor communication application.
