Millimeter wave (mmWave) has been known to be the most promising technology for the future of wireless communication. It uses directional antenna for both transmitters and receivers to minimize its higher attenuation characteristics. Different localization approaches take the advantages of these directionality features in mmWave frequencies for different indoor environment. As a result, understanding the best position for AP's implementation has a huge effect on enhancing certain areas of network activity, maintenance, and coverage. In addition, establish the behavioral features of the wireless network. For localization purposes, the most used method was based on calculations of obtained signal intensity (RSS), which is commonly used in the wireless network. As well as it can be easily accessed from different operating systems. In this paper, we proposed an optimal AP localization algorithm based on RSS measurement obtained from different received points and by using mmWave bands of 28 and 39 GHz. This algorithm works as a complementary to the results obtained from 3D Ray tracing model based wireless InSite software. Four AP locations per each selected mmWave band have been included for algorithm investigation. Results obtained illustrate utility in selecting the appropriate position for the implementation of AP and based on the estimation of various parameters by the algorithm presented. The effects of different building materials and frequency sensitivity materials on signal propagation have been considered with specifying the optimum location for deploying AP. In addition, in this article, a channel characterized based on path losses was obtained for each AP position in each mmWave band as a validation of the algorithm's selection of the optimum location.
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.
