Optimization of Wi-Fi access point placement in an indoor environment

Abstract

In this paper, we propose an optimization approach for designing WLAN networks in an Indoor environment. This approach integrates all relevant parameters to find the optimal placement of access points, there optimum settings (transmission power, azimuth, radiation patterns, etc.) and the optimal allocation of channels while maximizing the coverage, minimizing the interference and minimizing the number of access points to install. Our approach was evaluated when planning a WLAN 802.11 an with a 5GHz band and 20MHz bandwidth on a 5-story building. The results show the effectiveness of our approach to quickly plan a high quality WLANs.
