Estimating signal strengths in indoor wireless systems in order to deliver a cost-effective solution optimizing the performance of the network

Nowdays, indoor networks are getting more popular and its use is widely spread, growing its share into the international market. At the beginning, this solution was not popular and therefore suitable, because of its low rate speeds. Thereby, important institutes as IEEE and Wi- FI Alliance worked together to develop a standard: IEEE 802.11x. The purpose of this paper is to show different methods for reducing the infrastructure deployment costs of wireless networks, specifically for systems that are willing to transmit very high data rates.Proper AP placement is necessary to provide adequate signal coverage and also to minimize co-channel coverage overlap. In this document, we present the test-bed used in our lab and the procedure and methodology we have created (modified) to achieve accurate measurements. We describe a procedure for carrying out the estimation of AP coverage patterns in order to eliminate the need to re-measure coverage patterns for every candidate combination of AP locations. It is expected to obtain a difference no bigger than the 3 dB between the estimated signal strength and measured signal strength
