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

Abstract

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.
