Experimental throughput analysis and MIMO indoor propagation prediction for 802.11n system

Significant improvements in the quality and reliability of indoor WLAN connections are claimed for devices with MIMO technology using the recently developed standard 802.11n, which allows users to achieve theoretically up to 300-600 Mbps on a single transmission. This paper presents an analysis of a commercial 802.11n MIMO 2×3 dual band (2.4 & 5 GHz) system focusing on the operational throughput performance over an indoor environment with Line of Sight and Non Line of Sight scenarios. Although many authors have provided evidence on the effectiveness of this technology in field strength distribution, throughput or propagation-simulation environments, efforts on all parameters combined is limited. This paper also intends to elucidate the comparison of these metrics by evaluating a MIMO 2×3 dual band (2.4 & 5 GHz) system, focusing on physical measurements of the operational performance, in comparison with simulations of the field strength distribution over an indoor environment.
