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 2x3 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. Each scenario evaluates the performance of a MIMO system at 5 different locations for 20 MHz and 40 MHz bandwidth configurations. An additional experimental investigation on the throughput is described for Antenna Diversity (SISO, MISO, SIMO and MIMO) on scenarios operating at 5GHz and transmitting within a 20 MHz bandwidth. Results from this study show that at a range of 10m the throughput performance for channel bonding transmission (using 40 MHz bandwidth) for 2.4 GHz and 5GHz, was able to achieve the optimal values established by the standard 802.11n, that is 296 Mbps for Line of sight scenarios, as well as 250 Mbps for Non Line of Sight.
