The performance of voice, video and data streaming applications using the recently developed standard 802.11n with its MIMO antenna options, strongly depends on the nature of the environment. Although many authors have provided evidence on the effectiveness of this technology in field strength distribution, throughput or propagation-simulation environments, work linking all of these parameters is limited. This paper provides a comparison of metrics for a 2×3 dual-band MIMO system operating at 2.4 and 5 GHz in a typical office building, obtained using a commercial wireless router. The measurements are consistent with simulation results obtained using a 3D Shoot and Bounce Ray (SBR) software.
