Urban Outdoor MIMO Experiments with Realistic Handset and Base Station Antennas

—This work presents results for wireless outdoor MIMO transmission experiments at 2.68 GHz, which were conducted in an urban residential area, using realistic handset and base station antennas. Characteristic parameters of MIMO systems, obtained from measurements, were compared to theoretical results. From the comparison it could be concluded that the transmission of two spatial streams was well supported in the investigated 2 × 2 MIMO system, even with receive antenna element spacings as small as a quarter of the wave length. Comparing different receive antennas, the MIMO performance was found to be dominated by the received signal power rather than the spatial correlation.
