Measurement of MIMO Capacity in a Hallway at 2.4 GHz

This paper reports measurements of the capacity of a 2.4 GHz 4times4 MIMO system in which both ends of the wireless link are located in a hallway. This scenario is of interest due to the increasing mobility of ISM-band wireless devices, and because hallways have previously been reported to create difficulties for MIMO propagation. The capacity along horizontal and vertical cuts through the center of the hallway is found to be between 6 bps/Hz and 12 bps/Hz for a reference signal-to-noise ratio of 10 dB and a range of 12 m. Capacity in the horizontal plane was observed to be position-dependent and lower on average, due in part to a reduction in field strength with increasing distance from the center of the hallway. Also, it is inferred that the fading statistics are probably different in the vertical and horizontal cuts
