Multiple transmitters and receivers can be used to provide high link capacity in future wireless systems. Herein, an analysis of indoor environment Multiple-Input-Multiple-Output measurements in the 5.8 GHz band is performed and the possible increase in capacity, utilizing multiple transmitters and receivers is examined. The investigation shows that in the measured indoor environment, the scattering is sufficiently rich to provide substantial link capacity increases. Furthermore, the effect of intra-element element spacing on the channel capacity is studied. Finally the possible Hiper-LAN/2 MIMO channel capacity, based on the measurements, is examined.
