Abstract: This paper presents results from the measurement in indoor conference scenario at 3.5 GHz and 6 GHz. The measurement was performed by using multiple-input multiple-output (MIMO) antennas including uniform planar array (UPA) at transmitter end (Tx) and omnidirectional array (ODA) at receiver end (Rx). Two cases including UPA on the wall and the ceiling, have been measured and comprehensive propagation characteristics have been investigated in detail. Based on the measurement, delay and spatial parameters are analyzed and then compared with the standard model. The delay spread measured shows smaller value than standard model due to the small size of the scenario and the elevation angle spread is presented for establishing threedimensional (3D) channel model. Further, the capacity performances of the channel in different cases are evaluated, and the results indicate that the system with transmitter antenna mounted on the wall performs better.
