MIMO OTA testing on WiFi devices and 3D channel modeling in multi-probe anechoic chamber systems

Over the air testing of multiple antenna systems has attracted great attention in recent years. The research and standardization work have been focused on evaluating user equipment (UE) in two dimension (2D) radio propagation channel models. This paper proposes two future direction of over the air testing: 1) performance evaluation of WiFi devices under realistic propagation scenarios and 2) 3D radio channel characterization in multi-probe OTA systems. The basic ideas and some simulation results have been provided.
