  • Patent number: 10256930
    Abstract: A testing method for testing mobile communication devices comprises measuring a three-dimensional antenna pattern of an active phased antenna array (AAS) of the mobile communication device, with the AAS being maintained at a specific beamforming alignment during the measurement. A predefined base fading profile is calibrated with the measured three-dimensional antenna pattern to obtain an optimized fading profile adapted to the specific beamforming alignment. A channel model for emulation of a base station is emulated on the basis of the optimized fading profile. The method further involves performing a receiver test on the mobile communication device using the emulated channel model. The testing method may in some embodiments be a radiated two-stage over-the-air (RTS-OTA) testing method.
