Title:
SMART ANTENNA PERFORMANCE TEST AND OPTIMIZATION METHOD, DEVICE, AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/133611
Kind Code:
A1
Abstract:
A smart antenna performance test and optimization method, device, and apparatus. The method comprises: first, calibrating respective channels of an installed smart antenna; configuring, according to a target performance parameter of the smart antenna, beamforming weights of the respective channels of the smart antenna; obtaining test signals received by a test terminal from various testing points; obtaining, according to respective test signals, a measured performance parameter of the smart antenna; comparing and analyzing the target performance parameter and the measured performance parameter; and adjusting, according to a comparison result, the beamforming weights of the respective channels of the smart antenna. The embodiment is utilized to optimize beamforming weights and coefficients to obtain accurate and optimal beamforming coverage conforming to an actual environment, reducing human intervention and engineering debugging in beamforming tests and optimization.
