Movable and Reconfigurable Base Station Antennas for Intelligent Network

With the evolution of wireless communication toward intelligent and adaptive networks, traditional fixed base station antennas can hardly meet the dynamic requirements of flexible coverage, interference suppression, and efficient resource allocation. This talk presents the design, implementation, and performance evaluation of movable and reconfigurable base station antennas for intelligent networks. The proposed architecture integrates mechanical rotation adjustment and electrical reconfiguration to realize real-time tuning of radiation pattern and beam direction. By integrating the capabilities of manageable engineering parameters, fully adjustable beams, and automatic self-optimization, a network-driven intelligent control scheme is adopted to enhance system capacity. Experimental results demonstrate that the proposed antenna system effectively improves coverage performance, suppresses interference and reduces energy consumption, providing a promising solution for flexible and intelligent mobile communication networks.

Weihong Xiao received his Bachelor and Master degrees from the University of Electronic Science and Technology of China (UESTC), Chengdu, China, both in Electronic Engineering, in 2003 and 2006 respectively. Mr. Xiao has been with Huawei Technologies since 2006, where he is currently the CTO for Base Station Antenna and Director of C-TMG on Antenna Technology. Under his leadership, Huawei Antenna has ranked No. 1 in competitiveness for the past ten consecutive years. Meanwhile, Huawei has developed a series of cutting-edge technologies of FreSIP, SDIF and Metalens for the comprehensive improvement of RF efficiency, coverage efficiency and beamforming efficiency, leading the base station antenna industry into a new era of continuously improving its generalized efficiency. For example, Huawei BladeAAU Pro packaged the iF Design Award, Red Dot Design Award, and Best Mobile Network Infrastructure Award, while Huawei Green Antenna Series won GSMA GLOMO Award for Best Mobile Network Infrastructure 2024. He holds over 220 granted and pending US/WO/PCT/CN patents.
