一个在华为坐了6年“冷板凳”的专家

Core Viewpoint - The article discusses the development and commercialization of Sub1G Massive MIMO technology, highlighting the challenges faced and the innovative solutions discovered throughout the research process [2][3][17]. Group 1: Project Development - The Sub1G Massive MIMO project began with significant excitement but faced challenges due to the large size of antennas required for the low frequency [3][4]. - Initial research revealed that conventional designs could not meet the performance and deployment requirements, necessitating the search for new technologies [4][5]. - Two key technologies, Q technology and C technology, were identified as potential solutions to enhance antenna performance in tight spaces [5][8]. Group 2: Research Challenges - The project encountered setbacks when initial tests of Q technology showed a significant drop in performance when scaled to a network [6][7]. - A breakthrough occurred when traditional antenna designs were adapted, leading to improved performance metrics [7][15]. - Continuous collaboration with platform experts and iterative testing were crucial in overcoming deployment challenges and optimizing performance [15][17]. Group 3: Commercialization Efforts - The Sub1G 2.0 project faced difficulties in gaining approval due to a lack of immediate market opportunities, resulting in extensive proposal revisions and presentations [11][12]. - The launch of Sub1G 3.0 was expedited due to a novel U solution that effectively expanded the antenna's capabilities without increasing size [13][14]. - By the end of 2023, the market demand for Sub1G capacity intensified, leading to the successful establishment of a commercial technology project [17][19]. Group 4: Future Outlook - The company anticipates ongoing exploration in the Sub1G domain to meet evolving market demands for smaller, more efficient, and cost-effective solutions [19]. - The commitment to research and development is underscored by the belief that significant market-ready products will emerge from persistent efforts [19].
