广西移动建成全区首个地铁隧道5G 4.9GHz高频段覆盖示范工程

Core Insights - Guangxi Mobile has successfully established the first 5G 4.9GHz high-frequency coverage demonstration project in the subway tunnel of Nanning Line 1, addressing communication challenges in confined spaces and enhancing digital transformation in urban rail transit [1][5]. Group 1: Project Overview - The project significantly improves network speed, providing passengers with a "zero-lag" experience and setting a new paradigm for digital transformation in urban rail transit [1][5]. - The subway Line 1 serves as a vital transportation artery for Nanning, handling a daily passenger flow of approximately 300,000 [5][6]. Group 2: Technical Achievements - Guangxi Mobile's team utilized an innovative 4.9GHz high-frequency equipment and an eight-channel wall-mounted coverage solution, achieving a breakthrough average download speed of 396Mbps and a peak speed of 809Mbps, over three times the previous solution [5][6]. - The new system effectively resolves issues such as video lag and gaming delays, allowing passengers to enjoy high-bandwidth applications like 4K video streaming and cloud collaboration even during peak hours [5][6]. Group 3: Operational Impact - The upgrade not only enhances user experience but also transforms the operational management system of rail transit, enabling full-process digital transformation in areas such as fault handling, facility maintenance, and construction management [6]. - The integration of 4K HD monitoring and 3D modeling data allows for millisecond-level synchronization back to the command center, providing reliable technical support for precise decision-making [6].
