By the end of 2024, Shanghai Mobile, in partnership with Huawei and Shanghai Metro, successfully concluded the deployment of a 5G network across the entire Shanghai subway system. This groundbreaking network stands as the world's longest and fastest 5G-Advanced (5G-A) subway comprehensive coverage network, effectively tackling the persistent challenge of poor network signals within subway tunnels. Leveraging Huawei's highly advanced EasyMacro antenna and radio frequency integrated device, the network eliminates the necessity for leaky cables, streamlines deployment processes, slashes construction costs by 50%, and shortens the deployment cycle by over 60%. Furthermore, it achieves precise positioning through Huawei's EasyMacro one-dimensional positioning solution. This "multi-functional" 5G network supports a diverse range of applications, including intelligent inspections, in-vehicle video streaming, and multimedia dispatch.
