华为宣布全国首个 4.9 GHz + F/A SUL 一体化基站示范区落地，小区边缘速率提升数倍

Core Viewpoint - Huawei, in collaboration with Tianjin Mobile, has successfully deployed the first integrated base station demonstration area in China based on 4.9 GHz and F/A frequency band SUL (Supplementary Uplink) technology, aimed at validating the capabilities of 5G-A networks in enhancing uplink transmission rates [1][5]. Group 1 - The demonstration project achieved a stable uplink speed of 20 Mbps at the edge of the network cell, representing several times improvement compared to the previous performance of the 4.9 GHz single frequency band [1][5]. - The solution integrates the 4.9 GHz main frequency band with the F/A frequency band for supplementary uplink into a single AAU (Active Antenna Unit) device, which is designed to reduce rooftop space usage and adapt to complex urban installation scenarios, achieving approximately 10% energy savings [3][7]. - The technology addresses the increasing demands for uplink speed and stability from applications such as live streaming and AI mobile devices, and provides a technical pathway for the smooth transition of certain spectrum resources from 4G networks to 5G-A [3][7]. Group 2 - Huawei announced the upcoming release of the new generation live streaming device "Huawei Portable WiFi X" in 2026, which will support high-definition live streaming scenarios in conjunction with the enhanced uplink network [4][9].
