en.Wedoany.com Reported - China Mobile Yunnan, in partnership with ZTE, pioneered the large-scale commercial deployment of 5G-A large uplink technology in Xishuangbanna on May 11, 2026, achieving a single-user peak uplink rate of up to 1Gbps+. According to C114 Communication Network, this deployment marks a new breakthrough in the uplink capability of commercial 5G-A networks, focusing on the core demand for surging uplink traffic in the AI era.
During the annual Water-Splashing Festival in Xishuangbanna, tens of thousands gather along the Lancang River for blessings, creating dense crowds. Self-media live streaming, high-definition short video sharing, and real-time interactive connections cause a sharp increase in network uplink traffic. High-density, high-concurrency, and high-interaction scenarios pose extreme challenges to network uplink capabilities. By integrating multiple cutting-edge 5G-A technologies such as radio frame structure optimization, uplink carrier aggregation, and large uplink base stations, Yunnan Mobile comprehensively enhanced uplink capacity while balancing user downlink traffic, fully unleashing network potential.
On the technical solution level, Yunnan Mobile pioneered the "1D3U" frame structure technology, doubling the uplink rate in key areas like the Water-Splashing Square and effectively supporting real-time short video backhaul. Yunnan Mobile simultaneously deployed intelligent computing boards, using AI to identify live streaming traffic in real time, improving resource scheduling efficiency by 30%. Leveraging the "AI + Wireless Operations Workbench," Yunnan Mobile achieved intelligent prediction, automatic optimization, and multi-agent collaborative scheduling, ensuring "zero lag, zero congestion, and zero failure" in key area networks.
Measured data shows that during the 2026 Xishuangbanna Water-Splashing Festival and the "May Day" holiday, uplink traffic in core scenic spots doubled compared to normal days. The 5G-A large uplink network provided stable, high-speed services such as HD live streaming and video calls for over 250,000 mobile users, guaranteeing a premium experience under high-density crowd conditions. The network also supported interactive performances by "humanoid robots," showcasing the deep integration of technology and culture.
On the industrial policy level, the "China Mobile 5G-A Super Uplink Action Plan," released during the Mobile World Congress in Barcelona in March 2026, clearly established a "3+2+3" uplink enhancement technology system. This system enhances network uplink performance by optimizing uplink timeslot configurations, flexibly utilizing spectrum resources, and improving terminal capabilities. GSMA simultaneously officially released the "Large Uplink Network Initiative," establishing an industry-unified standard of ubiquitous 20Mbps and peak 1Gbps. China Mobile has joined industry partners to complete field verification of key technologies such as 4.9GHz frame structure adjustment, SUL supplementary uplink, and uplink three-carrier aggregation, with measured uplink peak rates increasing to 750Mbps and edge rates to 20Mbps.
As the technical partner for this large-scale commercial deployment, ZTE has previously accumulated deep experience through multiple technical collaborations with Yunnan Mobile. In 2025, Yunnan Mobile and ZTE completed a live network pilot for application-responsive network cross-domain technology in the Dehong Dai and Jingpo Autonomous Prefecture, and jointly promoted the upgrade of wireless performance optimization from a traditional manual experience-driven model to a data-driven intelligent one. ZTE's 2025 5G Uplink Enhancement White Paper systematically elaborated on the large bandwidth and low latency requirements faced by 5G uplinks, as well as the challenges and solutions for high-frequency band deployment under the TDD standard. This deployment in Xishuangbanna represents the concentrated commercial network realization of years of technical synergy between the two parties.
Xishuangbanna, home to Yunnan provincial tourism landmarks like Gaozhuang Xishuangjing, features complex scenarios, dense user populations, and strong service demands, with a high penetration rate of 5G terminals and significant demand for uplink bandwidth. Previously, China Mobile's 5G-A three-carrier aggregation site was established in this scenic area in 2024. Following this upgrade, Xishuangbanna is transitioning from a cultural tourism destination to a smart city model. The large-scale commercial deployment of 5G-A large uplink will provide continuous technical support for the synergistic development of 5G-A and new AI services in Yunnan.
