Recently, a media research initiative themed "Empowering Networks, Revitalizing Liaoning, and Shaping the Future with Intelligence" was launched, organized by the Ministry of Industry and Information Technology's News and Publicity Center and the Liaoning Provincial Communications Administration. This activity focuses on Liaoning's new information infrastructure. Representatives from central, industry-specific, local Liaoning, and self-media outlets gathered in the region to visit benchmark application sites of China Unicom's Liaoning branch in cities like Shenyang and Dalian, exploring practical examples of digital revitalization in Northeast China.
Digital information infrastructure forms the core foundation for Liaoning's comprehensive revitalization. Following the national "Signal Enhancement" initiative launched by the Ministry of Industry and Information Technology and the "Signal Enhancement, Unblocking Liaoning" action led by the Liaoning Provincial Communications Administration, China Unicom's Liaoning branch, upholding its responsibilities as a central state-owned enterprise, has coordinated upgrades across five dimensions: coverage, user experience, technology, support, and application. On one hand, it meticulously refines the network hardware foundation to comprehensively enhance wireless network capacity and service quality. On the other hand, it deeply explores the value of digital-intelligent integration, implementing digital solutions for government and enterprise sectors across industries, transforming high-quality network resources into governance efficiency and industrial momentum, thereby supporting the construction of a digital Liaoning with a high-quality, ubiquitous communication network.
Refining the Network Foundation, Multi-Dimensional Upgrades Fortify Communication Infrastructure
China Unicom's Liaoning branch has tackled challenges simultaneously across four dimensions—spatial coverage, user experience, cutting-edge technology, and emergency support—systematically addressing network weaknesses to build a stable, high-speed, and intelligent ubiquitous communication network. In terms of network coverage, the company has established a data-driven mobile network operation system, integrating multi-source data from networks, users, and markets to precisely locate issues. Relying on a "four-dimensional value model," it allocates construction resources based on local conditions, focusing on strengthening weak signal areas such as old residential districts, underground tunnels, urban commercial zones, and remote offshore islands. In urban areas, RIS (Reconfigurable Intelligent Surface) technology is used to cost-effectively eliminate signal blind spots caused by building obstructions. In Dalian's coastal areas, innovative solutions like sea-surface remote extension and 2.1G 8T ultra-long-range coverage have been deployed, overcoming challenges like complex island construction and sea wind corrosion. Over 150 marine base stations have been built, achieving continuous signal coverage up to 50 kilometers offshore, with 5G coverage on major islands in Changhai County exceeding 99%.
Focusing on user experience, a user-centric service system has been established, strictly implementing a "1211" service response mechanism. Concurrently, AI algorithms are used to build user perception profiles, shifting from passive fault repair to proactive prediction and optimization. Network resources are dynamically allocated for high-frequency scenarios like live streaming in tourist spots, commuting internet access, and store QR code scanning, effectively avoiding lag and latency issues even during peak hours, continuously enhancing public satisfaction with internet access.
Technological innovation is the core driver for network quality improvement. China Unicom's Liaoning branch is fully advancing the commercial deployment of 5G-Advanced (5G-A), millimeter-wave, and integrated sensing and communication technologies, implementing several pioneering demonstration projects in Northeast China. Shenyang Metro Line 1 has established the region's first 5G-A 10-gigabit demonstration line, solving signal loss issues in enclosed tunnel spaces with peak rates exceeding 10 Gbps. Dalian's Xinghai Square has fully activated 5G-A, integrating 200 MHz of ultra-large spectrum bandwidth, achieving downlink peak rates up to 2 Gbps. Paired with AI computing boards that intelligently identify high-uplink-demand services like live streaming, simultaneous outdoor live broadcasts by hundreds of people remain smooth. Millimeter-wave integrated sensing and communication technology is used to establish low-altitude electronic fences, providing a novel technical path for refined urban governance.
Simultaneously, a dual guarantee system of "daily operation maintenance and emergency baseline protection" has been constructed. For large-scale events and holiday crowds, digital indoor distribution systems and multi-sector base stations are deployed at venues like Shenyang's Tiexi Stadium, urban commercial zones, and popular tourist spots. Combined with 7x24 online monitoring and intelligent bandwidth scheduling, these support tens of thousands of users in simultaneous HD live streaming and online interaction. Facing extreme situations like disruptions to roads, power, and transmission ("triple break"), a fallback solution of "ultra-high fortress stations + emergency network optimization" is established. Under the coordination of the provincial communications administration, 5G inter-network roaming is achieved in disaster-affected areas, firmly safeguarding the communication lifeline for disaster relief and public livelihood contact.
The solid results of network construction have gained national-level recognition. In the 2025 Ministry of Industry and Information Technology's national mobile network quality assessment, China Unicom's Liaoning branch won multiple awards. Shenyang was awarded the comprehensive operator prize, while specific scenarios like the Beijing-Harbin high-speed railway, Dalian medical institutions, and Anshan transportation hubs received specialized awards, certifying the network's comprehensive strength nationally.
Deepening Digital-Intelligent Application Deployment, Empowering All Industries Through Digital Transformation
The high-quality network foundation must ultimately serve the real economy and social governance. Leveraging the upgraded high-speed ubiquitous network, China Unicom's Liaoning branch focuses on five key government and enterprise sectors—government affairs, manufacturing, education, maritime, and cybersecurity—to create benchmark projects. Through scenario-based digital implementation, it completes the upgrade of application value, truly transforming network capabilities into developmental outcomes.
In the government affairs sector, the company is constructing the core foundation for the provincial digital government, building a platform for the full lifecycle management of government data, serving as the central hub for data flow and services across the province. It integrates large language models, blockchain, and big data technologies to upgrade the "12345" government service hotline. Leveraging massive datasets on public livelihood, the hotline is transforming from a traditional call center into a grassroots governance hub. Digital tools are implemented for scenarios like community profiling, specialized governance of public issues, and major incident response, efficiently resolving public concerns and continuously optimizing the business environment to enhance the modernization level of grassroots governance.
In the industrial intelligent manufacturing sector, China Unicom's Liaoning branch, as early as 2019, collaborated with a Shenyang automaker to build the world's first 5G digital factory. A 5G industrial private network covers the entire production process—stamping, welding, painting, and final assembly—with over 40 innovative applications deployed. Core scenarios like 5G+AI quality inspection and intelligent logistics were created, resulting in six globally leading technological achievements. The low-latency, high-reliability 5G network breaks down data silos in the workshop, with intelligent detection replacing manual inspections.
