As China celebrates the sixth anniversary of 5G commercialization, the fusion of artificial intelligence with next-generation connectivity is unlocking unprecedented industrial transformation, which is of crucial importance to the upgrade of the country’s sprawling industrial economy, corporate executives and experts said.
What began as a high-speed network blueprint has now evolved into a dynamic ecosystem where 5G-Advanced, or 5G-A, technology bridges today’s smart applications and tomorrow’s 6G ambitions — with China at the forefront of this global shift, they added.
Globally, 5G has achieved staggering adoption, surpassing 2 billion connections by 2024 — half of which are in China, the first market to hit 1 billion 5G users, according to a report from the GSMA, an industry group representing the world’s largest mobile phone operators.
By 2030, 5G is projected to comprise 57 percent of total mobile connections globally, with China’s robust network laying the foundation for industrial digitization, the GSMA said.
Yet, like a vast highway system needing traffic control, 5G’s potential hinges on intelligent orchestration. Enter AI: generative models and machine learning are becoming 5G’s “digital brain,” optimizing everything from factory floors to low-altitude drones, experts added.
In real-world applications, this synergy has taken center stage. Humanoid robots perform precision tasks, autonomous taxis navigate urban grids, and AI devices redefine human-machine interaction — all powered by 5G-A’s low latency and AI’s real-time decision-making.
He Biao, general manager of China Mobile, said, the company “will trial 6G technologies on its 5G-A infrastructure, and promote the integrated research and development of the two”.
As an important upgrade of 5G, 5G-A networks theoretically deliver tenfold improvements in peak data rates and connection density compared to 5G.
More importantly, 5G-A base stations have integrated sensing and communication capabilities. They not only handle voice and data transmission, but also can function as distributed radar systems, enabling real-time detection of airborne objects within their coverage zones, China Mobile said, adding that it is testing such a system to facilitate the development of the low-altitude economy, such as drone delivery in Shenzhen, Guangdong province.
As a global pioneer in commercializing 5G-A technology, which plays a key role in bridging 5G to 6G, China has already deployed such networks in over 300 cities, according to the Ministry of Industry and Information Technology (MIIT).
Meanwhile, more than 30 provincial-level regions in China have launched 5G-A service packages, with subscribers surpassing 10 million.
The progress came after China solidified its global leadership in 5G deployment, with the total number of 5G base stations reaching 4.44 million, achieving full 5G coverage in all townships and 90 percent penetration in administrative villages, according to the latest data disclosed by the MIIT in June.
China’s 5G applications now span 86 out of 97 national economic sectors, with over 138,000 real-world use cases. Key sectors such as manufacturing, healthcare, and energy are rapidly digitizing, supported by more than 18,500 “5G + industrial internet” projects nationwide, the MIIT said.
While 5G matures, its enhanced sibling, 5G-A, coupled with AI, is also reshaping industries. In the industrial sector, 5G-A’s ultra-low latency and high bandwidth are enabling precise perception and decision-making for robots. Real-time data processing via 5G-A supports closed-loop “sense-decide-act “operations, reducing high-risk work hazards while boosting efficiency and safety, according to Huawei Technologies Co.
For robots to truly integrate into industrial production and everyday applications, low latency is the basic requirement, and collaborative decision-making is the key to commercial applications, said Chang Lin, CEO of Leju Robotics.
With the help of sound networks, AI is also helping companies boost efficiency. State Grid Zhejiang Electric Power Co Ltd’s information and communication branch recently unveiled its self-developed “CoolGood” AI code review agent, providing an innovative solution to a critical industry challenge. Facing the inefficiency of traditional manual “bug hunting” code reviews, the company has now achieved “near real-time diagnosis” of system code through AI. This breakthrough has doubled the efficiency of electricity billing calculations and increased the operational efficiency of core power grid business systems by a factor of ten.
Ye Wei, code review lead at the company, emphasized the critical importance of code quality: “If we compare the digital system to the neural network supporting the physical grid infrastructure, code is the neuron. Its quality directly impacts the safety, stability, and operational efficiency of the entire power grid.”
However, the company faced immense pressure reviewing billions of lines of code — a daunting task akin to “finding a needle in a haystack”.
Challenges included insufficient technical expertise, a shortage of skilled personnel, and the sheer volume of code, which led to a critical impasse: code reviews were often “unclear, unmanageable, and unfinishable”. This bottleneck resulted in high system resource consumption, slow business response times, and poor user experience.
The key to breaking this deadlock was the deep empowerment provided by the Guangming Power Large Model. This industry-specific large model, developed by State Grid Corp of China and featuring 100 billion parameters, integrates foundational capabilities from models like DeepSeek. Utilizing “incremental pre-training plus industry fine-tuning”, it has fundamentally transformed code review from labor-intensive “manual faultfinding” to efficient “AI-powered intelligent diagnosis”.
This “super brain” now provides robust support for the secure operation of the power grid, the integration of renewable energy sources, and the continuous improvement of power supply services. “The ‘Cool-Good’ agent represents a significant leap forward in leveraging AI to ensure the reliability and efficiency of critical national energy infrastructure,” Ye said.
The synergy between 5G-A’s wide coverage and AI route optimization is also enhancing efficiency and cutting costs. In autonomous driving, 5G-A’s sub-meter positioning merges with satellite navigation to enable cm-level vehicle precision — critical for parking and highway autonomy, Huawei said.
These innovations aren’t just incremental. They are laying 6G’s groundwork. Features like AI-native networks and space-terrestrial integration mirror 6G’s vision of ubiquitous, self-optimizing connectivity, experts added.
Xu Zhijun, rotating chairman of Huawei, said the telecom market has entered a mature phase, yet change is omnipresent. By identifying shifts and capturing growth-driven demand, the industry can fuel further expansion.
Xu said more efforts can be made to boost the supply and consumption of high-definition videos through coordinated efforts across the entire ecosystem, and to bring 5G to every car for new growth in intelligent connected vehicles.
According to a forecast by the China Industry Innovation Alliance for the Intelligent and Connected Vehicles, 5G-connected vehicles will account for 30 percent of all cars sold in China in 2025, with penetration expected to rise steadily to 95 percent between 2026 and 2030.
Xu said autonomous vehicles must be capable of independent perception and decision-making during self-driving operations. While both the vehicle cabin and the car itself require network connectivity, their needs differ, as do their business models. Therefore, these systems should operate independently, each maintaining its own connection.
“The industry must seize this growth opportunity in intelligent connected vehicles,” Xu added.
According to Huawei, commercially, experience-driven monetization is key to 5G-A’s success. By translating network capabilities into premium user experiences — such as cloud gaming and multi-angle sports streaming — 5G-A enables innovative payment models. This “pay-for-experience” trend is reshaping consumption and unlocking new value.
But challenges still exist. Wu Hequan, an academician of the Chinese Academy of Engineering, said that in recent years, emerging applications such as augmented reality and the low-altitude economy have created growing demand for high uplink bandwidth. However, current 5G networks face shortcomings in insufficient uplink speeds.
According to Wu, while China’s mobile networks have achieved remarkable progress in downlink speeds — with 5G being seven times faster than 4G and 5G-A 10 times faster than 5G — the uplink speeds still significantly lag behind downlink performance.
Vivek Badrinath, director-general of GSMA, said the past year has seen major strides in 5G and AI worldwide. Moving forward, GSMA will deepen collaboration with Chinese telecom carriers to seize 5G-A’s opportunities in enhanced performance and system efficiency to scale AI in manufacturing, ports and beyond.
The economic impact is staggering. GSMA forecasts 5G and 5G-A will generate $1 trillion in value by 2030. In China, early adopters like China Telecom showcase the potential. Their 5G-AI-satellite hybrid networks now support more than 200 low-altitude economy projects, from drone logistics to emergency response.
Yang Jie, chairman of China Mobile, the world’s largest telecom carrier, highlighted the dawn of the “AI plus era”, in which AI outperforms humans in tasks like image recognition and complex reasoning.
“Silicon-based lifeforms, such as AI devices, connected vehicles and robots, will soon outnumber humans,” Yang said. “AI presents unprecedented opportunities. China Mobile aims to be a provider, aggregator and operator in this new era,” he added.
As AI breathes life into 5G and 5G-A accelerates toward 6G, China’s blueprint offers a global case study. True innovation thrives when connectivity and intelligence converge — not just in labs, but in the lived realities of factories, skies, and cities. At this crossroads, the next decade of digital transformation is being written, experts added.
Advances in 5G transforming biz
Application of tech enhances innovation, production
On the factory floors of a leading appliance manufacturer in Europe, a quiet revolution is underway. China Unicom’s 5G network has transformed operations at this zero-carbon smart facility, where the marriage of ultra-low latency connectivity and advanced production lines management technology has yielded remarkable results: a 30 percent reduction in product defects, 12 percent increase in production output, and annual operational savings exceeding $100,000.
This success story is being replicated across continents, from a mine in Southeast Asia where a single operator can now remotely control up to six heavy machines simultaneously, to smart ports in China where efficiency gains are rewriting operational playbooks.
At the heart of this transformation is China Unicom’s innovative application of 5G networks and artificial intelligence technologies. The recent Mobile World Congress Shanghai 2025, held in late June, served as the launchpad for China Unicom’s next strategic evolution with the introduction of the U PLUS SMART system.
The system deeply integrates artificial intelligence into connectivity, communications, computing, and intelligent digital applications, and is designed to enhance product capabilities, accelerate technological innovation, and expand multi-scenario applications, delivering smarter, more efficient, and secure service experiences, China Unicom said.
Zhu Hanwu, deputy general manager of China Unicom, said: “In the era of intelligence, China Unicom is deeply implementing an integrated innovation strategy, positioning internationalization as a new growth driver for the company’s development. Guided by technological innovation and driven by open cooperation, the company is continuously enhancing its global operations.”
He outlined a comprehensive three-pillar strategy positioning the company at the forefront of global digital transformation.
The approach begins with building hyper-connected foundations through the convergence of terrestrial networks with satellite and marine cable systems. “We are willing to work with global partners to leverage their respective resource advantages, continuously improving global network accessibility and intelligent computing resource supply capabilities,” Zhu said.
Meanwhile, China Unicom is delving into industry scenarios to jointly empower global industrial transformation. The company will continue to leverage its integrated operational strengths in the internet of things, connected vehicles, and industrial internet to support more Chinese enterprises in going global and more international enterprises in entering China, creating more globally influential benchmark industry applications.
Moreover, focusing on areas such as smart living and smart mobility, China Unicom will accelerate the development of competitive products and platforms to drive the prosperity of industry chain terminals, content, and applications, Zhu added.
In late May, China Unicom (Europe) officially inaugurated its regional call center in Bucharest, Romania, marking a significant enhancement of its local service capabilities.
Xue Wenxia, general manager of China Unicom (Europe) Operations Ltd, emphasized the company’s commitment to open cooperation in driving digital transformation across the continent. “This facility represents our investment in localized support as we accelerate intelligent, internationalized services for European clients,” Xue said.
The expansion follows last November’s launch of China Unicom (Middle East) Operations Ltd in Dubai, United Arab Emirates. Both developments underscore China Unicom’s strategy to strengthen global connectivity infrastructure amid growing demand for cross-border digital services.
Markus Borchert, CEO of Nokia Shanghai Bell, a joint venture of Nokia Corp and State-owned investment firm China Huaxin, said China’s big three telecom carriers — China Unicom, China Mobile and China Telecom — all attach great importance to the business of helping Chinese companies venture out into overseas markets.
According to him, Hong Kong serves as a strategic gateway for their cross-border digital initiatives.
Xiang Ligang, director-general of the Zhongguancun Modern Information Consumer Application Industry Technology Alliance — a telecom industry association — said China Unicom’s fusion of cutting-edge connectivity solutions with practical AI applications offers a compelling blueprint for operational excellence in the digital age.
“China Unicom is an example of how Chinese tech companies are leveraging their pioneering solutions with the characteristics of foreign markets to solve practical problems,” Xiang said.
