China Tower operates millions of 5G base stations nationwide, forming the backbone of China's digital and industrial infrastructure.

China Tower is the primary provider of telecommunication infrastructure in China, managing over 4.7 million 5G base stations as of late 2025, making it the largest 5G network globally . These base stations are primarily shared among state-owned telecom operators, including China Mobile, China Telecom, China Unicom, and China Broadnet, with an average of 1.65 tenants per tower, reflecting efficient colocation and resource utilization .

Technological Capabilities

China Tower's base stations support 5G connectivity, enabling high-speed, low-latency communication essential for emerging technologies. They facilitate applications in industrial IoT, AI, and smart city management, such as real-time monitoring of chemical plants for safety and environmental compliance . The network also underpins intelligent connected vehicles, BeiDou satellite applications, and low-altitude information infrastructure, demonstrating versatility beyond traditional mobile communication .

Expansion and Future Plans

China continues to expand its 5G infrastructure, with plans to construct over 4.5 million additional 5G base stations in 2025, alongside trials for 10-gigabit optical networks and enhancements to computing power centers to support AI growth . This expansion positions China to lead in 6G research, with field test networks already demonstrating 6G-level transmission capabilities using existing 4G and 5G platforms .

Economic and Industrial Impact

China Tower's infrastructure is a critical pillar of the digital economy, enabling industries to leverage real-time data, AI analytics, and IoT platforms. For example, in Jiangsu Huai'an Industrial Park, 5G networks allow continuous monitoring of industrial processes, improving safety and operational efficiency . The company's revenue in 2022 reached $13.4 billion, with significant contributions from tower leasing and indoor distributed antenna systems, reflecting the commercial viability of its extensive network . In summary, China Tower's communication base stations are highly advanced, widely deployed, and strategically important, supporting both consumer connectivity and industrial digital transformation while laying the groundwork for future 6G technologies.
