Core Viewpoint - The development of the low-altitude economy relies on the support of low-altitude network communication and perception capabilities, with China Unicom actively building a digital foundation through five-network integration to foster innovative capabilities in low-altitude scenarios [1][2]. Group 1: Low-altitude Economy Infrastructure - China Unicom is constructing a "1+1+3+N" low-altitude capability system, which includes an integrated low-altitude smart network, a fusion of spatiotemporal big data, and three core platforms for safety regulation, airspace management, and smart low-altitude applications [1]. - The company emphasizes that traditional operators only provide communication pipelines, while low-altitude operations require centimeter-level positioning, real-time weather warnings, and obstacle avoidance decision-making [1]. Group 2: Data and Service Capabilities - China Unicom has made significant investments in edge computing and terminal computing, achieving data centralization across 31 provinces, positioning itself as a leader in data governance in China [2]. - The company has developed a public and industry data fusion computing infrastructure, accumulating high-quality datasets across over 10 industries, totaling 400 terabytes [2]. Group 3: Cost Efficiency and Operational Advantages - The operational cost for a logistics company building its own low-altitude network is 28 yuan per kilometer, while China Unicom's project in Zhejiang achieves a cost of only 9.7 yuan [2]. - In a project for the Yunnan power grid inspection, China Unicom reduced data processing latency from 3 seconds to 200 milliseconds by establishing edge computing nodes [2]. Group 4: Application Scenarios - In Longyan, Fujian, the efficiency of blood transport via drones has improved by 150% [2]. - In Zhengzhou, the company has implemented automatic inspection with "instant recognition" for heating pipeline networks [2]. - Cross-border island logistics testing has also been initiated [2].
