The "Four Networks" of the Low-altitude Economy

In the current era of rapid development, the low-altitude economy is gradually becoming a new economic growth pole. And the key to promoting the development of the low-altitude economy lies in the construction and improvement of the "Four Networks".

I. Facility Network: Consolidating the Foundation of the Low-Altitude Economy The facility network, as the physical infrastructure of the low-altitude economy, is like a solid cornerstone, providing indispensable hardware support for low-altitude flight. It encompasses a wide range of facilities such as low-altitude take-off and landing stations, transfer facilities, energy stations, emergency landing sites, parking facilities, maintenance facilities, and flight test sites.

The existence of these facilities ensures the safety, efficiency, and convenience of low-altitude flight. Taking electric vertical take-off and landing aircraft (eVTOL) as an example, the continuous improvement of the facility network has created favorable conditions for its wide application. With the continuous progress of technology, the facility network will continue to be upgraded to enhance the service capabilities of low-altitude flight and lay a more solid foundation for the vigorous development of the low-altitude economy.
II. Air Connectivity Network: Building a Bridge for Low-Altitude Information The air connectivity network, as the key information infrastructure of the low-altitude economy, meets the urgent needs for low-altitude perception and communication. It covers multiple aspects such as communication facilities, navigation facilities, surveillance facilities, and meteorological facilities. Through digital means, the air connectivity network realizes comprehensive perception, real-time monitoring, and precise control of low-altitude flight.

The application of 5G-A integrated sensing and communication technology and the Beidou Navigation System will further enhance the communication capabilities, navigation accuracy, and surveillance range of the air connectivity network. This not only improves the safety of low-altitude flight but also provides strong support for the collection, analysis, and application of flight data, injecting new vitality into the intelligent development of the low-altitude economy.
III. Air Route Network: Mapping the Route of Low-Altitude Flight The air route network, as the navigation support infrastructure of the low-altitude economy, provides precise navigation and planning services for low-altitude flight. It includes rich digital resources such as low-altitude digital airspace maps, airspace representations, digital twins, 3D maps, knowledge bases, and rule bases.

The construction of the air route network simplifies the flight approval process and improves the utilization efficiency of airspace resources. With the continuous improvement of the air traffic management system, the air route network will play an even more important role in the low-altitude economy. It is like a detailed map, guiding low-altitude aircraft on the accurate course and facilitating the efficient and orderly development of the low-altitude economy.
IV. Service Network: Creating a Window for Low-Altitude Services The service network, as the digital management and service system and comprehensive supervision platform of the low-altitude economy, is customer-oriented and meets the regulatory safety requirements and enterprise flight requirements. It consists of a low-altitude monitoring system, a low-altitude flight service system, and a low-altitude flight control system.

Through digital means, the service network realizes the overall planning, coordination, management, and allocation of low-altitude flight, providing one-stop management services for various low-altitude flight activities. Its construction not only improves the safety and reliability of flight but also provides strong support for the optimization and upgrading of flight services. In the future, the service network will develop in a more convenient and efficient "one-stop" direction, opening a window for users to access high-quality flight services.
V. Collaboration of the "Four Networks": Creating the Future of the Low-Altitude Economy The "Four Networks" of the low-altitude economy have respectively constructed a complete ecological system from four aspects: infrastructure, communication connectivity, route planning, and service delivery. They are interdependent and cooperate efficiently to jointly promote the safe, intelligent, and commercial development of the low-altitude economy.
The facility network provides hardware guarantees for low-altitude flight, the air connectivity network enables the smooth transmission of information, the air route network plans precise flight paths, and the service network provides high-quality management services. Only when these "Four Networks" work closely together and develop in coordination can the huge potential of the low-altitude economy be fully unleashed and a bright future in the low-altitude field be created.

In the future development, we should continue to increase investment and construction efforts in the "Four Networks" of the low-altitude economy, continuously promote technological innovation and management innovation, and make the low-altitude economy a new engine for economic growth, bringing more convenience and opportunities to people's lives.
