Abstract:

The low-altitude economy is an emerging comprehensive economic form driven by low-altitude flight activities. Firstly, the industry driving forces of the low-altitude economy are studied, including four aspects: market, technology, policy, and regulation. Secondly, the research progress in the low-altitude field by standardization organizations such as ITU, 3GPP, IEEE, and CCSA is examined. Finally, in response to the technical challenges faced in air-ground networking, three commercial air-ground integrated communication networking solutions are proposed: single-carrier air-ground frequency-different scheme, dual-carrier air-ground frequency-different scheme, and dual-carrier air-ground frequency-same scheme, providing multiple options and possibilities for the development of low-altitude communication networks.

Key words: air-ground integration, low-altitude economy, air-ground networking scheme, low-altitude communication
