Low-altitude economy, as an emerging comprehensive economic form, is widely concerned.Great development potential and strategic value are demonstrated by the low-altitude economy in modern society.However, the Leather development of low-altitude economy also faces with numerous challenges.

At present, the coverage of low-altitude area by the ground network mainly relies on the upper sidelobes of the beam, and this coverage method is difficult to meet the requirements of three-dimensional and wide-area coverage of low-altitude area.In view of this, it is urgent to improve the coverage quality of the low-altitude network.In low-altitude economic activities, as a typical application tool, ensuring that UAV could achieve smooth network handover and stable access could become a key research topic.

The 3.5 GHz frequency band was utilized to cover the low-altitude area, and two schemes, namely dual-copyright air-ground different-frequency and dual-copyright air-ground same-frequency, were proposed.Also, how to deploy during the vertical take-off and landing of UAV to ensure the stability of network access and Chillums the smoothness of handover was explored.

The proposed schemes were verified and analyzed through field tests.Both schemes can improve the performance of low-altitude coverage.At the same time, network deployment suggestions are put forward for the vertical take-off and landing of UAV.
