摘要

低空经济在现代社会中展现出巨大的发展潜力和战略价值。然而，低空经济的发展同样面临着诸多挑战。目前，地面网络对低空的覆盖主要依赖于波束的上旁瓣，这种覆盖方式难以满足低空立体、广域覆盖的需求。鉴于此，迫切需要对低空网络的覆盖质量进行提升。在低空经济活动中，无人机作为一种典型的应用工具，确保无人机能够实现网络的平滑切换和稳定接入，成为一个关键的研究议题。利用3.5 GHz频段覆盖低空，提出双载波空地异频和双载波空地同频两种方案，并探讨在无人机垂直起降过程中如何部署以保障其网络接入的稳定性与切换的平滑性。通过现场测试对所提方案进行了验证与分析，两种方案均可以提升低空覆盖的性能，同时针对无人机垂直起降提出了网络部署建议。

Abstract

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 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-carrier air-ground different-frequency and dual-carrier 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 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.
