Abstract: The rapid development of the low-altitude economy poses challenges to the expansion of wireless coverage for the low-altitude airspace. In the future, utilizing existing terrestrial and space-air communication systems to provide communication coverage for the low-altitude airspace and combining technologies such as intelligent reflecting surfaces to assist low-altitude communication will be a research hotspot. This paper combs the low-altitude three-dimensional wireless coverage technologies and points out the future research directions of the low-altitude economy. It is believed that low-altitude communication will integrate sensing and positioning functions, enhancing the management, control, and service capabilities for the low-altitude airspace. This will achieve intelligent interconnection and intelligent coordination in the low-altitude area, and further promote the development of the low-altitude economy.
