UAV-Assisted Wireless Communications: An Experimental Analysis of A2G and G2A Channels
International ICST Conference on Simulation Tools and Techniques(2023)
摘要
Unmanned Aerial Vehicles (UAVs) offer promising potential as communications
node carriers, providing on-demand wireless connectivity to users. While
existing literature presents various wireless channel models, it often
overlooks the impact of UAV heading. This paper provides an experimental
characterization of the Air-to-Ground (A2G) and Ground-to-Air (G2A) wireless
channels in an open environment with no obstacles nor interference, considering
the distance and the UAV heading. We analyze the received signal strength
indicator and the TCP throughput between a ground user and a UAV, covering
distances between 50 m and 500 m, and considering different UAV headings.
Additionally, we characterize the antenna's radiation pattern based on UAV
headings. The paper provides valuable perspectives on the capabilities of UAVs
in offering on-demand and dynamic wireless connectivity, as well as highlights
the significance of considering UAV heading and antenna configurations in
real-world scenarios.
