Unmanned aerial vehicles (UAVs) have been applied to various promising applications
because of their features of high‐mobility, portability, rapid deployment, and modest power …

In most countries, small (< 2 kg) and medium (< 25 kg) size unmanned aerial vehicles
(UAVs) must fly at low altitude, below 120 m, and with permanent radio communications with …

In the design of unmanned aerial vehicle (UAV) wireless communications, a better
understanding of propagation characteristics and an accurate channel model are required …

Small‐and medium‐sized unmanned aerial vehicles (UAVs) can fly for a short distance (< 2
km) from a control station in a nonsegregated air space (altitudes< 100 m). It is of great …

This article studies the air-to-ground ultra-wideband channel through propagation
measurements between 3.1 to 4.8 GHz using unmanned-aerial-vehicles (UAVs). Different …

A new analytical model of air‐to‐ground (A2G) channel between a low altitude unmanned
aerial vehicle (UAV) and a mobile station is derived. It is proposed for the dense urban …

The use of unmanned aircraft systems (UAS) for the fifth generation (5G) and beyond 5G
(B5G) mobile communications has aroused great attention in decade years. Regardless of …

In recent years, unmanned aerial vehicle (UAV)-to-ground wireless channels have become
focused areas. Thus a better understanding of UAV-to-ground wireless channel …

Air-to-ground (A2G) communication is a fundamental technology for integration of
