“…A unique advantage of drone-hosted base stations is that they possess the ability to alter their position and location to address migrating crowds, changing environments, and other service-limiting parameters. Such networks are expected to support several appropriate scenarios, including raising the quality of cellular coverage in rural areas [1], assisting first responders in various accident situations or disaster zones [2]- [4], facilitating rescue and relief operations [5], and supporting connectivity during cellular network overloads or power failure events [6]. These works serve to highlight the potential applications and impact such technology usage may have across a number of sectors.…”

This paper presents a study which evaluated the potential for using ultra-low altitude, unmanned aerial vehicles to deliver fifth-generation (5G) cellular connectivity, particularly into areas requiring short-term enhancement in coverage. Such short-term enhancement requirements may include large gatherings of people or during disaster scenarios where there may be service outages or a need for increased bandwidth. An evaluation of this approach was conducted with empirically generated results regarding signal quality and cellular coverage-illustrating the potential of using unmanned ultra-low altitude aerial vehicles to deliver 5G cellular mobile services. Specifically, channel gain, mean time delay of the received signals (τ mean), and the root-mean-square spread of the delay (τ rms) were investigated for two distinct user modes at three different drone heights for three selected environments-an open area (field), a tree-lined environment, and an enclosed area. Maximum likelihood estimates for the various drone heights, user modes, and operational environments were found to be Rician distributed for the received signal strength measurements, whereas τ mean and τ rms for the open and tree-lined environments were Weibull distributed with the enclosed area tests being lognormally distributed. The paper also investigates how the channel gain may be affected when operating in each of the various global bands allocated for mid-5G communications, namely, Europe, China, Japan, South Korea, and North America. These regional mid-5G band allocations were found to yield minimal variance for all the environments considered.
