UAV Assisted 5G Het-Net: A Highly Supportive Technology for 5G NR Network Enhancement

Abstract

Recently, unmanned aerial vehicles (UAVs) have grabbed impressive attention from industry and research network, because of the faster growth in a wide scope of applications. Especially, UAVs are being utilized to ensure a better solution to a dependable and costeffective wireless communication network from the sky. The adoption of UAVs has been considered as an alternative supplement of existing cellular networks, to accomplish better transmission efficiency with enhanced coverage and network capacity. This article has represented some wireless communication scenarios where UAVs can be utilized to ensure better coverage, enhancement of efficiency and capacity. After that, to establish the effectiveness of UAVs in wireless communication the paper has included several performance scenarios (path loss, attenuation, and data rate) after utilizing UAVs in the wireless network. Finally concluded with discussing several challenges for UAV assisted wireless networks and the scopes of further enhancement of such kind of networks. This article might be informative to those who are engaged in research regarding UAV assisted wireless communication.

Joint User-Slice Pairing and Association Framework Based on H-NOMA in RAN Slicing

“…Second, we can combine HetNets with aerially controlled networks such as Unmanned Aerial Vehicles (UAVs) are required to overcome these challenges. UAV-aided HetNet shows lower transmission delay (lower latency) and better average jitter compared to without UAV-based HetNet, because UAVs control the transmission of packets with efficient utilization of available bandwidth from source to destination [ 62 ]. Third, we can use FANETs [ 63 ], in which multiple UAVs cooperate and establish an ad hoc network in a multi-UAV scenario to enhance network performance.…”

Drone Swarms as Networked Control Systems by Integration of Networking and Computing

“…Free-space fading phenomenon is reliant on LOS conditions as well as earth surface reflecting effects to decrease transmission strength as the waves propagate through free space [ 47 ]. Attenuation on the other hand, occurs due to loss in the radio signal transmission strength as it traverses in the frequency band [ 48 ]. The dominant cause of attenuation in air-to-air and air-to-ground transmissions come from atmospheric conditions of rain and gases.…”

“…Additionally, the authors mentioned that the frequency bands used for drone communication (c.f., 2.4 GHz, 3.4 GHz, and 5.8 GHz), are severely influenced by the environmental conditions mentioned including buildings, trees and distance between transmitter and receiver antennas to impact on the drone control systems ability to provide the needed coordination movement of the swarm. Meanwhile, thoughts of use of higher frequency carriers for drone propagation may result in high signal attenuation, leading to higher packet losses, as higher frequency bands have lower penetrating capabilities into obstacles when compared to low frequency carriers [ 48 ].…”
