Abstract Recently, Unmanned Aerial Vehicles (UAVs) are being utilized to ensure a better solution to a dependable and cost-effective wireless communication network from the sky. The adoption of UAVs has been considered as an alternative supplement of the existing cellular networks, to accomplish better transmission efficiency with enhanced coverage and network capacity. This article has represented some urban 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) after utilizing UAVs in the wireless network. This article might be informative to those who are engaged in research regarding UAV assisted wireless communication.

1 Introduction Meanwhile, the innovation of highly capable UAVs (Unmanned Aerial Vehicles) has likewise prompted a lot of enthusiasm for the utilization of UAVs to ensure reliable and financially savvy solutions for wireless communications in many practical world scenarios. Specifically, by the support of wireless communication devices, UAVs can be quickly implemented as floating BSs (base stations) in 3D (three-dimensional) space. The UAVs for wireless communication have been viewed as a promising method to give universal access from the sky towards the ground UEs (user equipment) in specified regions for permanent support or temporary network support (e.g., hotspot zones). Contrasted with the ground static BSs, one unparalleled bit of leeway of utilizing UAV-based flying BSs is that their positions and heights can be progressively changed to provide on-the-fly U2G (UAV-to-Ground) wireless communication links. The deployment of flying BSs has been regarded as an effective * Mobasshir Mahbub [email protected] 1

supplement of existing cellular frameworks to improve wireless network capacity and coverage expansion on the ground with higher traffic demands, to cope with the prerequisites of the 5G (fifth generation) and beyond cellular communications [1]. As an outcome of down to earth demands, few UAV assisted wireless communication networks from different industrial communities have just been initiated, for example, AT&T’s all-weather flying Cell on Wings (COW) to give the LTE (Long Term Evolution) coverage of the 4G (fourth-gen) cellular networks, Verizon’s ALO (Airborne LTE Operations) to empower access to remote connectivity, N
