The practical applications of UAVs in healthcare, surveillance, agriculture and other domains is increasing at a faster pace. Mass production of these UAVs is essential to meet the growing communication requirements. Plans towards standardization and global deployment of Internet- of-Things (IoT) technologies and fifth generation (5G) wireless communication are in progress. Functional diversity is established by the UAVs in enabling wireless communication with IoT and 5G technologies. The different UAVs used in wireless communication is studied and a hierarchical architecture is proposed to facilitate integrating these technologies into next-generation networks. The principles of aerodynamics, wireless communication, power transfer, area of coverage, delay, meteorological impacts and other design parameters and their tradeoffs is analyzed.

Introduction Entertainment industry, emergency rescue, security surveillance, agricultural practice, scientific research, industrial inspection, civilian applications, military exploration and various such fields are making use of the benefits of unmanned aerial vehicles (UAVs) leading to a rapid transformation in the domain [1]. Meanwhile, the rapid deployment of Internet of- Things (IoT) and fifth generation (5G) wireless network technologies further enrich the applications and accelerate the diversity and progress of the paradigms. International Telecommunication Union (ITU) speculated application scenarios can be facilitated with the 5G wireless technology aided by UAVs. Massive machine type communications (MMTC), ultra-reliable low latency communications (URLLC), and enhanced mobile broadband (EMBB) are the three principle application scenarios. URLLC is used for handling emergency situations like enhancement of public safety networks, recovery of network service in areas stricken by disaster and so on where UAVs can be deployed to offer efficient outcomes [2]. The network performance can be improved in 5G cellular network up-to thousand times when compared to that of 4G network using UAV based EMBB. Cellular services make use of millimeter wave (mmWave) bands while adopting Upper Microwave Flexible Use Service according to the Federal Communication Committee (FCC) since 2016 [3]. Significant challenges in terms of shadowing effects, huge propagation loss in terrestrial environments are faced by mmWave cellular communication at faster speed and larger bandwidth opportunities. Beamforming schemes can be used despite the high power consumption and hardware resources for overcoming the challenges of propagation loss [4]. In non-line-of-sight (NLoS), the shadowing variance is high and mitigation of mmWave is difficult due to the shadowing effects. The limited channel elements and sparse nature of mmWave channels can be overcome by improving the line-of sight (LoS) communication by deploying wireless networks with UAV technology. Reliable and robust 5G global access is enabled with distinct Earth-space communication with the help of UAV based satellite communication in the near future [5].
