## 3 UAV 6G Networks
### 6G Application Requirements  
With the goal of making blockchain utility more understandable, in this study 6G applications are separated into two major groups. Ultra-reliability, low latency, increased data speeds and huge connection are among the typical criteria. I view of the pertinent factor in almost entire wireless communication generations, these needs are made part of the first category. These are referred as Qualification Group-I (QG-I). QG-I standards necessitate considerable improvement for potential 6G applications. The prime features for any reliable and secure network include non-reputability, confidentiality, defined level of secrecy, data integrity and auditability. These features are catered in second group named Qualification Group-II (QG-II). Based on the literature review and future application requirements, it is established that applications based on the 6G network in the future will be bandwidth hungry and will utilize abundant data originating from different sources, including all senses of human being, other devices. Said requirement will demand employment of requirements as divided in QG-I and QG-II. There is a lot of discussion in 6G vision papers about various technologies that can help with additional improvements in QG-I values. A few of the important 6G technologies include AI, Reconfigurable Intelligent Surface and THz communication [67]. We predict that improvements in these upcoming technologies and communication models will certainly facilitate 6G systems for the provision of high broadband capacity to even a bigger number of network nodes ensuring low latency and improved reliability. On the other hand, there is little mention of QG-II in the 6G literature. This is attributable to a number of factors. The scope and description of the security feature may change in connection with scenarios in different applications, on the basis of character of different units concerned that include machines, devices and controller. Hence, assigning responsibility for meeting these needs is therefore not straightforward. Fixing QG-II values will become more difficult as the complexity in requirements related to potential 6G applications increases. UAVs will be employed with prominent roles in futuristic 6G communication models due to their low cost and flexibility of deployment. In said, context, unmanned aerial vehicles (UAVs) have received a lot of press recently, both for military and commercialpurposes. 6G is designed to be an all-coverage network that can connect people in space, on the ground and underwater. UAVs can provide wireless coverage from the air in a variety of ways, such as Aerial base stations for users globally, relays to provide coverage to dispersed nodes and typical mobile network end users. Small UAVs have limited onboard power that results in limited capability of these devices for provision of temporary wireless communication. It becomes a significant problem to extend the lifetime of UAVs and produce green UAV communication with low power consumption. For future air transportation, 6G technology can make use of non-terrestrial networks (NTNs). \"Connectivity from the sky\" is one of the most groundbreaking 6G networking trends. In 6G communication, non-terrestrial network amalgamation is one the potential aspect. NTN provides aerial vehicle networking in air space for ensuring worldwide omni-present communication services [60]. Currently, TNs have limited capacity to ensure required connectivity as well as coverage to UAVs that are mobile with faster speeds. Consequently, Air-to-Air and Air-to-Ground are employed for commercial airlines and are not expected to serve networking facilities to future populated aerial vehicles. As a result, 6G is a suitable and enabling technology for UTM systems.
