This paper presents a comprehensive theoretical framework for the use of radiocommunications Unmanned Aerial Vehicles, summarizing fundamental concepts and operational relationships. By conducting a systematic literature review, we evaluated the challenges and opportunities associated with UAV communications, focusing on their role in military operations. Employing a Systematic Literature Review (SLR) methodology aligned with PRISMA guidelines, important research was collected. Our analysis shows the pivotal role of UAV communications in establishing information superiority, facilitating decision-making, and augmenting operational efficiency. However, persistent challenges such as communication range constraints, security vulnerabilities, and the need for standardization are identified. In conclusion, this research contributes to show the particulars of UAV communications and lays a foundation for subsequent studies in this domain. This paper advocates for continuous exploration of the relevance within the dynamic domain of UAV technology.
