| In this article, the influence of various factors and conditions of data transmission on the energy reserve of radio communication channels with small-sized unmanned aerial vehicles performing flight tasks within the "smart cities" with dense buildings is evaluated using mathematical modeling. It is shown that modern cities of this type, due to the presence of buildings of various heights with various reflection coefficients and a significant level of electromagnetic interference, create specific conditions for the propagation of radio waves, forming multipath fields with a complex interference structure and sharp spatial changes in signal levels, which creates a number of issues related to both the quality of communication and its reliability, including, in particular, the determination of energy reserves of radio communication channels. For their quantitative evaluation, mathematical models, typical data transmission parameters and energy characteristics of both unmanned aerial vehicles and ground-based control systems were selected. On their basis, a corresponding study of the energy reserve of the radio communication channel was conducted, and the corresponding conclusions were drawn based on the results of modeling. | ||
