Rotational Flying Station for Wireless Access in Large Disaster Area.

In disaster-affected areas, the lack of cellular network connectivity can be a matter of life and death. To address this issue, we propose the use of an unmanned aerial vehicle (UAV) equipped with a small base station that can provide emergency networks. However, existing research shows that the coverage range of such UAVs is limited and can be costly. To overcome these challenges, we introduce an innovative Rotational Flying communication drone that features a UAV with a rotational antenna attached to a cellular base station. Our solution expands coverage, saves power, and reduces costs, enabling victims to contact rescue teams and address their situation. With our technology, users can communicate in real-time through video, share aerial footage of affected regions, and engage in asynchronous text chat even when cellular or wireless networks are down. We conducted a thorough analysis of the flying communication server’s range of connections, including the user ground-covered distance frequency rate to disperse the network. Our simulation results with a theoretical explanation that validates that coverage expansion, power savings, and low costs can significantly improve emergency communication and provide a network with fewer drones than the existing work.
