Design of Low Power Wide Area-network via Small Flying Objects Constellation

Abstract

In case of a disaster happening, one of the critical problems is the lack of robust communication systems capabilities for the people under the disaster. This paper proposes the portable or reconfigurable wide area network with specified low-power radio station equipment via multiple small flying objects constellations to achieve the data relay communication system. The unmanned small flying vehicles, such as drones or multicopters with specified low-power radio transmitters provide responsiveness. The small satellite with high sensitivity receiver and high-speed transmitter achieves wide-area communication, and robustness for on-ground disasters. The system concept and design policies are evaluated by rough numerical studies with realistic hardware constraints. The results show the feasibility of the proposed concept with the specific case study.
