    摘要: Systems and methods configured to form and point beams from an unmanned aerial vehicle (UAV) toward target cells in a coverage area on the ground. One embodiment determines and forms the required number of UAV fixed beams needed to cover the target area when UAV is at its highest altitude and highest roll/pitch/yaw angles so that the target coverage area is covered under ail UAV altitude and orientation conditions. In another embodiment, UAV determines the beam pointing angles toward different cells on the ground using information on position coordinates and orientation angles of the UAV, and the position coordinates of the cells in the coverage area relative to the center of coverage area. In another embodiment, a reference terminal placed at the center of coverage is used by the UAV to optimally point a beam toward center of the coverage area.

    摘要: A communication system is described. The system includes: at least one gateway able to provide broadband connectivity, a set of ground terminals, and a set of aerial platforms, where at least one aerial platform is able to communicate with at least one gateway using radio frequencies, each aerial platform is able to communicate with ground terminals using radio frequencies, and each aerial platform is able to communicate with each other aerial platform using radio frequencies. An automated method for determining a beam direction for communication among UAVs includes: dividing a space around the UAV into multiple sub-regions, and, iteratively: selecting a sub-region from among the multiple sub-regions; pointing a signal toward the sub-region; and determining whether a signal is received from another UAV, until all sub-regions from among the multiple sub-regions have been selected.

    摘要: Systems and methods for mitigating the effects of atmospheric conditions such as rain, fog, cloud in a broadband access system using drone/UAVs. In one embodiment, terminal and drone radio and transmission medium fixture sub-systems comprise multiple transmission media. In one embodiment, in response to changes in atmospheric conditions the drone radio sub-system switches transmission medium to reduce the effects of atmospheric conditions. In another embodiment, the terminal and drone radio sub-systems equalize the data rates among terminals in response to changes in atmospheric conditions observed by different terminals. In another embodiment, the drone radio sub-system adjusts the transmit power on the downlink to different terminal according to fading due to atmospheric conditions on each link.
