Abstract: Systems and methods are provided for a network of relay drones utilized as a set of relays or linkages between a base station and a working drone controlled by the base station. The relay drones in the network may augment a communication link or communication signal between the base station and working drone. Relay drones may augment the communication link by acting as nodes that relay communication between the base station and the working drone by boosting the communication signal at each node to compensate for loss of signal power over a traveled distance and/or providing a path with a direct line of sight between the base station and working drone. Directional antennas may be utilized when a direct line of sight is established, which may improve communication signal efficacy when compared with omnidirectional antennas.

Abstract: A plurality of mobile robots provide a radio coverage area of a wireless communication network. Each mobile robot comprises a radio base station of the wireless communication network. A mobile robot of the plurality of mobile robots moves to a geographical position to deploy as part of a daisy chain loop of the mobile robots upon receiving instruction from a maintenance base. Upon receiving further instruction from the maintenance base, the mobile robot moves to a further geographical position as part of a circular shift operation performed by the mobile robots deployed to the daisy chain loop to maintain the radio coverage area and send a further mobile robot of the mobile robots deployed to the daisy chain loop to the maintenance base.

Abstract: Systems and methods are described for an automatically deployed wireless network. According to one embodiment, an access point controller (AC) determines the existence of a network anomaly at a position of a wireless network that is managed by the AC. Responsive thereto, the AC causes an unmanned vehicle that carries a movable access point (AP) to carry the movable AP to the position or proximate thereto and causes the movable AP to provide wireless network service to an area encompassing the position by sending a dispatch command to the unmanned vehicle. The dispatch command instructs the unmanned vehicle to move to the position or proximate thereto.

Abstract: The drone-based radio-over-fiber system provides an unmanned aerial vehicle (AV), preferably a multi-rotor drone, connected to a base station by a tether including an optical fiber. A radio frequency-over-fiber system is used for bidirectional data communications between at least one radio frequency (RF) transmitter at the base station and at least one antenna mounted on the drone through the optical fiber in the tether. The system includes wave division multiplexers/demultiplexers that permit ultrahigh bandwidth communication over the tether. An embodiment of the system for 2×2 multiple-input, multiple-output (MIMO) signals in the 700 MHz LTE band is described.

Abstract: A span-loaded, highly flexible flying wing, having horizontal control surfaces mounted aft of the wing on extended beams to form local pitch-control devices. Each of five spanwise wing segments of the wing has one or more motors and photovoltaic arrays, and produces its own lift independent of the other wing segments, to minimize inter-segment loads. Wing dihedral is controlled by separately controlling the local pitch-control devices consisting of a control surface on a boom, such that inboard and outboard wing segment pitch changes relative to each other, and thus relative inboard and outboard lift is varied.

Abstract: Drone-based wireless communications systems are provided, as are methods carried-out by such wireless communications systems. In one embodiment, the wireless communications system includes a Satellite Signal Transformation (SST) unit and a plurality of aerial network drones, which can be deployed over a designated geographical area to form a multi-drone network thereover. During operation, the SST unit transmits a network source signal, which contains content extracted from a satellite signal. The multi-drone network receives the network source signal, disseminates drone relay signals containing the content through the multi-drone network, and broadcastings user device signals containing the content over the designated geographical area. In embodiments, the multi-drone network may broadcast multiple different types of user device signals for reception by various different types of user devices located within the designated geographical area, such as an area containing communication infrastructure disabled by a natural disaster, a hostile attack, or other catastrophic event.
