Abstract:
A solar powered aircraft having segmented wings that can be reconfigured during flight to optimize collection of solar energy are described. The aircraft have rigid construction that is resistant to inclement weather and is configured to rely on free flight control at high altitude and under conventional conditions, thereby providing flight duration in excess of 2 months. The aircraft is particularly suitable for use as part of a telecommunications network. A telecommunications network incorporating such aircraft is also discussed.
Abstract:
An Unmanned Aerial Vehicle (UAV) comprises a situational awareness system coupled to at least one onboard sensor and senses the location of other UAVs. A cooperative Radio Access Network (RAN)-signal processor is configured to process RAN signals cooperatively with at least one other UAV to increase the rank of the RAN channel and produce RAN performance criteria. A flight controller provides autonomous navigation control of the UAV's flight based on the relative spatial locations of other UAVs and the RAN performance criteria, which operates within predetermined boundaries of navigation criteria. The UAV can employ mitigation tactics against one or more UEs identified as a threat and may coordinate other UAVs to conduct such mitigations.
Abstract:
According to some embodiments, an unmanned vehicle includes a power supply configured to supply an electrical power signal to a motor for propelling the unmanned vehicle, a wireless communication device configured to transmit or receive a radio frequency (RF) signal, and a motor feed antenna coupled to the power supply and the wireless communication device, the motor feed antenna configured to conduct the electrical power signal from the power supply to the motor, and to transmit or receive RF signals as an antenna for the wireless communication device.
Abstract:
The present document relates to a method for providing mobile telecommunication services to user equipments (120) using a drone base station (140), the drone base station (140) comprising base station equipment mounted on a drone. The method comprises the steps of: - executing a recording procedure by moving the drone base station (140) in an area around an initial geographic position and gathering information regarding radio link conditions between candidate user equipments (120) and the drone base station (140) and regarding radio link conditions between the drone base station (120) and a backhaul node (150) serving the drone base station (140); - performing a position adjustment procedure for adjusting the position of the drone base station (140) based said gathered information, the position adjustment procedure providing an adjusted geographic position; - controlling the drone base station (140) to move to the adjusted geographic position; and - operating the base station equipment at the adjusted geographic position.
Abstract:
The systems and methods are provided to provide communication coverage to an unmanned aerial vehicle. A proposed flight path of a UAV may be collected, and a communication signal distribution, such as a cellular signal distribution, along the proposed flight of the UAV may be determined. At positions having low or no communication signal, relays may be provided to improve a quality of the communication signal. The relay may be a ground device or an aerial vehicle. A stable and continuous communication between the UAV and user terminals during the entire flight path of UAV may be provided, and a coverage of cellular signal may be expanded.
Abstract:
A device, and method, for situational awareness of an emergency scene for first responders uses an unmanned aerial vehicle equipped with a sensor package in populated or otherwise restricted areas. The unmanned aerial vehicle is assigned to a control center for a designated incident while automatically tasking the unmanned aerial vehicle with the initiation of the incident response to autonomously proceed to the incident prior the control center taking active control of the unmanned aerial vehicle.
Abstract:
A method and apparatus for use in an ad hoc network, comprising: a node transmitting an extended allowable hold time value to a further node; the node changing its transmission behavior such that the further node stops receiving transmission from the node for an extended period, for example by pausing transmission at least in the direction of the further node; and the further node treating the link to the node as intact during the extended allowable hold time. The transmitting of the extended allowable hold time value may be performed earlier than a next routine transmission of routine allowable hold time value would have been sent. The method may further comprise the node being instructed to maintain topology information for an extended time.
