Abstract: Described herein are technologies for intelligent antenna selection for optimal performance in an electronic device. One electronic device includes a first radio, coupled to a first antenna and a second antenna, and a processing device coupled to the first radio. During a first period, the first radio transmits a sequence of data packets using the first antenna and the processing device receives a first metric value indicative of a first amount of power received on a third antenna of the second electronic device. During a second period, the first radio transmits the sequence using the second antenna and the processing device receives a second metric value indicative of a second mount of power received on the third antenna. The processing device selects one of the first antenna and the second antenna as a selected antenna based on which one of the first metric value and the second metric value is lower. The processing device causes the first radio to communicate data with a third device using the selected antenna.

Abstract: A plurality of UAVs may be operated in a fleet, each of the UAVs in the fleet being configured to work collectively to achieve one or more functions, such as to create a display or implement an antenna array. The fleet of UAVs may operate individually and/or may be coupled to one another to operate as a collective unit. In some embodiments, one or more UAVs in the fleet may operate individually, while two or more UAVs in the fleet may be connected to one another. In such embodiments, the individual UAVs and the connected UAVs may together comprise the fleet.

Abstract: This disclosure describes a power unmanned aerial vehicle (UAV) that may generate a current from a conductor of an overhead power line carrying an AC power signal. The power UAV has a receptor that includes a secondary coil. Current is generated by the secondary coil of the receptor from magnetic fields emanating from the overhead power lines while the power UAV is flying. The generated current may be used to fly the power UAV, recharge an energy storage device of the power UAV, or be provided to another UAV. In various implementations, while the power UAV is flying, the power UAV may receive another UAV, recharge the other UAV, and then release the UAV to resume flying. In various implementations, the power UAV may also monitor characteristics of the power delivery system.

Abstract: A user device selects a communication module from a plurality of communication modules of the user device to communicate first data to a first device in a first configuration, selects a first antenna from a plurality of antennas of the user device to communicate the first data in the first configuration, and couples the communication module to the first antenna in the first configuration. The user device additionally selects the communication module to communicate second data to a second device in a second configuration, selects the first antenna and a second antenna from the plurality of antennas to communicate the second data in the second configuration, and couples the communication module to the first antenna and the second antenna in the second configuration.
