    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: 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.
