  • Publication number: 20210167848
    Abstract: A horizontal distance of an unmanned aerial vehicle (UAV) relative to a remote control device and a height of the UAV relative to the remote control device are obtained. A remote control distance is calculated based on the horizontal distance and the height. It is determined whether the remote control distance increases or decreases. At least one of a first signal transmission power of the UAV or a second signal transmission power of the remote control device is controlled according to a result of the determination. The at least one of the first signal transmission power or the second signal transmission power is increased or maintained in response to determining that the remote control distance increases. The at least one of the first signal transmission power or the second signal transmission power is decreased or maintained in response to determining that the remote control distance decreases.
