In accordance with an embodiment, a first electronic device is configured to communicate with a first ultra-wideband base station via ultra-wideband wireless communication and receive coordinates of the first electronic device that are based on a relative location between the first electronic device and the first ultra-wideband base station. The first electronic device is further configured to display a control window of a second electronic device in response to detecting that the first electronic device is located in a front area of the second electronic device and points to the second electronic device.

First electronic device and method for displaying control window of second electronic device

A variable capacitor-based antenna adjustment method and a related apparatus. A first signal strength of a first communications system with a highest priority that is supported by an antenna having a variable capacitor is detected, and when the first signal strength is relatively strong to meet a first release condition, a capacitance value of the variable capacitor is adjusted to a preset capacitance value, where the preset capacitance value is closer to a second capacitance value corresponding to a working frequency band of a second communications system supported by the antenna, so that a working frequency band of the antenna having the variable capacitor is closer to the working frequency band of the second communications system, and therefore, communication quality of the second communications system is improved.
