Dynamic frequency selection method and related device

A communication apparatus includes a first device, a second device, and a control circuit. A first device is configured to establish a wireless link with a wireless communication device in a first communication channel. The second device is configured to perform a first scan for a predetermined duration on the second communication channel to detect whether there are any radar signals on the second communication channel. In response to the first scan satisfying a predetermined condition, the control circuitry controls the first device to move the wireless link from the first communication channel to the second communication channel. Using the method, the wireless link may be moved to the second communication channel. 提供一种通信装置，包括第一设备、第二设备以及控制电路。第一设备用于在第一通信信道中与无线通信设备建立无线链路。第二设备用于对第二通信信道执行预定时长的第一扫描以检测第二通信信道上是否有任何雷达信号。响应于第一扫描满足预定条件，控制电路控制第一设备将无线链路从第一通信信道移动到第二通信信道。使用该方法，可以将无线链路移动到第二通信信道。
