摘　　要：主要介绍FCC认证中5 GHz Wi-Fi设备的动态频率选择(DFS)测试要求,以不带雷达监控功能设备为例来讨论DFS的测试要求。通过介绍雷达波形、信道移动时间和信道停止传输时间、信道非占用时间等项目来判定EUT是否通过DFS的测试要求,并对测试项目具体操作规范及判定依据作出具体说明。The basic requirements of 5 GHz Wi-Fi DFS test in FCC certification are introduced. A slave device without radar detection function is discussed as a specific example for DFS test requirements. The necessary test items such as radar waveform, the time for channel moving, and transmission stopping, the time of channel available are introduced, which are used to decide if the EUT could meet the requirements of DFS test. The specific test procedures and decision evidence are involved in detail as well.
