     {IDF_TARGET_NAME} 支持 Wi-Fi 带宽 HT20 或 HT40，不支持 HT20/40 共存，调用函数 :cpp:func:`esp_wifi_set_bandwidth()` 可改变 station/AP 的默认带宽。{IDF_TARGET_NAME} station 和 AP 的默认带宽为 HT40。
 
     station 模式下，实际带宽首先在 Wi-Fi 连接时协商。只有当 station 和所连 AP 都支持 HT40 时，带宽才为 HT40，否则为 HT20。如果所连的 AP 的带宽发生变化，则在不断开 Wi-Fi 连接的情况下再次协商实际带宽。

     理论上，HT40 可以获得更大的吞吐量，因为 HT40 的最大原始 PHY 数据速率为 150 Mbps，而 HT20 为 72 Mbps。但是，如果设备在某些特殊环境中使用，例如，{IDF_TARGET_NAME} 周围其他 Wi-Fi 设备过多，HT40 的性能可能会降低。因此，如果应用程序需要支持相同或类似的情况，建议始终将带宽配置为 HT20。
