====== Ubiquiti - WiFi - Channel Width ======

Channel Width sets the width for each frequency band of the Wi-Fi radios.

  * 20 MHz is the base channel width, but multiple channels may be bonded together to increase data rates and throughput.

===== Recommendation =====

  * **2.4 GHz**:  Always set to 20 MHz.
    * There is not enough space in the 2.4 GHz spectrum to reliably use 40 MHz channels, especially with multiple APs. 

  * **5 GHz**:  Set to 20, 40, 80, or 160 MHz.
    * A higher setting value will provide a higher throughput. 
      * Some clients may not fully support 160 MHz channels in 5 GHz, which requires DFS (Dynamic frequency selection).
    * A lower setting value will support higher client density.

  * **6 GHz**:  Set to 80 or 160 MHz.
    * There is a lot of available spectrum for wide channels, and no requirement for DFS (Dynamic frequency selection) or AFC (Automated Frequency Coordination).
