Correlation between Channel Width and DBS

2023-04-17 18 58 00.png

I don't know the correlation between Channel Width and DBS.

To use best channel bonding
Set Channel Width to BEST
Should I set DBS to Max Allowed?

As above, if DBS is 40Mhz,
Is 80Mhz bonding dynamically disabled?

DBS only works when the channel width is set to BEST.

- Channel width and DBS (Dynamic Bandwidth Selection) are both related to the amount of available bandwidth for Wi-Fi transmission.
      Channel width refers to the amount of frequency spectrum used for transmitting data in a single channel. In general, wider channel widths allow for higher data rates but also increase the likelihood of interference and congestion.
     DBS is a feature that allows Wi-Fi devices to automatically adjust their channel width based on the available spectrum in the environment. This means that devices will use a narrower channel width when there is congestion or interference and a wider channel width when there is more available spectrum.
     To use the best channel bonding, setting the channel width to "BEST" is a good option as it allows the devices to automatically select the appropriate channel width based on the available spectrum.
In terms of setting DBS to "Max Allowed," this may not always be the best option. DBS is designed to automatically adjust the channel width based on the available spectrum, so setting it to "Max Allowed" may result in unnecessary interference and congestion.
     Regarding your question about whether 80MHz bonding is dynamically disabled if DBS is set to 40MHz, it depends on the specific Wi-Fi device and its capabilities. Some devices may automatically disable 80MHz bonding if DBS is set to 40MHz, while others may still allow it. It is recommended to refer to the device's documentation or contact the manufacturer for more information.

    When the mirror will then always repond to me with ' The only thing that exceeds your brilliance is your beauty! '

For example, what will be the result when:
Channel width: 40Mhz (no best)
DBS: 80Mhz

DBS only works when the channel width is set to BEST.
