ExtremeWireless Auto Channel selection

[Andre_Brits_Kan]

Hi Community

So I have a question for the community and would like to get your comments on the topic.
I have been deploying the solution for years now (From when Enterasys started with the product).

When I do the initial configuration of the controller, I usually configure the AP's default settings to Auto select the Channel for both 2.4Ghz and 5Ghz.

With the various code releases "Dynamic Channel Selection" was introduced, some version setting this to Monitor only and other version setting this to Active Mode by default.

The question I have is that at most of the deployments across the years I have seen that the AP's would all place their channels on both the 2.4Ghz and 5Ghz on the same channel.

I usually end up with statically assigning Channels to avoid the same channel selection.
I understand that I might have outside interference cause all the AP's to try and hog the same channel.... But I have seen other systems deployed in the same space and the channel selection was perfect, every AP on it own unique channel.

What have you experienced on this, lets discuss your experience regarding this matter and your recommendations.

Regards

Andre - it would be interesting to understand how long you waited between powering up the AP's and determining that all are on the same channel. If you look shortly after initial power-up you will find many adjacent AP's on the same channel (2.4GHz more likely, given the fewer number of channels).

The DCS algorithm takes some time - during an initial deployment - to level out and determine all of the correct channels for operation. Depending on the size and density of deployment this may take longer.

Hello, Andre!

I think it's depends on phisical topology, numbers of AP's, numbers of clients, functional which work at AP's...

DCS - it's good functional, but if there is a lot of AP's, clients then AP's have to have some time to relocate to other channels and it's can be critical for applications.
So in this case, in my mind, you have to configure statical channel plan.

If you have not so many AP's, not so many clients, a lot of interferences, so it's better to enable DCS.

Thank you!
