High noise in Mesh system

[Mitch23]

Hi Everyone,

So we've just installed a new outdoor mesh system with WLC 9800 and APs 9124AXE.

See the layout below.

After configuration we are experiencing huge noise (in DNA the APs health is 1) both in case of 2.4 and 5 GHz spectrum.

Besides it the wireless network signal leves is not as good as we expect (not a huge are what must be covered).

Some settings:

- tri band and dual radio modes are disabled

- backhaul is 5GHz (manual channel & 40mhz width)

- client access on backhaul is enabled

- mesh, rf, ap join and the other necessary profiles were set

- preferred parents were set and the tree is good

- tried low and high output powers too

I've tried several channels and some other settings but idk why is the issue still exist...

Please help me!

Thank you in advance!

 Why do you have this desing? Sorry for asking. You may want help on the design you have but, sometimes the problem is the design.

Mesh network should be for specific requirement. For example, you want to connect two dots using wifi because you are unable to run cables.

If you need to cover all the area, your APs is pretty much in bad position. You are covering pretty much well your walls and the middle  of the warehouse is in the dark.

Noise is something coming from outside mostly. If you are really being affected by noise, you need to understand the source.

Noise will be always around but what really matters is the SNR. If you have an excellent RSSI, the noise is not the end of the world.
