SNR Value

Hello all,

Is the SNR value monitored from Meraki's AP perspective or does the client somehow reports that to the AP?

I believe the AP reports the SNR value from between the AP and the client (so from the AP's perspective)

Its an active tool and changes in real time as meraki sees the client moving around. Check out this cool picture! 😄

Thank you. I have read this document: https://documentation.meraki.com/MR/Wi-Fi_Basics_and_Best_Practices/Signal-to-Noise_Ratio_(SNR)_and_...

but I was wondering if
- This is what the Meraki receiver measures, or
- What the Endpoint (Client) reports to the Meraki (not sure if that is even possible 😅)

Also yes I agree that value is not the actual received signal, but the SNR 😀that constantly changes.

Not completely related, but if you enable 802.11w (management frame protection) some clients (such as Intel NICs with up-to-date drivers) can report additional information (that appears in the dashboard) from the client's perspective.

on the client go to my.meraki.com

 

It will show the signal info to the AP you are connected to

The SNR value is the value of the most recent upstream frames from the client.  So the AP just shows how it actually receives the client frames.

So yes it is from the perspective of the AP.
Usually a value above 25 dB is considerd within spec.
