connectivity issue

Hi,

Using one of the free application , i can see client getting around -65dB Signal strength . 

if in case the noise level is very high for example -90 dB somethinng like that  , adding another ap in that area will be good or is just fine .

How can i check the noise level and SNR in aruba. 

 

Thanks

To check the signal level of the client, type "show ap association client-mac <mac address of client".

To check the noise, type "show ap debug radio-stats ap-name <name of ap> radio 0 | 1 advanced | include Noise"

 

-90 is not considered high.

Re: connectivity issue

SNR = S/N

SNR[dB] = S[dBm] - N[dBm]

 

-70dBm - -85dBm = 15dB
