    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.

    Hi,

    Thank you for the reply . 

    if the signal strength is -70 dBm and noise is -85dBm

    How do we calcualte SNR 

    Thanks again

    SNR = S/N

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

     

    -70dBm - -85dBm = 15dB
