    Hi,

     

    I don't have any formal training in RF engineering or even wifi for that matter, so forgive me if this is a silly question.  

     

    I am querying my IAP225 cluster's noise floor through SNMP (.1.3.6.1.4.1.14823.2.3.3.1.2.2.1.6, aiRadioNoiseFloor)  , and all my APs are returning values of 97.  There is no negative sign, but I am assuming this means (-)97 dBm?  I am in the middle of a busy, metropolitan environment.  Could this really possibly be +97 dBm?

    Now I'm also wondering whether I need to turn the spectrum monitor on to even get an accurate reading for this property...
