Reusing Channel to Control RX Sensitivity Tuning is incompatible with NonWiFi Interference(level3-5)

  • 1.  Reusing Channel to Control RX Sensitivity Tuning is incompatible with NonWiFi Interference(level3-5)

    Hi,

       I got confused on the relationship between Rx sensitivity and Non-WIfi immunity? please help me.

    1) why "Reusing Channels to Control RX Sensitivity Tuning" is not compatible with Non-WIFI Interference(level 3-5) on Non-11n APs?

    it just confuses me much. how to understand that?

     

    2) what's the relationship between the above 2 features? when a weak signal/noise comes to receiver, which feature would work first?

     

    Thanks,

    Will

    You must have read the article here:  http://community.arubanetworks.com/t5/Controller-Based-WLANs/What-is-channel-re-use-and-how-does-it-help-improve-WLAN/ta-p/177376

     

    1.  It is not compatible, because they conflict.  "Channel Reuse" when static changes the receive sensitivity based on the power of the AP.  Dynamic changes the receive sensitivity based on channel load.  Interference Immunity does change the receive sensitivity but it is just a number that is not based on AP power or channel load; it is not compatible with channel reuse..

    2.  I don't know what takes precedence when both options are enabled, but very, very few people use either options.
