Thread: Noise floor

  1. #1

    Default Noise floor

    Is -100 dBm the default value for noise floor when calculating for SNR?

  2. #2



    The -100 dBm you see in Chanalyzer and what a client will use as a noise floor are different.

    Stations can only detect and use 802.11 traffic to determine the noise floor.

    Once they find the noise floor it's just subtracting the RSSI and noise floor. It's not an actual ratio.

  3. Default

    Where can I get an actual ratio?

  4. Default

    So, guys, any update on this?
