    Hi there,

    I am preparing for CWNA Exam and i have bought Official CWNA book. While going through the RF Math chapter I am bit confused about dB and dBm.
    In an example book says +3dB means multiplication with 2. In another example book says +3dBm has been taken as *3 as in +10dBm +3dBm equals to 30dBm.

    Can anyone clarify please.

    Regards,
    Opinder.
