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.

Success Stories

I literally just came out of the testing centre having taken the CWDP exam. The certification process opened my mind to different techniques and solutions. This knowledge can only broaden your perspective. Great job, CWNP, you have a great thing going on here.

Working through the CWNP coursework and certifications helped not only to deepen my technical knowledge and understanding, but also it boosted my confidence. The hard work it took to earn my CWNE has been rewarding in so many ways.

I want to commend you and all at CWNP for having a great organization. You really 'raise the bar' on knowing Wi-Fi well. I have learned a ton of information that is helping my job experience and personal career goals, because of my CWAP/CWDP/CWSP studies. Kudos to all at CWNP.
