There is a simple way to perform any RF math calculation without having to use logarithms and mathematical formulas. This method is known as the 3s and 10s Rule (or sometimes the 10s and 3s Rule). If you remind five basic steps you can perform any RF math calculations. The five basic steps are as follows:
* 0 dBm = 1 mW (starting point)
* Increase by 3 dBm and power in mW doubles or x 2
* Decrease by 3 dBm and power in mW is cut in half or /2
* Increase by 10 dBm and power in mW is multiplied by 10 or x 10
* Decrease by 10 dBm and power in mW is divided by 10 or /10
I was towards the end of my CWNA studies when I discovered on CWNP's website that the CTWS (PW0-071) entry-level exam is a lifetime certificate unlike the CWNA (CWNA-106) which is valid for only 3 years. The thought of having a lifetime cert is so tempting that I booked for CWTS exam instead and will take CWNA early next year. You'll need to go to Pearson VUE's website to register and schedule for a CWNP exam. Once registered, your login will be sent to your email within 24 hours.
The login for the CWNP website is different from the login used in Pearson VUE (to book for CWNP exam). To Create a new login go to the CWNP website > Member Login > Create a CWNP Account.
CWNP doesn't ship a hard copy cert so you'll need to download and print it yourself. Here's how the CWTS look like. The cool thing about this cert is that it's LIFETIME.
