May I know is CWTS compulsory before going for CWNA ?I am preparing for the CWNA from Sybex guide PWO-105.
No, it's not.
CWTS is a great stepping stone for people completely new to Wi-Fi. It is also aimed at sales professionals, help desk support technicians and so on. However, it is in no way required to become a CWNA.
Frames Are Food,
It's a great place to start. I was suprised on the content of the CWTS.
