Will CWNA be useful?

I have done Hardware & Networking and am thinking of doing CWNA please help by giving suggestions. Thank you.

Will it be useful? Yes it will be. But what's the main purpose of opting for CWNA?

@big_k:For certification and interest in wireless networking sir

Certification is just an official confirmation of the knowledge you have. I got bit confused by the title of the thread.

sorry, yes for knowledge and will it be useful also for making a good career?
