CWNA - 802.11 j,v,w,y,z,aa

Do I need to know all of these draft and minor 802.11 revisions? I only see a,b,g, and draft n mentioned on the official objectives, but there are 15+ extra ones explained in my Sybex book. I'm assuming it's just extra info.

Wireless is a bit of a mess with all it's protocol variations. I try to stay away from it.

You know, I would at least be able to recite what all of the amendments to 802.11 are if a letter is thrown at you. I really don't think you'll need to know in-depth stuff on more than a, b, g, i, and n, but it doesn't hurt to memorize what the others amendments are.

Ok, that's what I thought. Thanks for the feedback.

Yup, you don't need to explain it all in-depth but you should at least know roughly what they stand for.

That would be correct. Know enough about the differences. It would take a long time to cover them all in any great depth in terms of detailed mechanics.

With the CWNA you need to have a working knowledge. But with any of the CWNP professional level stuff you need to understand how many of the amendments actually work.

I see these same ones in my CCNA book, the Wireless chapter. I noticed that not much of them were mentioned in the chapter review questions, but ... why risk it? I made flash cards on them. A few extra flash cards never killed anyone ... did they?

People may have suffered from paper cuts though.

I don't know, I've seen quite a few people around this forum who seem to have a very severe allergic reaction to learning anything that won't be covered on the exam.

But you can't/won't survive off certification knowledge alone. (I don't think you would last or week or two let alone a month)

This is very common in the certification world. Many people are interested more in the paper than actually learning anything. They see taking an exam as an annoyance rather than an opportunity, so they want to quickest way to get the certification over with. You can easily detect these people in certification classes by their continual utterance of the phrases, "Will this be on the exam?", "Do I have to know this for the exam?", and "Why would they put that on an exam?"

I don't want to promote this type of behavior but I was just going through this chapter and in the CWNA study guides and it states the exam does not cover draft amendments, with the exception of 802.11n. (kind of a contradiction but that's ok)

Either way, we all work in IT and few more IEEE standards won't kill us right?

There is a difference between draft and ratified amendments. 802.11 a, b, g, e, g, h, i, and n are all ratified and no longer draft. Anything that refers to 802.11n as draft was written before 2009.
