There's a few people in the SomethingAwful IT cert thread that have taken the CCNA:Wireless exam, and the last two failed the first attempt. If you don't have recent WLC experience or a solid grasp of RF fundamentals, you're better off waiting for the new book to be released. Some of the questions are...unfair to people who could otherwise deploy a network (topics like CCX, Apple device wireless capabilities, regulatory domains, etc). I plan to knock out as many CCNP Security exams as possible before they retire in April, but after that I'll be doing the Wireless exam.

Autonomous AP's pretty much run a specialized version of IOS, IMO, it's much more IOS-like then say an ASA or PIX with a bit of radio management on top. The WLC on the other hand, is a bit finicky to deal with if you are coming from pure IOS land. So beyond the RF specific knowledge, I expect you to need to know abit about the WLC especially since that is still basically Airespace and not IOS-ified that much. Still, all in all, it's pretty simple and at least the first course in barely touched the CLI at all. And if you worked with any form of LWAPP before, it should be decently easy.
Looking in on the IUWNE it seems it might be around 50%-ish cisco-specific knowledge, give or take a few perscent, mostly attributed to setting up and operating WLC/WCS based solutions.

Personally, what I've seen trip up most of the networking people are actually the RF-specific parts. I have a friend that works on radio side of things, that is, large radio installations that have nothing to do with network and uses tons if different antennas, filters, channel and frequency, mixing equipment, analogue transmission over fiber for backhaul, etc. The thing is it seems that the underlying fundamentals of radio are quite different from what most networking people are used to think about. And it seems that earlier standards was more networking people trying to do radio, while latter is a more mature standard. But the RF part is what is hard about wireless, and what seems to trip up most people that I've worked with when it comes to wireless.
On a side-note, what might complicate things further on is that they have started integrating WLC functionality in their higher end Layer2/3-access switches like the 3650. And personally, I think this is where we might be headed. Whether this is enabled by the fact that newer hardware run IOS as a process on top of a linux-based on IOS XE based hardware i leave unsaid, but I expect it have some bearing on it. Dont expect it to have any bearing on the current crop of CCNA wireless though, but might be good to know, nontheless.
