I should admit it was not an easy reading for me because my background in RF systems and design is close to 0 but it was useful for general understanding of the wireless technologies.
I like the simplicity of explanation of radio path loss and geometric interpretation of it.
Multipath and diversity resonated well with me because I am currently looking at P2P networks for VoIP kind of applications where I am also facing problems of reliability and trying to solve them with redundancy. Also I got a lot of food for thought in a section about 802.11n where I read for the first time about MIMO protocol. (Well, I realize that I may sound too ignorant but at least sincere).
Modulation and Coding were a nice refresher for me from old school days as well as a chapter about noise measurement were dB was described. I do not think I learned about dBm or DBi before.
I have found Chapter 7 both useful and practical for myself. I learned that a coax cable is essentially a capacitor, a discussion about reflection in RF design and return loss was engaging and easy to understand. I gained some knowledge of connectors that I may be able to use at my work. And, of course, I liked to learn more about different types of antennas, dipole, rubber duck, patch, parabolic dish, horn (my understanding is that it is not practically used but as a component of dish antennas), phased array, and Yagi. I think I will be able to tell one from another when I see them in the field. I already mentioned 80211.n. I felt good about myself :) when I understood why 802.11n is back compatible and why when multiple frames a combined in a singe one it increases throughput when SNR is high but may be a bad idea if communication link is dirty.
The book gave me a chance to look at the low level part of the stack which I had no visibility before.
I recently started reading the CWDP Study Guide and I have to say that this book is impressive. I personally know three of the authors, so I knew before I even picked up the book, that a solid Wi-Fi brain trust had been assembled to write the book.
That being said, I have seen some really smart IT professionals fail miserable when it comes to writing a book about complex technology such as 802.11 technology.
Chapter 3 "Designing for Applications" is a must read. There is a wealth of information in this chapter alone.
Chapter 5 is by far the most current description available anywhere about the multitude of WLAN architectures that exist and continue to evolve.
Oh... an entire chapter (14) about "Post-Installation Validation" - Talk about an important real-world chapter!
I have co-authored three books about Wi-Fi and it takes a lot to impress me. I also understand how hard it is to deliver a quality content in a book when the only concern the editor has is to rush completion to meet publishing deadlines.
The CWDP Study Guide content validates the hard work that the authors have delivered admirably.
Consider this book to be a 'must-have" for reference purposes as well as a study guide.

It doesn't matter if you are a network professional or just a beginner in wireless networking. This is the ultimate book for newbies and pros. It gives you what you need to not only pass the exam, but actually be able to work on large and small scale wireless networks.
Trust me, I know. I build WiFi networks for sports stadiums all across the USA and I own this book.
