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.

Let me start out by saying: I took and passed the CWDP test, but I've been a WiFi engineer for many years and had much more knowledge than just the data in this book to pull from. I just wanted people reading this review to know there are no sour grapes here, I took it and passed... This review is about quality and usefulness of the CWDP study guide book specifically, and not a commentary on the exam itself.

If you're considering buying this book to learn about WiFi, you could certainly do worse. They touch on many topics WiFi professionals need to think about (examples: warehouse dynamics with varying stock and ceiling mounted APs, QoS tagging, etc.). Many of the softer topics (statements of work, master service agreements, high level docs, low level docs, etc.) are HIGHLY debatable, so read those sections understanding they are general guidelines not hard and fast rules, despite the way the summary questions address the topics as hard-lined. There are things in documents, for example, that this book either doesn't address or claims are, or are not, included in the real life versions of these documents. But, it offers a decent starting point if you've never dealt with some of these document types.

But, given this book is earmarked as the study guide for the CWDP, I had to give it 2 stars. There are 15 chapters, but the actual test pulled from around 7 of them and the rest of the chapters were not covered at all on the exam (I won't discuss which, to keep exam information confidential). This exam seemed to be pulled mostly from the CWNA and CWSP, with a little bit from the CWAP. Very little actual design information was covered, just the thought process: "You need to design the network for VoIP when the requirements of the customer are for VoIP.
