CWNA Certified Wireless Network Administrator Official ... (ISBN 0072229020)

Not a complete study guide for the PW0-100 exam:
I liked this book but as the CWNA study guide it falls short of expectations. The PoE coverage was almost entirely lacking and there were many other areas that did not fully cover the exam question areas. I wrote CWNP and received a lame excuse as to why it was not complete and to disregard the claim printed on the cover that it provided "Complete coverage of the CWNA exam objectives". They said the exam has gone through considerable changes since the book's publication and thus does not match in many areas anymore. I suggested an on-line suppliment to cover the changes and they said that was not necessary, I should research the changes myself. As the exam study guide it deserves 2 stars, as a general guide to wireless networking it deserves at least 3 or 4 though obviously it is getting dated.

False advertising.:
This "Official" study guide claims in the blue star in the upper right corner of the front cover "Complete Coverage of the Exam Objectives". In side the book, the LIMITED WARANTY states that the "study guide is believed to be reliable, BUT CANNOT BE GUARANTEED TO BE CORRECT OR COMPLETE". Is that double talk or what? I am here to tell you folks that the latter is true, and not the former. Having taken the test, I can honestly tell you that there were certain topics, terms, and phrases mentioned in the test questions that were NOT FOUND anywhere in the entire book. The test's usage agreement prohibits me from mentioning here what those subjects were. Despite the false and misleading advertising on the front cover, this book is the most comprehensive book of the subject found between 2 covers that I am aware of (with the possible exception of the 4th edition which I have not read). That said, I feel that I need to warn you of the following things. 1. If you buy this book, be sure that you download the book's errata sheet from the CWNP web site and make the corrections in the book. 2. The test objectives discussed in the book differ somewhat from those shown on the CWNP web site. Those small differences can make a big difference on the test. 3. I found the chapters on network security, network architecture, organizations and standards, and spread spectrum technologies to be somewhat confusing, and incomplete in the manner the material was presented. You will do well to supplement your studies of this book with other material, particularly the subjects mentioned previously.

Good starter:
This is a good starter if you are not familiar with the world of Wireless. It explains how radio waves work, how different objects can interfere with the radio wave, and how to setup your network. It explains the OSI model and it is written in an easy to read manner. I read the book and was able to pass the certification.

CWNA Certified Wireless Network Administrator Official Study Guide (Exam PW0-100), Third Edition (Planet3 Wireless):
CWNA is a newish International Certification in ICT. I have been working with International Certification in ICT for a long time, and I have read many books. This book cuts to the chase succinctly and very well. In a reasonably newish field (Wireless Networking), I have yet to find a publication as well organised as this one. The book is useful for many things -- a reference, a text book or a study book. A great effort, and I hope there will be more to come

A True Gem of a book!:
This is the book I read which took me from no knowledge of wireless LAN technology, to a good understanding of the subject in a highly accessible way and also ignited my current interest in wireless. This 3rd Edition of the CWNA Study Guide is incredibly well written with lucid concise explanations blended in with fantastic and clear diagrams. From what I've seen of the 4th Edition so far (I'm still labouring through that), you definitely DO NOT want to throw the 3rd Edition away if you've already got it. It's likely to become a collector's item even though it's a bit dated in terms of how current the contents are, however it is a much higher quality text than the new 4th Edition of the CWNA Study Guide in spite of the fact that the new edition has many more words in it. I found myself referring back a lot both to the 3rd Edition and the CWNA book by the 2 David's for clarification of several areas which were not explained well in the later edition. Having said that unfortunately you will probably need the 4th Edition to prepare for the CWNA certification as it does seem to cover newer areas of the CWNA syllabus. I strongly recommend this 3rd Edition if you want a solid understanding of 802.11 Wireless LAN technology regardless of whether or not you intend to take the certification exam.
