Customer Reviews:Average Customer Rating: Poor This book really does come up way short as far as being able to prepare for the exam. The questions on the cd weren't even close to the types of questions on the actual test. In fact there were questions on things not even mentioned. Reading through the book it's obvious that it was rushed through. Simply put it's not a very good tool to use. Unfortunately there aren't many other options for anyone hoping to take the IUWNE 640-721. Book ok, exam question bank on CD grossly inadequate While the book is adequate, the supposedly "realistic exam questions" on the cd-rom miss the mark by a mile. I tried to take the exam yesterday and there was little resemblance between the questions on the cd-rom and the questions in the exam. Superficial and sometimes inaccurate I don't expect much from Cisco Press books but this one is still poor even by that standard. Knowing this book by heart will still leave you failing the exam, but it does give you a feeling for the truly nit-picky nature of the exam. As for the book, not only does it skimp on details, but there are some really funny gaffs. He cites the RFC for Everything Over IP to explain Ethernet Over IP. for the newbies using Cisco Wireless products I baught this book for my studies with Wireless Lan Controller and Cisco APs. I am not satisfied with the coverage of the subjects with this book. Cisco Wireless Lan Controller subjects are not covered well. A lot of subjects are missing. If you are newbie with the cisco wireless products you can read it otherwise it is only waste of time with reading this book. Not good enough for wireless fundamentals Perhaps this text would be appropriate for somebody seeking the CCNA Wireless certification, but this book seriously falls short on wireless and radio fundamentals. In the opening chapters the author introduces the concept of phase before he even describes a waveform and its components. It also contains a lot of inaccuracies. He goes into detail about the differences between DSSS bit rates and their associated encoding techniques but barely describes OFDM or 802.11n at all. | | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
