Acknowledgments

I would like to thank my wife, Jeannie, and two adult children, Ashley and Jason, for their support and patience during the writing of this book. They made completing this project much easier for me.

I would also like to thank everyone at Sybex who helped with the creation of this book, including acquisitions editor Jeff Kellum, production editor Eric Charbonneau, copy editor Liz Welch, editorial assistant Connor O'Brien and editorial manager Pete Gaughan. I owe all these individuals a lot of thanks for their patience while working with me on this book and keeping things on track. Jim Compton is the Development Editor for this edition of the book. Many thanks go to Jim for his time and his work in helping with the flow, organization, and suggestions that allowed me to make this book an easier read. His knowledge and attention to detail were a huge help. Also, thanks to Tom Carpenter the proofread technical editor for this edition of the book.

The Technical Editor for this edition of the book again is Bryan Harkins. I want to thank Bryan for his timely reviews, comments, and great suggestions that helped make this book a valuable reference source. His years of experience as a technical trainer, engineer, security specialist and author were a great contribution in creating a book I hope you will enjoy reading.

I would again like to thank the thousands of students who have taken the time to attend the computer networking classes I was given the opportunity to teach. Educating, mentoring, and entertaining so many of these individuals gave me the inspiration and motivation to author this book and hopefully many more.

Of course, this book would not exist if it were not for the people at CWNP. The CWNP team has realized the need for vendor-neutral wireless LAN training and certification and has done a great job of building a brand over the years that is now known worldwide.

Finally, a thank you to all the manufacturers, vendors, organizations, and individuals that provided the subject matter, allowing me the technology and tools needed to write this book.
