Even though our two adult children are grown and out of the house, I know they were thinking about me writing and cheering me on during the entire process, even with their busy schedules. I would also like to thank everyone at Sybex who helped with the creation of this book, including acquisitions editors Jeff Kellum and Kenyon Brown, production editor Christine O’Connor, copy editor Judy Flynn, editorial assistant Connor O’Brien, and editorial man- ager Pete Gaughan. I owe all these individuals a lot of gratitude for their patience with me and the several delays encountered while working with me on this book. The developmen- tal editor for this book is Kelly Talbot. Many thanks go to Kelly for his time and his work in helping with the fl ow, organization, and suggestions that allowed me to make this book an easy read. His editorial skills and attention to detail were an enormous help to me. The technical editor for this book is Denny Hughes. I want to thank Denny for his timely reviews, comments, and suggestions that helped make this book a nice read and a valuable reference source. His many years of experience as a technical trainer, engineer, and content developer were a great contribution in creating a book I am sure you will enjoy reading. A special thank you goes to contributing author Sebastian Coe for his help with Chapter 17. Sebastian’s expertise in information systems security was instrumental in his contribution. I would also like to thank the thousands of students who have taken the time to attend the computer networking classes that I have had the opportunity to teach over the past 20 years. Educating, mentoring, and entertaining so many of these individuals gave me the inspiration to author this and other books about wireless networking.
