Acknowledgments

I would like to thank my in-laws Ann and John Barrett for providing us with a wonderful home this past year while ours was being built. Thank you, Janie, Jennifer, and Samantha, for your patience and understanding of my life on the road. To my parents, Kathy and George, thank you for almost always being willing to hop in the car and drive four hours to give a helping hand or to attend one of our many parties. I also want to say thank you to Devin Akin for introducing me to wireless in one of the first CWNA classes ten years ago, to Chris Leach for hiring me as a wireless networking trainer seven years ago, and to Carolyn Cutler for keeping me busy for the past three years.

—David A. Westcott

I would once again like to thank my children, Brantley and Carolina, for their patience and understanding of their father throughout the writing of yet another book. I love you kids very much. I would also like to thank my mother, Marjorie Barnes, and my stepfather, William Barnes, for many years of support and encouragement. I would also like to thank my brother, Rob Coleman, for all his help and support over the years.

—David D. Coleman

First and foremost, I would like to thank the God who created and sustains me and whose love and grace brings meaning and purpose to my life. I would like to thank my wife, Sarah, for the unconditional love and support she has shown me throughout the writing of this book. I would like to thank my children, Luke and Joshua, for bringing a smile to my face when I needed it the most, and I would like to thank my parents, Richard and Heather, for always believing in me.

I would like to thank my colleagues Alistair Meakin and Peter Quinn for their support during my professional career at MarQuest. I would also like to thank Riaz Khan at WildPackets and Janice Spampinato at Case Technologies for their support and contribution to this book.

To begin, it is best to start at the beginning. Thank you, Ignacio De La Torre, for starting me on the path toward a career in wireless networking. You sure pick wireless professionals better than you pick fantasy football quarterbacks. Thank you, Devin Akin, whose great gift is to inspire the ordinary into the extraordinary. I was there when you taught the world’s first CWAP course, and I’m still trying to recover. Mike Walsh, thank you for taking a chance on a 28-year-old to write a seven-figure-a-year wireless training curriculum. Also, thank you for leveling with me when I was full of it. I must thank Tori Easterly for fighting for me in spite of my orneriness and against me when that orneriness needed reins. And thank you for reminding me that hockey is great. Great thanks must be given to Jeff Kellum and Tom Cirtin for guiding me through this project. They helped me turn scattered thoughts into something legible. And finally, a hearty shout-out to a man full of good ideas and good humor, GT Hill. If I had to pick one man as my partner in a wireless venture or to ride shotgun as I plunder the local Chick-Fil-A, GT would be that man.

Writing CWAP: Certified Wireless Analysis Professional Official Study Guide has been an adventure from the start. We would like to thank all of the following individuals for their support and contributions during the entire process.

We must first thank our acquisitions editor at Sybex, Jeff Kellum, for initially finding us and bringing us onto this project five years ago. Jeff is an extremely patient and understanding editor who occasionally sends a nasty email message. We would also like to thank our development editor, Thomas Cirtin.

Although he was not available to be one of the official authors of this book, we must thank Keith Parsons for the work he did on the spectrum analysis chapter. His knowledge and insight was instrumental in helping to understand and bring together a complicated topic.

We would also like to thank everyone from the CWNP program (www.cwnp.com). You should be proud of the internationally renowned wireless certification program that you have developed. It has been a pleasure working with all of you the past decade. A special thanks goes to Marcus Burton for his feedback and content review.
