DOI: 10.1036/0071394680 To my wife, Jennifer, an ardent Internet and wireless user— for all your love and support. To my 16-month-old daughter, Katherine Grace, who’s already fascinated by handheld devices and will grow up know- ing only a “wireless world.” To my parents, who don’t understand the technology but nonetheless are captivated by it all—for your encouragement. Roman Dedicated to my loving wife, Peggy, and all our children David, Patrick, Amy, and Zachary. Their love, support and understanding made this book possible for without it, I could not have persevered the long nights and weekends of writing instead of spending time with the family. In memory of my late Mother and Father who taught me to set goals and strive to achieve them; and above all else, to hold an education in the highest esteem. They instilled in me that you could always learn something new. Al Dedicated to my parents, Earl and Colette Courtney, who, in addition to teaching me the value of hard work, have helped me to see that not everyone is an early adopter, and have served (albeit unknowingly) as my faithful indicator of when a particular technology was finally ready for the non-technical mainstream. Through their cautious but curious approach in adopting digital technologies, I am constantly reminded of the need for day-to-day functionality, ease of use, and above all, value for money.

However, less than 10–15% of these same people enjoy a broadband connec- tion for personal Internet access at home; the number of broadband mobile users is significantly less than that at this point. Many of these individuals who delight in high-speed access at work are disappointed with their home experience and highly disappointed with their mobile access experience. This results in a limitation of personal use or SOHO work objectives. Today, the primary options available to fixed broad- band customers are cable, DSL, satellite, or point-to-point and point-to-multipoint wireless. These are good technologies but insufficient to address all global broadband needs due to range, flexibility, or physical connection requirements. In many cases, there is a virtual monopoly of these existing broadband solu- tions that makes them expensive and potentially unattractive to the end user. Mobile users have even fewer choices for broad- band access but the marketplace is changing. Competition and market penetration require new technology for wireless mobile and fixed broadband access systems. This is the dawn of the Wireless Internet. The team here at Navini Networks believes that narrowband, slow-speed connections will be things of the past in a few years and that wireless solutions must be a sig- nificant part of that change. The world of wired telecommunications has developed for well over 100 years and continues to advance daily at an aston- ishing pace. At the same time user behavior is also evolving and untethered access is considered an increasingly important requirement. Although wireless telecommunications has exist- ed for the last 30–50 years, it only became popular with the advent of mobile cellular communications in the last 15 years. Today, the majority of voice calls are divided between cordless phones and cellular phones, skipping the basic wired phones of ix Copyright (cid:164) 2002 by The McGraw-Hill Companies, Inc.
