In 1993, the United States Federal Communications Commission (FCC) allocated a total of 140 MHz of frequency bands in the vicinity of 2 GHz to be used for PCS. In 1994, the FCC started auctioning licenses to operate PCS in these frequency bands, and, at the time of this writing, the auction is continuing. With these two pivotal actions by the FCC, PCS has taken a big step toward its realization. Because of the inherent nature of mobility, which is characteristic of personal communications, wireless communications and PCS have become inseparable concepts. In particular, PCS will critically depend on wireless technologies for the mobile-to-network access portion of the service, which is referred to as the common air interface. The topic of this book is the wireless access technology used for the common air interface in order to support PCS. The purpose of this book is two-fold: 1. First, this book presents clear tutorial expositions of main digital technology elements employed for wireless access systems. The main objective here is to pull together all the important basic technical elements necessary in understanding wireless access systems at one place so that the reader can obtain an overall view of the technology quickly and systematically. 2. The second purpose of this book is to review the common air interface standards for PCS. There are literally thousands of pages devoted to the PCS common air interface standards. These standards documents are intended for experts who are familiar with not only the underlying technologies but also the process and x PREFACE rationale behind the written words. These reading-between-the-lines aspects are not obvious in the written words of the standards and can be very cryptic to an average reader. With respect to reviewing the standards, this book has two main objectives. The first objective is to sift out and summarize important elements of the standards, which are buried in the veritable mountain of paper in all too unfamiliar terms, notations, and abbreviations. The second objective is to expand, almost paradoxically, some of the more important elements to explain the intent and significance of the written words of the standards. In order to accomplish the second objective, various means are used. Many supporting diagrams have been provided to illustrate important points and explain underlying concepts. In other instances, some of the diagrams and tables of the standards are expanded to provide details. The detailed discussion of the standards is provided using two main standards as examples, one TDMA standard, and one CDMA standard. For other standards, highlights of key elements of the standards are presented. This book is written for two primary audiences: 1. Managers and professionals involved in personal and wireless communications. This book will provide them with a quick means of obtaining a comprehensive picture of overall aspects which are important in the area. 2. Students and professors in the communications field. This book can be used as a text for a one-semester wireless communications course in a graduate school curriculum of electrical engineering.

In the recent past, however, wireless communications has witnessed an explosion of renewed interest from consumers for its application for mobile and personal communications. Cellular phones are now widely used by all types of consumers - business men and women, housewives, college students, and teenagers. As the demand for more sophisticated mobile and personal communications services increases, the existing cellular systems face limitations. Personal Communications Services (PCS) is a new concept which will expand the horizon of wireless communications beyond the limitations of current cellular systems to provide users with the ability to communicate "with anyone, anywhere, anytime." In 1993, the United States Federal Communications Commission (FCC) allocated frequency bands for PCS. In 1994, the FCC started auctioning licenses to operate PCS in these frequency bands, and, at the time of this writing, the auction is continuing. With these two pivotal actions by the FCC, PCS has taken a big step toward its realization. Because of the inherent nature of mobility associated with personal communications, wireless communications and PCS have now become almost inseparable concepts. PCS will critically depend on, among other things, wireless technologies, particularly for the mobile-to-network access portion of the service, which is referred to as the common air interface. The topic of this book is the wireless access technology used for the common air interface in order to support PCS. This book first presents clear tutorial expositions of essential building blocks of the digital wireless communications technology. It then provides in-depth examples of
