Dedication
Technology has its time; knowledge is timeless.
Technowledge boosts Technowledge.
To those who idealize, conceive, standardize, implement, test, operate, main-
tain, upgrade; to those professionals, for whose knowledge and work we owe
the technology and all it conveys—to those technowledgers—I pay my most
sincere tribute.
I dedicate this book to my beloved family. Thank you, Maria N´ıdia, my pre-
cious wife, and thank you, Alexandre, Helena, Carolina, Ricardo, Vin´ıcius,
and Elisa, my wonderful children, for your love, patience, and unconditional
support.

Preface
We can always wait a bit longer to write a better book on technology. We can
always wait
In this ever-changing technological scenario, keeping pace with the rapid
evolution of wireless technology is a formidable, exciting, and indispensable
task more than a challenge. The work is indeed herculean and often dis-
couraging, for technology is vast, the number of topics to be approached is
immense, the documentation on standards and recommendations comprises
piles of uncountable pages, and we often find we are leaving something im-
portant behind when selecting the appropriate subject matter to explore. The
consolation, if any, is that as we explore the technologies, we find that much
commonality exists among them, although particular features are rather dif-
ferent in each.
The challenge of writing a book in such a “hot” and vivacious field is to
provide a clear and concise resource to accommodate the learning process of
the basic functions of the main technologies. I did try to keep this in mind
throughout the course of selection and description of the topics included in
this book. I hope I have succeeded, at least to a certain extent.
The book, divided into five parts, describes protocols, standards, and tech-
niques for 2G and 3G technologies, including those specific to wireless mul-
timedia. The first part—Introduction—contains three chapters and covers the
basic principles of wireless communications. The second part—2G Systems—
consists of two chapters and describes two leading technologies of the second
generation. The third part—Wireless Data—comprises one chapter and intro-
duces three main wireless data technologies. The fourth part—3G Systems—
encompasses three chapters and details the general concepts of third-
generation systems as well as two chief third-generation technologies. The
fifth part—Appendices—provides a glimpse at some telecommunication is-
sues that are relevant to the understanding of the main text and that are not
covered in the introductory part of the book. A more detailed description of
the book structure follows.
Part I: Introduction
Chapter 1—Wireless Network —developsthewireless network conceptswithin
the Intelligent Network framework and describes the basic functions a tele-
communication system must provide so that wireless and mobile capabili-
ties can be implemented. General network and protocol architectures and
channel structures are described that are common to the main systems. These

descriptions are based on ITU Recommendations, which generalize those con-
cepts that have been used for the various cellular networks. Specific solutions
are then detailed in the other chapters.
Chapter 2—Cellular Principles—introduces the cellular technology funda-
mentals, providing a unified approach of these concepts for narrowband
and wideband solutions. Topics explored in this chapter include universal
frequency reuse, sectorization, power control, handoff, voice activity, inter-
ference, and others. Besides the traditional hexagonal tessellation for macro-
cellular networks, the chapter examines the subject of reuse pattern for micro-
cellular systems. In addition, hierarchical cell structure, overall mean capacity
for multirate systems, and the main features of narrowband and wideband
networks are also addressed.
Chapter 3—Multiple Access—analyzes a considerable number of multiple
access control techniques. Several conventional and more advanced duplex-
ing and multiple access protocols are detailed that comply with the various
classes of traffic and multirate transmission utilized in broadband services.
The access and duplexing methods are explored in the frequency domain,
time domain, code domain, and space domain. The performance of the tech-
niques is investigated in terms of channel capacity, throughput, and delay.
Part II: 2G Systems
Chapter 4—GSM—describes the Global System for Mobile Communication
cellular network in terms of its features and services, architecture, phy-
sical channels, logical channels, signaling messages, call management, and
particular features.
Chapter 5—cdmaOne—details the features and services, architecture, phys-
ical channels, logical channels, signaling messages, call management, and
particular features for TIA/EIA/IS-95-A as well as for its evolved version
TIA/EIA/IS-95-B.
Part III: Wireless Data
Chapter 6—Wireless Data Technology—depicts three data technologies ap-
plied to wireless networks, namely, General Packet Radio Service (GPRS),
TIA/EIA/IS-95B, and High Data Rate (HDR). These technologies are de-
scribed in terms of their basic architectures and achievable data transmission
rates.
Part IV: 3G Systems
Chapter 7—IMT-2000—introduces the topic on third-generation wireless net-
works based on the International Mobile Telecommunications-2000 (IMT-
2000) concept. It describes the functional subsystems, the IMT-2000 family
concept, and the capability set concept. It also develops the network func-
tional model for IMT-2000.

Chapter 8—UTRA—details the IMT-2000 radio interface for direct
sequence code division multiple access, the so-called Universal Terrestrial
Radio Access (UTRA) or Wideband CDMA (WCDMA) 3G radio transmis-
sion technology. Descriptions include its FDD as well as its TDD options.
Chapter 9—cdma2000—details the IMT-2000 CDMA multicarrier radio
interface, the so-called cdma2000 3G radio transmission technology. Des-
criptions include its various radio configurations, the 1xEV-DO radio con-
figuration option being one of them.
Part V: Appendices
These Appendices provide tutorial information on topics such as OSI Refer-
ence Model, Signaling System Number 7, Spread Spectrum, and Positioning
of Interferers in a Microcellular Grid.
The book is suitable as text as well as a reference. As a textbook, it fits into
a semester course for both undergraduate and graduate levels in electrical
engineering, wireless communications, and more generally in information
technology. As a reference, it serves systems engineers and analysts, hard-
ware and software developers, researchers, and engineers responsible for
the operation, maintenance, and management of wireless communication
systems.
