Description :Cellular phones, especially those enabled by second-generation telecommunication systems, have had tremendous impacts on our daily lives.
In some countries such as India, the number of cellular phone subscribers has far exceeded the number of wired phone subscribers. Meanwhile, the Internet has also significantly changed our daily lives. More and more ecommerce applications have been introduced while the number of Internet users has skyrocketed over the recent five years. The mobile workforce has also tremendously increased in size. Mobile workers expect to be able to use the Internet while on the move. However, the data handling capabilities of second-generation systems are limited. Thus, third-generation (3G) cellular systems such as UMTS (Universal Mobile Telecommunication Systems) and CDMA2000 (Code-Division Multiple Access) Systems are designed to provide high bit rate data services that enable multimedia communications.

Such third-generation cellular systems allow high-quality images and video to be transmitted and received. The third-generation cellular systems also provide open-access capabilities where value-added services, e.g., locationbased
services, can be introduced by third-party providers. While the 3G standards are being drafted, and equipment for third-generation cellular systems is being designed, wireless LAN systems are introduced into our
daily lives to meet our demand for wireless data services while on the move.
This book describes the network architectures of UMTS and CDMA2000 systems and how major network elements within the 3G networks can be designed. In addition, this book provides discussions on how the end-to-end performance for voice and data services can be determined. It also provides guidelines on how the radio access networks and core networks can be
engineered. Last but not least, this book describes the various wireless LAN standards and how voice and data services can be offered in wireless LAN systems.

The book is organized as follows:

Chapter 1 provides an introduction to wireless communication concepts. It briefly discusses the first- and secondgeneration systems that are based on Frequency Division Multiple Access (FDMA) and Time Division Multiple Access (TDMA) technologies, and the spread spectrum-based communication systems. Then, it briefly discusses common techniques used in spread-spectrum communications, e.g., power control, soft handoff, adaptive modulation and coding, and multiuser diversity.

Chapter 2 provides an introduction to wireless systems. It discusses generic wireless system architecture and how the system operates, e.g., the registration of mobile phones, how mobile phones initiate calls, how calls are delivered, what happens when mobile phone users move, and how intra/inter-system handoffs are carried out. Chapter 3 provides an introduction to traffic engineering issues. Service providers are interested in
maximizing their revenue via offerings of high-value services while maintaining high utilization of their installed infrastructure. Thus, traffic engineering is required since different applications have different quality of service requirements. Traffic models for different applications need to be developed.

Chapter 3 discusses techniques that one can use to determine the traffic models for different applications, e.g., WWW-browsing and emails. It also discusses the different parameters used to describe circuit-switched and packet-switched services.

Chapter 4 describes the network architectures for UMTS and CDMA2000 systems. Chapter 5 analyzes the airlink interface capacity and performance for UMTS/CDMA2000 systems.

Chapter 6 describes how the 3G base station can be designed to meet certain performance requirements.

Chapter 7 describes how the 3G base station controller can be designed and how the radio access networks can be
engineered. Techniques that can be used to reduce the OPEX of the radio
access networks are also discussed.

Chapter 8 describes how the core network elements can be designed.

Chapter 9 describes the end-to-end performance of voice and data services in 3G systems.

Chapter 10 provides a high-level description of the various 802.11-based wireless LAN systems.

Chapter 11 describes the medium access control (MAC) and quality of service (QoS) features in 802.11-based wireless LAN systems.

Chapter 12 discusses the upcoming 3G features.

This book is aimed at operators, network manufacturers, service providers, engineers, university students, and academicians who are interested in understanding how 3G and wireless LAN systems should be designed and engineered.
