The evolution of cellular based mobile communication systems, from the first generation (analogue) to the second generation (digital), has been made possible by solving many technical issues along the way. Efforts to develop a global standard for providing high-speed, high quality multimedia services have crystallised in the form of the third generation (3G) systems under the IMT 200 standard. The world's first 3G system has been implemented by Japan based on the latest research results and other countries are expected to follow from 2002 onwards. 3G systems are expected to bring about radical socio-economic and cultural changes that would affect people around the world. This volume reviews in detail the basic technologies applied to W-CDMA, a standard 3G mobile communications technology. The focus is to explain in layman's language the technologies that will play an important part in future developments, with reference to the latest research results.

Now in its fifth edition, the bestselling book on UMTS has been updated to cover 3GPP WCDMA and High Speed Packet Access (HSPA) from Release 99 to Release 9. Written by leading experts in the field, the book explains HSPA performance based on simulations and field experience, and illustrates the benefits of HSPA evolution (HSPA+) both from the operators and from the end user?s perspective. It continues to provide updated descriptions of the 3GPP standard including the physical layer, radio protocols on layers 1-3 and a system architecture description. The challenges and solutions regarding terminal RF design are also discussed, including the benefits of HSPA+ power saving features. There is also the addition of a new chapter on femto cells as part of the updates to this fifth edition. Key updates include: HSPA evolution (HSPA+); Multicarrier HSPA solutions; HSPA femto cells (home base stations); TD-SCDMA system description; Terminal power consumption optimization. Updated description of LTE

Publisher Description

In this book; Chapter 1 introduces about the field of Mobile Computing, presents a short history and challenges for research, and concludes with a market vision, which shows the potential of mobile technology. Chapter 2 follows mobile IP, the extension of the Internet Protocol (IP) into the mobile domain. Ad-hoc networks with their requirements for specific routing protocols are also covered. The subsequent layer, the transport layer, is covered in Chapter 2. This chapter discusses several approaches of adapting the current transmission control protocol (TCP), which is well known from the Internet, to the special requirements of mobile communication systems. Chapter 3 comprises the global system for mobile communications (GSM) as today's most successful public mobile phone system, cordless phone technology, trunked radios, and the future development with the universal mobile telecommunications system (UMTS). Chapter 4 follows the classical layers of communication systems and explains the basics of wireless technology from a computer science point of view. Topics in this chapter are signal propagation, multiplexing, and modulation. Profound electrical engineering knowledge is not required; however, it is necessary to comprehend the basic principles of wireless transmission to understand the design decisions of higher layer communication protocols and applications. Chapter 5 and 6 depicts that Ad hoc networks are a key to the evolution of wireless networks. They are typically composed of equal nodes that communicate over wireless links without any central control. Ad hoc wireless networks inherit the traditional problems of wireless and mobile communications, such as bandwidth optimization, power control, and transmission quality enhancement. Chapter 7 discusses handoff, which is the mechanism for transferring an ongoing call from one base station to another as a user moves through the coverage area of a cellular system. It must be fast and efficient to prevent the quality of service from degenerating to an unacceptable level. Chapter 8 reviews existing solutions to the location management problem. Chapter 9 introduces mobile number portability. We describe and analyze number portability routing mechanisms and their implementation costs. We first describe the Signaling Relay Function based solution for call-related and non-call-related routing. Chapter 10 surveys data management schemes in wireless mobile environments. Mobile computing can possibly be viewed as a variation of traditional distributed computing from the data management point of view. In general, there are two possible scenarios.

WCDMA (Wideband Code Division Multiple Access), an ITU standard derived from code division multiple access (CDMA) is officially known as IMT-2000 direct spread. WCDMA is a third generation mobile wireless technology offering much higher data speeds to mobile and portable wireless devices than commonly offered in today’s market. WCDMA is a relatively new technology and there is little information in the public domain about specific design issues. The proposed book will discuss UMTS/WCDMA from the perspective of a potential development engineer, who may have experience of GSM but none of WCDMA technology. The book will outline the design specifications and potential problems and solutions faced by by an engineer designing a mobile device such as a handset. WCDMA: Requirements and Practical Design: Offers in-depth coverage of the critical issues in designing a UMTS handset modem. Discusses the practical design elements of a UMTS modem. Authored by leaders in their field, working at Ubinetics. Highly relevant to professional software engineers, Design engineers, Electrical engineers (RF base-band, DSP software, protocol software), technical managers, postgraduate students and academics.

This book explores the role of digital information and communications technology in South Korea’s development, starting with and building upon the crucial developments of the 1980s. Its perspective draws on the information society concept and on a conceptual model of strategic restructuring of telecommunications. It also draws on firsthand experience in formulating and implementing policies. The analysis identifies aspects of the Korean experience from which developing countries around the world might benefit. Oh and Larson describe the revolutionary developments of the 1980s including the TDX electronic switching system, a major surge forward in semiconductors, the start of privatization and color television and the thoroughgoing restructuring of Korea’s telecommunications sector. They further explore government leadership, the growing private sector and international trade pressures in the diffusion of broadband, mobile communication, and convergence toward a ubiquitous network society. The role of education in these developments is explored in detail, along with both the positive and negative aspects of Korea’s vibrant new digital media. The book also looks at Korea’s growing international involvement, its role in efforts to build a world information society, and finally, its future place in cyberspace. This book will be of interest to students, scholars and policy makers interested in communications technologies, Asian/Korean Studies and development studies.
