GSM (Global System for Mobile communication) provides a service to more than 500 million users throughout 168 countries worldwide. It is the world market leader serving 69 0f all mobile digital users and is currently evolving into UMTS (Universal Mobile Telecommunication System). By describing the critical decisions and the phases of the development this key text explains how the GSM initiative became a success in Europe and how it evolved to the global mobile communication system. Initially the strategy and technical specifications were agreed for Europe and the subsequent evolution to a global solution was achieved by incorporating all non-European requirements and by inviting all committed parties worldwide to participate. The process started in 1982 and the first GSM networks went into commercial service in 1992. The first UMTS networks are expected in 2002 and the fourth generation discussions have begun. * Presents a complete technical history of the development of GSM and the early evolution to UMTS * Clarifies the creation of the initial GSM second generation system in CEPT GSM, the evolution to a generation 2.5 system in ETSI SMG and the evolution to the Third Generation (UMTS) in ETSI SMG and 3GPP * Covers all of the services and system features together with the working methods and organisational aspects GSM and UMTS provides an interesting and informative read and will appeal to everyone involved in the mobile communications market needing to know how GSM and UMTS technologies evolved. The accompanying CD-ROM provides nearly 500 reference documents including reports of all standardisation plenary meetings, strategy documents, key decisions, the GSM Memorandum of Understanding and the report of the UMTS Task Force.

Understand the essentials of CDMA wireless technology and develop the knowledge you need to design and operate either co-located AMPS and CDMA or dedicated CDMA systems with this unique reference. Drawing upon his recent experience in building the first major CDMA network in North America, the author helps you acquire the knowledge you need to engineer and implement an IS-95 based CDMA system. Examining both the theoretical and practical side of CDMA engineering, this comprehensive guide is an excellent resource for practicing RF and system engineers who will find the modular-oriented chapters on spread-spectrum multiple access technique, design and performance engineering, CDMA traffic engineering, and regulatory implications especially useful. Engineering managers and directors seeking proficiency in CDMA technology will appreciate the author's ability to supply a "big picture" perspective where only the most important and relevant information to designing and optimizing a CDMA system is presented. A systemic approach makes this an ideal book for use in technical training and academic classes.

Introduction to Mobile Telephone Systems: 1G, 2G, 2.5G, and 3G Technologies and Services

This book explains the different types of mobile telephone technologies and systems from 1st generation analog to 3rd generation digital broadband. It describes the basics of how they operate, the different types of wireless voice, data and information services, key commercial systems, and typical revenues/costs of these services. Mobile telephone technologies, systems, and services have dramatically changed over the past 2 years. New technology capabilities and limited restrictions (deregulation) are allowing existing systems to offer new services. Many of these new services compete with other types of wireless systems that have not experienced significant competition. While new competition has provided lower cost services for consumers, it means a rapidly changing marketplace for the wireless industry. Some of these changes include the increase in mobile telephone customers from 300 million to 1.3 billion customers within 5 years and the shift of focus from adding new voice customers to providing advanced services such as data transfer, web browsing, and software downloads. The types of services that mobile telephone systems can offer vary depending on the technologies, devices, and the services selected by customers. This book discusses the different types of systems including 1st, 2nd, 2.5, and third generation wireless (3G). Some of the most important topics featured are: • Simple descriptions and diagrams of analog and digital mobile telephone systems • The key types of wireless services and which types of mobile telephone systems can offer them • The approximate usage fees for mobile telephone services • The market numbers and trends for mobile subscribers • How each mobile telephone system continues to change to offer new services and better compete against other mobile telephone technologies. • What are the key applications driving the mobile telephone market growth. • What are the next steps in mobile telephone systems such as 4G

Mobile robots range from the teleoperated Sojourner on the Mars Pathfinder mission to cleaning robots in the Paris Metro. Introduction to Autonomous Mobile Robots offers students and other interested readers an overview of the technology of mobility—the mechanisms that allow a mobile robot to move through a real world environment to perform its tasks—including locomotion, sensing, localization, and motion planning. It discusses all facets of mobile robotics, including hardware design, wheel design, kinematics analysis, sensors and perception, localization, mapping, and robot control architectures. The design of any successful robot involves the integration of many different disciplines, among them kinematics, signal analysis, information theory, artificial intelligence, and probability theory. Reflecting this, the book presents the techniques and technology that enable mobility in a series of interacting modules. Each chapter covers a different aspect of mobility, as the book moves from low-level to high-level details. The first two chapters explore low-level locomotory ability, examining robots' wheels and legs and the principles of kinematics. This is followed by an in-depth view of perception, including descriptions of many "off-the-shelf" sensors and an analysis of the interpretation of sensed data. The final two chapters consider the higher-level challenges of localization and cognition, discussing successful localization strategies, autonomous mapping, and navigation competence. Bringing together all aspects of mobile robotics into one volume, Introduction to Autonomous Mobile Robots can serve as a textbook for coursework or a working tool for beginners in the field.
