Focusing on qualitative descriptions and realistic explanations of relationships between wireless systems and performance parameters, INTRODUCTION TO WIRELESS AND MOBILE SYSTEMS, 4e explains the general principles of how wireless systems work, how mobility is supported, what the underlying infrastructure is and what interactions are needed among different functional components. Rather than offering a thorough history of the development of wireless technologies or an exhaustive list of work being carried out, the authors help computer science, computer engineering, and electrical engineering students learn this exciting technology through relevant examples, such as understanding how a cell phone starts working as soon as they get out of an airplane. This edition offers the most extensive coverage of Ad Hoc and Sensor Networks available for the course and includes up-to-date coverage of the latest wireless technologies. Important Notice: Media content referenced within the product description or the product text may not be available in the ebook version.

Mobile systems - primarily cellular telephony - have been the fastest moving telecommunications development to date with a world-wide customer base that in the ten or so years to April 1996 reached 100 million and continues with a current growth rate of 60% per annum world-wide. Predictions suggest that the customer base will exceed 1 billion within the next ten years and that the saturation level is around 80% of any population. Faced with such statistics any book such as this can proffer little more than a snapshot of the activities and developments that are at present taking place within the mobile world. It can, however, reflect on some of the underlying principles that support the industry. The opening chapter offers a vision for the future of mobile communications - that of more mobile than fixed connections to the world's telecommunica tions networks - one which, interestingly, pre-dates the emergence of the information superhighway. The Internet whose growth of computer networks has, in recent years, exceeded that of even mobile systems is demanding ever more bandwidth to support its multimedia applications and access for people on the move. The communications needs of the next century customer are the driv ers behind the convergence of computing and telecommunications networks, the mobile component of which will be realized as Third Generation Mobile Sys tems (fGMS).

Many wireless systems like GSM, GPRS, UMTS, Bluetooth, WLAN or WiMAX offer possibilities to keep people connected while on the move. In this flood of technology and claims that one single resource will serve all our needs, this book seeks to enable readers to examine and understand each technology, and how to utilise several different systems for the best results. Communication Systems for the Mobile Information Society not only contains a technical description of the different wireless systems available today, but also explains the thoughts that are behind the different mechanisms and implementations; not only the 'how' but also the 'why' is in focus. Thus the advantages and also limitations of each technology become apparent. Provides readers with a solid introduction to major global wireless standards and compares the different wireless technologies and their applications Describes the different systems based on the standards, their practical implementation and the design assumptions that were made The performance and capacity of each system in practice is analyzed and explained, accompanied with practical tips on how to discover the functionality of different networks by the readers themselves Questions at the end of each chapter and answers on the accompanying website make this book ideal for self study or as course material Illustrated with many realistic examples of how mobile people can stay in touch with other people, the Internet and their corporate intranet This book is an essential resource for telecommunication engineers, professionals and computer science and electrical engineering students who want to get a thorough end-to-end understanding of the different technical concepts of the systems on the market today.

This book describes the 5G mobile network from a systems perspective, focusing on the fundamental design principles that are easily obscured by an overwhelming number of acronyms and standards definitions that dominate this space. The book is written for system generalists with the goal of helping bring up to speed a community that understands a broad range of systems issues (but knows little or nothing about the cellular network) so it can play a role in the network's evolution. This is a community that understands both feature velocity and best practices in building robust scalable systems, and so it has an important role to play in bringing to fruition all of 5G's potential. In addition to giving a step-by-step tour of the design rationale behind 5G, the book aggressively disaggregates the 5G mobile network. Building a disaggregated, virtualized, and software-defined 5G access network is the direction the industry is already headed (for good technical and business reasons), but breaking the 5G network down into its elemental components is also the best way to explain how 5G works. It also helps to illustrate how 5G might evolve in the future to provide even more value. An open source implementation of 5G serves as the technical underpinning for the book. The authors, in collaboration with industrial and academic partners, are working towards a cloud-based implementation that takes advantage of both Software-Defined Networking (SDN) and cloud-native (microservice-based) architectures, culminating in a managed 5G-enabled EdgeCloud-as-a-Service built on the components and mechanisms described throughout the book.
