Preface The world has changed since the previous edition of this book was published in 2001. People are more mobile, and carriers and customers use more of the technologies such as voice over IP and high-speed networks that were discussed as emerging services in earlier editions. The world has become smaller as a result of the increasing availability of high-speed networks, and changes are occurring in developing countries as well as Europe, North America, and technologically savvy countries in Asia and the Middle East. Increasingly, carriers that build and support these networks are large conglomerates with worldwide scope. Many carriers are expanding internationally and merging to achieve growth and economic clout. However, growth, competition, and expanded Internet access present challenges to customers and carriers. These challenges include security risks and competitors' abilities to differentiate their services without entering into pricing wars with attendant low margins. The Essential Guide to Telecommunications, Fourth Edition tracks technological advances and delineates challenges carriers face. It examines these issues in both wireline and wireless services. The Essential Guide to Telecommunications examines technological and business issues. It provides real-life examples of how consumers, small- and medium-sized organizations, and enterprise customers use technologies. It also discusses critical factors that influence customers' and carriers' adoption of new technology. Technologies covered include voice over IP, personal area wireless networks (PANs) that cover short distances within buildings, Wi-Fi wireless networks, high-speed wireless broadband, and next generation mobile services. The Fourth Edition examines next generation wireless mobile technologies capable of carrying vast amounts of high-speed data and video traffic. It also discusses basic cellular technologies and technological advances enabling one-third of the world's population to afford and own mobile phones. Mobile services provide low-cost, basic voice service in large parts of the world where in many instances a mobile phone is the first phone that customers own. In addition to exploring trends, the book provides a high-level overview of the architecture of next generation and current cellular networks, including mobile switches, softswitches, media gateways, and base stations. It also explains new wireless technologies used in sensor networks to control heating, lights, inventory levels, and manufacturing processes. It compares the differences and similarities between wireless technologies such as Zigbee, Bluetooth, and Radio Frequency Identification (RFID) in terms of the technological differences as well as the way these technologies are used. The significance of a strong telecommunications infrastructure on the economy and on international trade is widely recognized and has prompted governments' attention worldwide. The Essential Guide to Telecommunications reviews regulatory issues that are of concern to carriers and governments. It explores the role of regulations in promoting innovation and competition and robust networks critical to national security. In addition, regulatory rulings are examined in light of their impact on customer segments and carriers. The Essential Guide to Telecommunications presents profiles of industry sectors including cable TV providers, incumbent telephone companies, wireless carriers, Voice over IP carriers, and competitive local exchange carriers. It explores strategies carriers deploy to gain a competitive edge and the network technologies used to further these strategies. In addition to looking at the architecture of wireless networks, the book depicts networks based on Internet protocol (IP) as well as traditional circuit switched and signaling systems that tie networks together and link applications to users. It also explores how IP networks are connected to other carriers' IP networks and to public switched telephone networks. In addition to wireless services and the structure of carriers' networks, The Essential Guide to Telecommunications analyzes equipment and technologies used in enterprises and in homes. It explains how converged telephone systems are used--their architecture and the connection to applications such as speech recognition, instant messaging, and multi-media messaging. Also, the impact of and technological advances in local area networks and fiber optic cabling are explained. The language and significance of important telecommunications technologies are explored. It is not intended to be a deeply technical book. Rather, it is an overview of technologies and an explanation of the structure of the telecommunications industry. It also includes quotes and interviews with staff at key organizations, who express their views of how technologies, the Internet, and regulations have impacted and will continue to influence the industry. This book is intended for nontechnical people who work in the field of telecommunications, teach at and attend classes at educational institutions, and those responsible for the administration of telecommunications services for their organizations. The intended audience includes regulatory staff, salespeople, attorneys, researchers, marketing personnel, human resources professionals, project managers, instructors, telecommunications managers, and high-level administrators. The Essential Guide to Telecommunications starts out with interpretations of fundamental concepts so that readers will have a basis for understanding more complex, new telecommunications services. It examines the structure of the industry, local competition, regulatory proceedings, the Internet, convergence, and wireless services. Along with explanations of technology are examples of applications and historical highlights. How the industry evolved and how the technology changed is explained. The stories and descriptions that accompany the technical details are key to the book. (c) Copyright Pearson Education. All rights reserved.
