What readers of the previous editions had to say:

"With jargon-free definitions, clear schematic drawings and its steady narrative drive,The Essential Guide to Telecommunications is a reassuring testament to the human ability to comprehend and communicate at some fundamental level even the most bewildering technology."

—David Warsh, The Boston Globe

"This book cuts through all the jargon and mysterious acronyms to give easily understood explanations of telecommunications, from the basics to the latest technology. I refer to it on a regular basis and constantly recommend it to others."

—Michael Rieke, Editor of the Dow Jones Bandwidth Intelligence Alert

"It is fair to say that Annabel Dodd has done more to demystify the industry for more people than anyone else in Massachusetts. For those who don't know bandwidth from a band saw or optical networks from an ophthalmologist, Dodd's book offers valuable insights into the products and services that fall under the telecommunications umbrella."

—Katherine Raphaelson, Director, Massachusetts Telecommunications Council

"This book is written for those who have little or no technical background. It's an easy-to-read overview of much of the technology available now and great if you have no patience for technical terminology."

—George Runkle, The Motley Fool, Inc.

Preface

Preface

Enormous changes in telecommunications occurred in the two years between the second and third editions of The Essential Guide to Telecommunications. The Essential Guide to Telecommunications is intended as a road map clarifying technologies, history and trends in telecommunications. Technological innovations in fiber optics and attendant lower costs has led to the construction of vast networks. The book contrasts the glut of these fiber optic networks in long distance routes and some urban areas with their scarcity in developing countries, rural and most suburban regions.

The Essential Guide to Telecommunications explains how technology and regulatory factors impact each other. Deregulation and the presence of competition have resulted in the development of technological innovations. These innovations, particularly those in gigabit Ethernet and optical switching, are examined.

Cellular service has grown tremendously in the last decade. It is a key technology for providing basic voice service in large parts of the world. The book examines technologies used to provide greater capacity for basic voice service in fast growing urban areas, rural communities and tall skyscrapers. It also explains the advanced cellular technologies for transmitting higher speed data and accessing the Internet over wireless networks. It also addresses the concerns about safety. It is not known what impact fears about cancer and driving safety will have on the cellular market.

The Essential Guide to Telecommunications, third edition reviews telecommunications in Europe, Asia and Latin America, as well as in developing countries, and the wide-reaching impact of wireless technology in these areas. Deregulation of local long distance and international services, as well as industry structure and major carriers, are covered. The structure of the telecommunications industry and steps in deregulation are examined in key areas of the world. The pace of adoption of technologies, such as high-speed Internet access, also is highlighted. 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, third edition presents profiles of industry segments and vendor types to provide readers an understanding of the industry. The roles of Internet service providers, backbone Internet providers, competitive local exchange carriers, utilities and cable TV companies are explained. The number of network providers and resellers and the fast pace of mergers has created new layers of complexity. In addition, regulatory rulings and the Telecommunications Act of 1996 are examined in light of their impact on consumers, commercial organizations and carriers.

The language and significance of important telecommunications technologies are explored. The Essential Guide to Telecommunications, third edition 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. Technologies important in competition for local calling, high-capacity communications, third generation wireless services and Internet access are clarified. Intertwined with high-level technical explanations are examples of how the various vendors interconnect their networks. The book explains key technologies and options available for small and large organizations and consumers. It further explores significant trends, applications and the impact of the Internet.

This book is intended for non-technical people working in the field of telecommunications, laymen interested in learning more about the field and people responsible for the administration of telecommunications services for their organizations. They include regulatory staff, salespeople, law firms, research organizations, marketing personnel, human resources professionals, project managers, telecommunications managers and high-level administrators.

The Essential Guide to Telecommunications, third edition 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.
