DOWNLOAD EBOOKCommunications policy as been a fertile area for testing theories of regulation, subsidy and incentives, free speech, political participation, and the public interest. The capacities of new communications technology have changed markedly since much of the governing legislation in the communications field was written. Such a change is likely to continue and have considerable impact on specific communications sectors and in communications policy. This two volume set of analyses undertakes a review of telecommunications policy in transition--of actions taken and not taken, of goals pursued or ignored, of the adequacy of policy vehicles and their strengths and weaknesses. The authors evaluate three categories of policy problems: those of concept, scope, and judgment in communications policy; those specific to media industries and forces affecting them; and those concerning wider public policy concerns intersecting with communication.

DOWNLOAD EBOOKThe state of the art of modern lightwave system design Recent advances in lightwave technology have led to an explosion ofhigh-speed global information systems throughout the world.Responding to the growth of this exciting new technology, LightwaveTechnology provides a comprehensive and up-to-date account of theunderlying theory, development, operation, and management of thesesystems from the perspective of both physics and engineering. The first independent volume of this two-volume set, Components andDevices, deals with the multitude of silica- andsemiconductor-based optical devices. This second volume,Telecommunication Systems, helps readers understand the design ofmodern lightwave systems, with an emphasis on wavelength-divisionmultiplexing (WDM) systems. * Two introductory chapters cover topics such as modulation formatsand multiplexing techniques used to create optical bitstreams * Chapters 3 to 5 consider degradation of optical signals throughloss, dispersion, and nonlinear impairment during transmission andits corresponding impact on system performance * Chapters 6 to 8 provide readers with strategies for managingdegradation induced by amplifier noise, fiber dispersion, andvarious nonlinear effects * Chapters 9 and 10 discuss the engineering issues involved in thedesign of WDM systems and optical networks Each chapter includes problems that enable readers to engage andtest their new knowledge to solve problems. A CD containingilluminating examples based on RSoft Design Group's award-winningOptSim optical communication system simulation software is includedwith the book to assist readers in understanding design issues.Finally, extensive, up-to-date references at the end of eachchapter enable students and researchers to gather more informationabout the most recent technology breakthroughs andapplications. With its extensive problem sets and straightforward writing style,this is an excellent textbook for upper-level undergraduate andgraduate students. Research scientists and engineers working inlightwave technology will use this text as a problem-solvingresource and a reference to additional research papers in thefield.

DOWNLOAD EBOOKThe use of radio-frequency communication-commonly referred to as wireless communication-is becoming more pervasive as well as more economically and socially important. Technological progress over many decades has enabled the deployment of several successive generations of cellular telephone technology, which is now used by many billions of people worldwide; the near-universal addition of wireless local area networking to personal computers; and a proliferation of actual and proposed uses of wireless communications. The flood of new technologies, applications, and markets has also opened up opportunities for examining and adjusting the policy framework that currently governs the management and use of the spectrum and the institutions involved in it, and models for allocating spectrum and charging for it have come under increasing scrutiny. Yet even as many agree that further change to the policy framework is needed, there is debate about precisely how the overall framework should be changed, what trajectory its evolution should follow, and how dramatic or rapid the change should be. Many groups have opinions, positions, demands, and desires related to these questions-reflecting multiple commercial, social, and political agendas and a mix of technical, economic, and social perspectives. The development of technologies and associated policy and regulatory regimes are often closely coupled, an interplay apparent as early as the 1910s, when spectrum policy emerged in response to the growth of radio communications. As outlined in this report, current and ongoing technological advances suggest the need for a careful reassessment of the assumptions that inform spectrum policy in the United States today. This book seeks to shine a spotlight on 21st-century technology trends and to outline the implications of emerging technologies for spectrum management in ways that the committee hopes will be useful to those setting future spectrum policy.

DOWNLOAD EBOOKWith optical fiber telecommunications firmly entrenched in the global information infrastructure, a key question for the future is how deeply will optical communications penetrate and complement other forms of communication (e.g., wireless access, on-premises networks, interconnects, and satellites). Optical Fiber Telecommunications, the seventh edition of the classic series that has chronicled the progress in the research and development of lightwave communications since 1979, examines present and future opportunities by presenting the latest advances on key topics such as: - Fiber and 5G-wireless access networks - Inter- and intra-data center communications - Free-space and quantum communication links Another key issue is the use of advanced photonics manufacturing and electronic signal processing to lower the cost of services and increase the system performance. To address this, the book covers: - Foundry and software capabilities for widespread user access to photonic integrated circuits - Nano- and microphotonic components - Advanced and nonconventional data modulation formats The traditional emphasis of achieving higher data rates and longer transmission distances are also addressed through chapters on space-division-multiplexing, undersea cable systems, and efficient reconfigurable networking. This book is intended as an ideal reference suitable for university and industry researchers, graduate students, optical systems implementers, network operators, managers, and investors. Quotes: "This book series, which owes much of its distinguished history to the late Drs. Kaminow and Li, describes hot and growing applied topics, which include long-distance and wideband systems, data centers, 5G, wireless networks, foundry production of photonic integrated circuits, quantum communications, and AI/deep-learning. These subjects will be highly beneficial for industrial R&D engineers, university teachers and students, and funding agents in the business sector." Prof. Kenichi IgaPresident (Retired), Tokyo Institute of Technology "With the passing of two luminaries, Ivan Kaminow and Tingye Li, I feared the loss of one of the premier reference books in the field. Happily, this new version comes to chronicle the current state-of-the-art and is written by the next generation of leaders. This is a must-have reference book for anyone working in or trying to understand the field of optical fiber communications technology."Dr. Donald B. Keck Vice President, Corning, Inc. (Retired) "This book is the seventh edition in the definitive series that was previously marshaled by the extraordinary Ivan Kaminow and Tingye Li, both sadly no longer with us. The series has charted the remarkable progress made in the field, and over a billion kilometers of optical fiber currently snake across the globe carrying ever-increasing Internet traffic. Anyone wondering about how we will cope with this incredible growth must read this book." Prof. Sir David Payne Director, Optoelectronics Research Centre, University of Southampton - Updated edition presents the latest advances in optical fiber components, systems, subsystems and networks - Written by leading authorities from academia and industry - Gives a self-contained overview of specific technologies, covering both the state-of-the-art and future research challenges
