Book Description
Commemorating the 25th anniversary of the Telecommunications Policy Research Conference (TPRC), this volume begins with a historical survey of a quarter-century of TPRC meetings as one measure of change in and research about the telecommunications industry. Additional papers reflecting the ongoing pace of change in technological, economic, and policy issues are organized around four topics: * economic analysis of local and international telephone policy; * media industry studies including video competition, guidelines for children's educational television, and the setting of AM stereo standards; * applications and policy regarding the Internet; and * comparative studies in telephone and satellite policy. Collectively, the contents of this volume assess key issues for scholars, policymakers, and practitioners. Research reported in this volume illustrates the continually expanding scope of scholarly concerns about the telecommunications and information industry and contributes to further policy research and analysis.

Book Description
Translates technical jargon into practical business communications solutions This book takes readers from traditional voice, fax, video, and data services delivered via separate platforms to a single, unified platform delivering all of these services seamlessly via the Internet. With its clear, jargon-free explanations, the author enables all readers to better understand and assess the growing number of voice over Internet protocol (VoIP) and unified communications (UC) products and services that are available for businesses. VoIP and Unified Communications is based on the author's careful review and synthesis of more than 7,000 pages of published standards as well as a broad range of datasheets, websites, white papers, and webinars. It begins with an introduction to IP technology and then covers such topics as: Packet transmission and switching VoIP signaling and call processing How VoIP and UC are defining the future Interconnections with global services Network management for VoIP and UC This book features a complete chapter dedicated to cost analyses and payback calculations, enabling readers to accurately determine the short- and long-term financial impact of migrating to various VoIP and UC products and services. There's also a chapter detailing major IP systems hardware and software. Throughout the book, diagrams illustrate how various VoIP and UC components and systems work. In addition, the author highlights potential problems and threats to UC services, steering readers away from common pitfalls. Concise and to the point, this text enables readers—from novices to experienced engineers and technical managers—to understand how VoIP and UC really work so that everyone can confidently deal with network engineers, data center gurus, and top management.

Book Description
"This book is like a good tour guide.It doesn't just describe the major attractions; you share in the history, spirit, language, and culture of the place." --Henning Schulzrinne, Professor, Columbia University Since its birth in 1996, Session Initiation Protocol (SIP) has grown up. As a richer, much more robust technology, SIP today is fully capable of supporting the communication systems that power our twenty-first century work and life. This second edition handbook has been revamped to cover the newest standards, services, and products. You'll find the latest on SIP usage beyond VoIP, including Presence, instant messaging (IM), mobility, and emergency services, as well as peer-to-peer SIP applications, quality-of-service, and security issues--everything you need to build and deploy today's SIP services. This book will help you * Work with SIP in Presence and event-based communications * Handle SIP-based application-level mobility issues * Develop applications to facilitate communications access for users with disabilities * Set up Internet-based emergency services * Explore how peer-to-peer SIP systems may change VoIP * Understand the critical importance of Internet transparency * Identify relevant standards and specifications * Handle potential quality-of-service and security problems

Book Description
Here is a thorough, not-overly-complex introduction to the three technical foundations for multimedia applications across the Internet: communications (principles, technologies and networking); compressive encoding of digital media; and Internet protocol and services. All the contributing systems elements are explained through descriptive text and numerous illustrative figures; the result is a book well-suited toward non-specialists, preferably with technical background, who need well-composed tutorial introductions to the three foundation areas. The text discusses the latest advances in digital audio and video encoding, optical and wireless communications technologies, high-speed access networks, and IP-based media streaming, all crucial enablers of the multimedia Internet.

Book Description
Just as the automobile radically changed people's lives at the beginning of the 20th century, so too has the revolution in online services (including blogging, podcasting, videogaming, shopping, and social networking) and cell-phone use changed our lives at the turn of the 21st century. In addition, many other services, activities, and devices—including the Palm Pilot, the BlackBerry, the iPod, digital cameras, and cell cameras—have been made possible by the combination of these two technologies. Whereas the automobile allowed people for the first time to work in cities and live comfortably in the suburbs, extending the long commute beyond the limits previously circumscribed by public transportation, the Internet and cell phone allow us to interact with others from around the world—or a few hundred miles—from where we work or live, giving rise to the telecommuting phenomenon and allowing us to stay in touch with friends and families in the new virtual environment. As Hanson demonstrates in her new book, these technologies enable us to work and play 24/7, anytime, anywhere. What does this mean for us as individuals and for society as a whole? What are the social implications of this technological revolution that we have witnessed in the short span of about 20 years? Do people of different generations use these technologies in the same ways, or do they adopt them to support their communication habits formed at different times of their lives? How does the illusion of control provided by these technologies affect the way we think about what is meaningful in our lives? Hanson examines the wide-ranging impact of this change. How do individuals posting their viewpoints on the Internet affect democracy? Is it possible to ever completely prevent identity theft over the Internet? How permanent is information stored on the Internet or on a hard drive? Do cell phones change the way people think about privacy or the way they communicate with others? Does email? Do videogames teach new social principles? Do cell phones and the Internet change traditional communication behaviors and attitudes? Hanson discusses these crucial issues and explores to what extent individuals do have control, and she assesses how social and governmental services are responding to (or running from) the problems posed by these new technologies.
