Considering the key evolutions within the access network technologies as well as the unprecedented levels of bandwidth demands by end users, this book condenses the relentless research, design, and deployment experience of state-of-the-art access networks. Furthermore, it shares the critical steps and details of the developments and deployment of these emergent technologies; which is very crucial particularly as telecommunications vendors and carriers are looking for cost-effective ultra-broadband “last-mile” access solutions to stay competitive in the “post bubble” era. The book is written to provide a comprehensive overview of the major broadband access technologies and deployments involving internationally recognized authors and key players. Due to its scope and depth, the proposed book is able to fill an important gap of today’s available literature.
The access network is expected to be one of the major battlegrounds of telecommunications network operators, since upgrades of the existing narrowband access network will be the critical factor in supplying multimedia broadband services in a competitive market. The future broadband access network architecture needs to be flexible enough to efficiently support the provision of a full set of broadband and narrowband services with a wide range of capacity demands. A wide range of broadband access technologies are available. Furthermore, the key issues in the upgrading of the very cost sensitive access network are financial as well as technological, both for incumbent and new entrant operators. Thus, in order to identify minimum-risk introductory strategies the economic viability of access network broadband upgrades needs to be carefully assessed. However, despite the definite need for techno-economic evaluations, very few books have been published in this field. One of the reasons might be that broadband access network upgrading only very recently gained wide recognition as a key challenge for broadband delivery. Secondly, this kind of strategic work and these studies tend to be considered rather sensitive by operators, and thus both results and methodologies are not usually readily available. Thirdly, the work reported in this book in many respects was a major pioneering effort, which quite ambitiously aimed at modelling the whole life-cycle costs and revenue streams of access network upgrades, as opposed to several other efforts, which often are limited to pure investment cost comparisons.

The OECD Digital Economy Outlook examines and documents the evolutions and emerging opportunities and challenges in the digital economy. It highlights how OECD countries and partner economies are taking advantage of ICTs and the Internet to meet their public policy objectives.
Here's an authoritative, cutting-edge resource that gives you a thorough understanding of CDMA transmission and detection. It offers practical guidance in designing interference-reducing multi-user receivers for mobile radio systems and multi-user adaptive modems for accessing satellite earth stations. The book provides in-depth descriptions of CDMA principles, and of linear and non-linear multi-user detection, and covers the fine details of the realization of a linear multi-user receiver. Extensively supported with over 565 equations and more than 95 illustrations, the book enables you to devise accurate system models of both a cellular TD-CDMA radio interface and an asynchronous satellite radio interface. It allows you to choose among different architectural solutions for both linear multi-user receivers to be operated in TD-CDMA radio systems and adaptive linear CDMA receivers in satellite asynchronous CDMA systems.
After broadband access, what next? What role do metrics play in understanding “information societies”? And, more important, in shaping their policies? Beyond counting people with broadband access, how can economic and social metrics inform broadband policies, help evaluate their outcomes, and create useful models for achieving national goals? This timely volume not only examines the traditional questions about broadband, like availability and access, but also explores and evaluates new metrics more applicable to the evolving technologies of information access. Beyond Broadband Access brings together a stellar array of media policy scholars from a wide range of disciplines—economics, law, policy studies, computer science, information science, and communications studies. Importantly, it provides a well-rounded, international perspective on theoretical approaches to databased communications policymaking in the Americas, Europe, Asia, and Africa. Showcasing a diversity of approaches, this invaluable collection helps to meet myriad challenges to improving the foundations for communications policy development.
Access to the Internet is an increasing problem in many areas of the world. As the popularity and usefulness of the Internet increases on a daily basis, lack of access to the technology is putting many groups at a disadvantage in terms of better education, better jobs and even in terms of higher levels of civic participation. However, creating a network infrastructure to serve outlying communities and sectors of the population is not straight-forward. This book brings together all the aspects of the problem – technical, regulatory and economic - into one volume to provide a comprehensive resource. It describes the latest technological advances that allow cost-effective network infrastructures to be built, and places them in the context of the applications and services that the infrastructure will deliver. A section on business models and case studies from North American and Europe demonstrate that the solutions are economically and practically viable. This book is essential for anyone looking to gain an understanding of the issues and technology surrounding the access debate. It will be of particular relevance to network engineers/designers/planners at the incumbent operator companies charged with delivering broadband access to as yet unconnected regions. Governments and regulatory bodies will also find this a useful guide to the problems that they may face.
An analysis of the failure of U.S. broadband policy to solve the rural–urban digital divide, with a proposal for a new national rural broadband plan. As much of daily life migrates online, broadband—high-speed internet connectivity—has become a necessity. The widespread lack of broadband in rural America has created a stark urban–rural digital divide. In Farm Fresh Broadband, Christopher Ali analyzes the promise and the failure of national rural broadband policy in the United States and proposes a new national broadband plan. He examines how broadband policies are enacted and implemented, explores business models for broadband providers, surveys the technologies of rural broadband, and offers case studies of broadband use in the rural Midwest. Ali argues that rural broadband policy is both broken and incomplete: broken because it lacks coordinated federal leadership and incomplete because it fails to recognize the important roles of communities, cooperatives, and local providers in broadband access. For example, existing policies favor large telecommunication companies, crowding out smaller, nimbler providers. Lack of competition drives prices up—rural broadband can cost 37 percent more than urban broadband. The federal government subsidizes rural broadband by approximately $6 billion. Where does the money go? Ali proposes democratizing policy architecture for rural broadband, modeling it after the wiring of rural America for electricity and telephony. Subsidies should be equalized, not just going to big companies. The result would be a multistakeholder system, guided by thoughtful public policy and funded by public and private support.
The Internet has enabled the convergence of all things information-related.
