Broadband Access

High-speed Internet access: the definitive "how-to" guide! Covers cable, DSL, and next-generation wireless high-speed Internet connections, this handbook also Includes Windows, MacOS and Linux coverage.

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.

Written by experts in the field, this book provides an overview of all forms of broadband subscriber access networks and technology, including fiber optics, DSL for phone lines, DOCSIS for coax, power line carrier, and wireless. Each technology is described in depth, with a discussion of key concepts, historical development, and industry standards. The book contains comprehensive coverage of all broadband access technologies, with a section each devoted to fiber-based technologies, non-fiber wired technologies, and wireless technologies. The four co-authors’ breadth of knowledge is featured in the chapters comparing the relative strengths, weaknesses, and prognosis for the competing technologies. Key Features: Covers the physical and medium access layers (OSI Layer 1 and 2), with emphasis on access transmission technology Compares and contrasts all recent and emerging wired and wireless standards for broadband access in a single reference Illustrates the technology that is currently being deployed by network providers, and also the technology that has recently been or will soon be standardized for deployment in the coming years, including vectoring, wavelength division multiple access, CDMA, OFDMA, and MIMO Contains detailed discussion on the following standards: 10G-EPON, G-PON, XG-PON, VDSL2, DOCSIS 3.0, DOCSIS Protocol over EPON, power line carrier, IEEE 802.11 WLAN/WiFi, UMTS/HSPA, LTE, and LTE-Advanced

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.

Several trends are hastening the use of MPLS-based VPNs in broadband networks. With this rapid evolution, networking professionals need resources like this new volume.

The internet has become so widespread that such issues as access, regulation and related policies have become major factors in the economy and social fabric of societies in every part of the world. Peoples without running water are demanding access to the internet and those without it are becoming deprived citizens. This new book examines current issues of interest to the blossoming area.

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.

Presents a thorough quantitative reasoning and analysis of HFC system technologies, including subcarrier multiplexed lightwave transmission systems and components, radio frequency modems for digital signals, and medium-access control protocols proposed by important standards bodies. Eleven chapters

Designed from the ground up with a constructivist framework, BUILDING TEACHERS: A CONSTRUCTIVIST APPROACH TO INTRODUCING EDUCATION, 2nd Edition helps future teachers create their own understanding of education. As the authors address the key topics generally covered in an introductory book, they encourage readers to develop their own understandings by connecting their prior knowledge, experiences, and biases with new experiences to which they will be exposed during the course. Highlights of the new edition include stronger standards integration and expanded material on diversity and technology. By interacting with the materials presented, rather than merely memorizing the book's content, readers learn what teaching is all about in an exploratory, inquiring, constructivist-based manner. In turn, they can help the children in their classrooms learn meaningfully. Available with InfoTrac Student Collections http://gocengage.com/infotrac.
