DOWNLOAD EBOOKThere is widespread concern in the telecommunications industry that public policy may be impeding the continued development of the Internet into a high-speed communications network. In the absence of ubiquitous, high-speed ¡°broadband¡± Internet connections for residential and small-business customers, the demand for IT equipment and new Internet service applications may stagnate. Broadband policy is controversial in large part because of the differences in the regulatory regimes faced by different types of carriers. Cable television companies face neither retail price regulation of their cable modem services nor any requirements to make their facilities available to competitors. Local telephone companies, on the other hand, face both retail price regulation for their DSL service and a requirement imposed by the 1996 Telecommunications Act that they ¡°unbundle¡± their network facilities and lease them to rivals. Finally, new entrants are largely unregulated, but many rely on facilities leased from the incumbent telephone companies at regulated rates to connect to their customers. This asymmetric regulation is the focus of this volume, in which telecommunications scholars address the public policy issues that have arisen over the deployment of new high-speed telecommunications services. Robert W. Crandall is a senior fellow in the Economic Studies program at the Brookings Institution. His previous books include (with Martin Cave) Telecommunications Liberalization on Two Sides of the Atlantic (2001) and (with Leonard Waverman) Who Pays for Universal Service? (Brookings 2000). James H. Alleman is an associate professor in interdisciplinary telecommunications at the College of Engineering and Applied Science, University of Colorado, on leave at Columbia University.

DOWNLOAD EBOOKAn 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.

DOWNLOAD EBOOKService providers are increasingly focused on delivering triple-play bundles that incorporate Internet, video, and VoIP services—as well as multi-play bundles containing even more advanced services. Broadband Network Architectures is the first comprehensive guide to designing, implementing, and managing the networks that make triple-play services possible. Hellberg, Greene, and Boyes present their field-tested industry best practices and objectively evaluate the tradeoffs associated with key up-front architectural decisions that balance the complexities of bundled services and sophisticated traffic policies. Broadband Network Architectures not only documents what is possible on this rapidly changing field of networking, but it also details how to divide Internet access into these more sophisticated services with specialized Quality of Service handling. Coverage includes · An in-depth introduction to next-generation triple-play services: components, integration, and business connectivity · Triple-play backbone design: MPLS, Layer 3 VPNs, and Broadband Network Gateways (BNGs)/Broadband Remote Access Servers (B-RAS) · Protocols and strategies for integrating BNGs into robust triple-play networks · Triple-play access network design: DSLAM architectures, aggregation networks, transport, and Layer 2 tunneling · VLAN-per-customer versus service-per-VLAN architectures: advantages and disadvantages · PPP or DHCP: choosing the right access protocol · Issues associated with operating in wholesale, unbundled environments · IP addressing and subscriber session management · Broadband network security, including Denial of Service attacks and VoIP privacy · The future of wireless broadband: IMS, SIP, and non-SIP based fixed mobile convergence and wireless video

DOWNLOAD EBOOKThe 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.

DOWNLOAD EBOOKTen years ago, the United States stood at the forefront of the Internet revolution. With some of the fastest speeds and lowest prices in the world for high-speed Internet access, the nation was poised to be the global leader in the new knowledge-based economy. Today that global competitive advantage has all but vanished because of a series of government decisions and resulting monopolies that have allowed dozens of countries, including Japan and South Korea, to pass us in both speed and price of broadband. This steady slide backward not only deprives consumers of vital services needed in a competitive employment and business market—it also threatens the economic future of the nation. This important book by leading telecommunications policy expert Susan Crawford explores why Americans are now paying much more but getting much less when it comes to high-speed Internet access. Using the 2011 merger between Comcast and NBC Universal as a lens, Crawford examines how we have created the biggest monopoly since the breakup of Standard Oil a century ago. In the clearest terms, this book explores how telecommunications monopolies have affected the daily lives of consumers and America's global economic standing.
