    Potential markets for advanced satellite communications

    This report identifies trends in the volume and type of traffic offered to the U.S. domestic communications infrastructure and extrapolates these trends through the year 2011. To describe how telecommunications service providers are adapting to the identified trends, this report assesses the status, plans, and capacity of the domestic communications infrastructure. Cable, satellite, and radio components of the infrastructure are examined separately. The report also assesses the following major applications making use of the infrastructure: (1) Broadband services, including Broadband Integrated Services Digital Network (BISDN), Switched Multimegabit Data Service (SMDS), and frame relay; (2) mobile services, including voice, location, and paging; (3) Very Small Aperture Terminals (VSAT), including mesh VSAT; and (4) Direct Broadcast Satellite (DBS) for audio and video. The report associates satellite implementation of specific applications with market segments appropriate to their features and capabilities. The volume and dollar value of these market segments are estimated. For the satellite applications able to address the needs of significant market segments, the report also examines the potential of each satellite-based application to capture business from alternative technologies

    When to broadcast intentions and when to exploit relationships: Information sharing strategies in the second generation wireless standards contest

    This study offers a new approach to understanding the diffusion of a new technology; specifically on the process of information sharing and its influence on a market based standards contest. Since diffusion relies upon adopting firms to gather information and learn about a new technology prior to adoption, communication of a technology's attributes and benefits is essential to the overall process of diffusion. The flow of information from sponsors to adopters is an influential action that serves to impact both the speed and degree of adoption of a new technology and can influence the outcome of market based standards contest. I explore these issues through a case analysis of the wireless phone industry and the 2G standards contest in the United States by studying the information sharing actions and events of two technology sponsors; Ericsson and Qualcomm. I develop a model of information sharing that identifies how aspects of timing, message, media, and target of influence combine to form two primary types of information sharing; cascade and broadcast. This model draws on concepts from the relevant body of literature on standards contests, social networks and communication theories

    Future benefits and applications of intelligent on-board processing to VSAT services

    Get PDF
    The trends and roles of VSAT services in the year 2010 time frame are examined based on an overall network and service model for that period. An estimate of the VSAT traffic is then made and the service and general network requirements are identified. In order to accommodate these traffic needs, four satellite VSAT architectures based on the use of fixed or scanning multibeam antennas in conjunction with IF switching or onboard regeneration and baseband processing are suggested. The performance of each of these architectures is assessed and the key enabling technologies are identified

    Campus Telecommunications Systems: Managing Change

    Get PDF
    The purpose of this book is to provide a broadbased understanding of the rapidly changing environment of campus telecommunications. The anticipated audience for this material is the non-technical university administrator who may not have direct responsibility for telecommunications, but has a need to understand the general environment in which his telecommunications manager functions and the basic concepts of the technology. Five topic areas were selected that best cover the preponderance of issues. No attempt has been made to associate or closely coordinate materials from one chapter\u27s subject to that of any other. Each chapter generally stands alone. In total, however, the five chapters address the topics and issues that most often generate inquiries from university administrators outside the telecommunications department.

    Toward a Unified Theory of Access to Local Telephone Systems

    One of the most distinctive developments in telecommunications policy over the past few decades has been the increasingly broad array of access requirements regulatory authorities have imposed on local telephone providers. In so doing, policymakers did not fully consider whether the justifications for regulating telecommunications remained valid. They also allowed each access regime to be governed by its own pricing methodology and set access prices in a way that treated each network component as if it existed in isolation. The result was a regulatory regime that was internally inconsistent, vulnerable to regulatory arbitrage, and unable to capture the interactions among network elements that give networks their distinctive character. In this Article, Professors Daniel Spulber and Christopher Yoo trace the development of these access regimes and evaluate the extent to which the emergence of competition among local telephone providers has undercut the rationales traditionally invoked to justify regulating local telephone networks (e.g., natural monopoly, network economic effects, vertical exclusion, and ruinous competition). They then apply a five-part framework for classifying different types of access that models the interactions among different network components. This framework demonstrates the impact of different types of access on network configuration, capacity, reliability, and cost. The framework also demonstrates how mandated access can increase transaction costs by forcing local telephone providers to externalize functions that would be more efficiently provided within the boundaries of the firm

    The Enduring Lessons of the Breakup of AT&T: A Twenty-Five Year Retrospective. \u27 Conference held at the University of Pennsylvania Law School on April 18-19, 2008. Over the past several decades, regulatory authorities have imposed an increasingly broad array of access requirements on local telephone providers. In so doing, policymakers typically applied previous approaches to access regulation without fully considering whether the regulatory justifications used in favor of those previous access requirements remained valid. They also allowed each access regime to be governed by a different pricing methodology and set access prices in a way that treated each network component as if it existed in isolation. The result was a regulatory regime that was internally inconsistent and vulnerable to regulatory arbitrage. In this Article, Professors Daniel Spulber and Christopher Yoo trace the development of these access regimes and evaluate the continuing validity of the rationales traditionally invoked to justify mandating access to local telephone networks (e.g., natural monopoly, network economic effects, vertical exclusion, and ruinous competition) in a world in which competition among local telephone providers is a real possibility. They then apply a five-part framework for classifying different types of access based on the branch of mathematics known as graph theory that models the interactions among different components. This framework shows how different types of access can have a differential impact on network configuration, capacity, reliability, and cost. It also captures the extent to which networks constitute complex systems in which network components interact with one another in ways that can make network behavior quite unpredictable. In addition, the framework demonstrates how mandated access can increase transaction costs by forcing local telephone providers to externalize functions that would be more efficiently provided within the boundaries of the firm
