Broadband: Bringing Home the Bits http://www.nap.edu/catalog/10235.html National Academy of Sciences National Academy of Engineering Institute of Medicine National Research Council The National Academy of Sciences is a private, nonprofit, self-perpetuating soci- ety of distinguished scholars engaged in scientific and engineering research, dedi- cated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Bruce M. Alberts is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its mem- bers, sharing with the National Academy of Sciences the responsibility for advis- ing the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Wm. A. Wulf is president of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Kenneth I. Shine is president of the Institute of Medicine. The National Research Council was organized by the National Academy of Sci- ences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal gov- ernment. Functioning in accordance with general policies determined by the Acad- emy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering commu- nities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Bruce M. Alberts and Dr. Wm. A. Wulf are chairman and vice chairman, respectively, of the National Research Council. Copyright © National Academy of Sciences. All rights reserved.

Broadband: Bringing Home the Bits http://www.nap.edu/catalog/10235.html Preface Since its inception, the Computer Science and Telecommunications Board (CSTB) has examined how the nation’s networked infrastructure has been evolving. At the close of the past decade, the popular appeal of the Internet was evident and growing, and with it the range and richness of the uses to which the Internet might be put. The vision of a popular Internet leads inevitably to thoughts about how people use it in their homes—and then to the arresting observation that most people get the best possible access to the Internet from outside their homes, if they can get it at all. That observation led CSTB to frame an assessment

    Finding Patterns and Making Predictions: A Dialogue on Mentored Student Research and Engaged Learning Abroad Anthony Hatcher, Ph.D., Elon University, US, [email protected] Mia Watkins, A.B., Elon University, US During the week of April 7-11, 2014, a team of five undergraduate researchers and two mentors from Elon University in Elon, N.C., traveled to Hong Kong to conduct oral history interviews with inductees at the Internet Hall of Fame (IHOF) Induction/International IT Fest 2014. Coverage of IHOF is one of the many joint initiatives of the Pew Research Center’s Internet & American Life Project and the Imagining the Internet Center at Elon University. This essay presents an overview of the planning and research processes used by Elon University School of Communications students who interviewed and recorded inductees to the 2014 Internet Hall of Fame. The essay concludes with a dialogue between a professor/mentor, Anthony Hatcher, and one of the student researchers, Mia Watkins, who conducted follow-up research based on the interviewees’ responses. Watkins’ commentary on various stages of the process also appears throughout the essay. About the Imagining the Internet Center A central purpose of Elon’s Imagining the Internet Center is primary source data collection in order to create a permanent, ongoing archive and interactive history of the rapidly evolving world of digital communication, specifically the origins and development of the Internet. These data include video interviews with Internet pioneers involved in significant discoveries and innovations. The Center maintains that learning from past achievements can inform future public policy. The mission of the Imagining the Internet Center is “to explore and provide insights into emerging network innovations, global development, dynamics, diffusion and governance” (Imagining the Internet, n.d.).

    New ECE Building Design Approved

    NEWS FOR ECE ILLINOIS ALUMNI AND FRIENDS FALL 2010 New ECE building design approved Also in this issue: The cell whisperers Levinson works to create artificially intelligent robots Boppart receives NIH grant to study mechanics of cancerous cells Seeing the world as a photograph Department of Electrical and Computer Engineering Creating a hearth and home Dear alumni, I think you will find this to be an exciting issue as we share some of the newest developments of our ECE building campaign. In addition to an update of the latest information on the building, we have an interview with David King, the lead architect on the project, and some information on how our alumni can become more involved in the campaign. As I contemplate what the new building will mean for our ECE community, the origins of the ancient Greek concept of the hearth come to mind. Hestia. In ancient Greece, Hestia was the goddess of the sacred fire and was considered the most important of the goddesses. The daily tribute to this goddess was simple, to keep the hearth alive, burning with warmth and all the promise of fire. The word also means “focus,” both a point of convergence and a point of departure. As we stand at the threshold of embarking on the revitalization of ECE with the construction of the new home building for our department, the anticipation of one central hearth—to shelter, to welcome, and to inspire—validates our endeavor. As members of the ECE ILLINOIS family, we know the entity of our vibrant engineering community is sustained by us, wherever we are, because we cannot circumscribe the reach and impact of ECE ILLINOIS within the confines of a building.

The research examines the outcome starting with events in 1960s when broadband as it is defined today did not exist. The research shows that a combination of factors involving regulatory decisions, changing market conditions, and unexpected technological breakthroughs contributed to the current day mix of broadband technologies in the last mile access in the UK. To interpret the events that have shaped the development, deployment, and adoption of broadband technologies in the UK, the thesis draws from various theoretical ideas related to Science and Technology Studies (STS) to understand and analyse the events.
