The contributors to Signal Traffic investigate how the material artifacts of media infrastructure--transoceanic cables, mobile telephone towers, Internet data centers, and the like--intersect with ...everyday life. Essayists confront the multiple and hybrid forms networks take, the different ways networks are imagined and engaged with by publics around the world, their local effects, and what human beings experience when a network fails. Some contributors explore the physical objects and industrial relations that make up an infrastructure. Others venture into the marginalized communities orphaned from the knowledge economies, technological literacies, and epistemological questions linked to infrastructural formation and use. The wide-ranging insights delineate the oft-ignored contrasts between industrialized and developing regions, rich and poor areas, and urban and rural settings, bringing technological differences into focus. Contributors include Charles R. Acland, Paul Dourish, Sarah Harris, Jennifer Holt and Patrick Vonderau, Shannon Mattern, Toby Miller, Lisa Parks, Christian Sandvig, Nicole Starosielski, Jonathan Sterne, and Helga Tawil-Souri.

The Internet has reached a critical point. The world is running out of Internet addresses. There is a finite supply of approximately 4.3 billion Internet Protocol (IP) addresses--the unique binary ...numbers required for every exchange of information over the Internet--within the Internet's prevailing technical architecture (IPv4). In the 1990s the Internet standards community selected a new protocol (IPv6) that would expand the number of Internet addresses exponentially--to 340 undecillion addresses. Despite a decade of predictions about imminent global conversion, IPv6 adoption has barely begun.Protocol Politicsexamines what's at stake politically, economically, and technically in the selection and adoption of a new Internet protocol. Laura DeNardis's key insight is that protocols are political. IPv6 intersects with provocative topics including Internet civil liberties, US military objectives, globalization, institutional power struggles, and the promise of global democratic freedoms. DeNardis offers recommendations for Internet standards governance, based not only on technical concerns but on principles of openness and transparency, and examines the global implications of looming Internet address scarcity versus the slow deployment of the new protocol designed to solve this problem.
The shift from manufacturing- to service-based economies has often been accompanied by the expansion of low-wage and insecure employment. Many consider the effects of this shift inevitable. ...InDisintegrating Democracy at Work, Virginia Doellgast contends that high pay and good working conditions are possible even for marginal service jobs. This outcome, however, depends on strong unions and encompassing collective bargaining institutions, which are necessary to give workers a voice in the decisions that affect the design of their jobs and the distribution of productivity gains.
Doellgast's conclusions are based on a comparative study of the changes that occurred in the organization of call center jobs in the United States and Germany following the liberalization of telecommunications markets. Based on survey data and interviews with workers, managers, and union representatives, she found that German managers more often took the "high road" than those in the United States, investing in skills and giving employees more control over their work. Doellgast traces the difference to stronger institutional supports for workplace democracy in Germany. However, these democratic structures were increasingly precarious, as managers in both countries used outsourcing strategies to move jobs to workplaces with lower pay and weaker or no union representation. Doellgast's comparative findings show the importance of policy choices in closing off these escape routes, promoting broad access to good jobs in expanding service industries.
The 1996 Telecommunications Act was an attempt to increase competition among telecommunications providers in the United States by reducing regulatory barriers to market entry. This competition was ...expected to drive innovation in the telecommunications sector and reap economic benefits for both American consumers and telecommunications providers. The legislation, however, had a markedly different impact. While many of the more aggressive providers enjoyed sharp short-term rises in stock market values, they soon faced sudden collapse, leaving consumers with little or no long-term benefit.
InCompetition and Chaos, Robert W. Crandall analyzes the impact of the 1996 act on economic welfare in the United States and how the act and its antecedents affected the major telecommunications providers. He argues that the act was far too stringent, inviting the Federal Communications Commission and state regulators to micromanage competitive entry into local telecommunications markets. Combined with the bursting of the dot.com and telecom stock market bubbles, this aggressive policy invited new and existing firms to invest billions of dollars unwisely, leading to the 2001-02 collapse of equity values throughout the sector. New entrants into the market invested more than $50 billion in unproductive assets that were quickly wiped out through massive failures. The 1996 act allowed the independent long-distance companies, such as MCI and AT& T, to live a few years longer. But today they are a threatened species, caught in a downward spiral of declining prices and substantial losses. The industry is preparing for an intense battle for market share among three sets of carriers: the wireless companies, the local telephone carriers, and the cable television businesses. Each has its own particular advantage in one of the three major segments of the market -voice, data, and video -but none is assured a clear path to dominance. Although the telecom stock market collapse is now history and the survivors are investing once again, Crandall concludes that the regulators have failed to adapt to the chaos to which they contributed.

China's telecommunications industry has seen revolutionary transformation and growth over the past three decades. Chinese Internet users number nearly 150 million, and the PRC expects to quickly pass ...the US in total numbers of connected citizens. The number of mobile and fixed-line telephone users soared from a mere 2 million in 1980 to a total of nearly 800 million in 2007. China has been the most successful developing nation in history for spreading telecommunications access at an unparalleled rapid pace. This book tells how China conducted its remarkable "telecommunications revolution". It examines both corporate and government policy to get citizens connected to both voice and data networks, looks at the potential challenges to the one-party government when citizens get this access, and considers the new opportunities for networking now offered to the people of one of the world's fastest growing economies. The book is based on the author's fieldwork conducted in several Chinese cities, as well as extensive archival research. It focuses on key issues such as building and running the country's Internet, mobile phone company rivalry, foreign investment in the sector, and telecommunications in China's vibrant city of Shanghai. It also considers the country's internal "digital divide", and questions how equitable the telecommunications revolution has been. Finally, it examines the ways the PRC's entry to the World Trade Organization will shape the future course of telecommunications growth.

Ten 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.
