Over the next five to 10 years, wireless technologies will dramatically reshape the communications and information infrastructure of the United States. New radio-based systems now being developed will use advanced digital technologies to bring a wide array of services to both residential and business users, including ubiquitous mobile telephone and data services and many new forms of video programming. Existing wireless systems, including radio and television broadcasting, cellular telephony, and various satellite and data networks, will also convert to digital technology. This will allow them to improve the quality of their services, expand the number of users they can serve, and offer new information and entertainment applications. Before the benefits of these wireless systems can be realized, however, technical, regulatory, and economic uncertainties must be resolved. This report examines the role wireless communication technologies will play in the evolving National Information Infrastructure (NII), examines the challenges facing policy-makers and regulators as wireless becomes a more integral part of the telecommunications and information infrastructure, and identifies some of the longer term implications of the widespread use of wireless systems and services.
In a post–Cold War world, the Iridium satellite network revealed a new age of globalization. Winner of the William and Joyce Middleton Electrical Engineering History Award by the IEEE In June 1990, Motorola publicly announced an ambitious business venture called Iridium. The project’s signature feature was a constellation of 77 satellites in low-Earth orbit which served as the equivalent of cellular towers, connecting to mobile customers below using wireless hand-held phones. As one of the founding engineers noted, the constellation “bathed the planet in radiation,” enabling a completely global communications system. Focusing on the Iridium venture, this book explores the story of globalization at a crucial period in US and international history. As the Cold War waned, corporations and nations reoriented toward a new global order in which markets, neoliberal ideology, and the ideal of a borderless world predominated. As a planetary-scale technological system, the project became emblematic of this shift and of the role of the United States as geopolitical superpower. In its ambition, scope, challenges, and organizing ideas, the rise of Iridium provides telling insight into how this new global condition stimulated a re-thinking of corporate practices—on the factory floor, in culture and knowledge, and in international relations. Combining oral history interviews with research in corporate records, Martin Collins opens up new angles on what global meant in the years just before and after the end of the Cold War. The first book to tell the story of Iridium in this context, A Telephone for the World is a fascinating look at how people, nations, and corporations across the world grappled in different ways with the meaning of a new historical era.
The field of microwave engineering has undergone a radical transformation in recent years, as commercial wireless endeavors overtook defense and government work. The modern microwave and RF engineer must be knowledgeable about customer expectations, market trends, manufacturing technologies, and factory models to a degree that is unprecedented. Unf

Ironically, the technology that has made possible so many exciting astronomical discoveries is now jeopardizing the future of observational astronomy. The effects of atmospheric degradation, electromagnetic pollution, and near-Earth space debris are taking their toll. This provocative survey convincingly demonstrates the destructive impact of civilization on current observational astronomy. International astronomers discuss the sources and effects of environmental pollution and degradation and together with specialists from industry, law and elsewhere, they outline possible remedies and the legislation required for successful international regulation of the pollutants. These articles provide essential reference for the professional astronomer, environmentalist, and concerned nonspecialist.
