Falling Through the Net: Defining the Digital Divide -- HTML version

A Nation Online: How Americans Are Expanding Their Use of the Internet provides an insightful look at how Americans are increasing their connectivity to information technologies.  We are fortunate to be able to base our findings on the September 2001 U.S. Census Bureau’s Current Population Survey – a survey of approximately 57,000 households and more than 137,000 individuals across the United States.  As such, the data in this study are among the most broad-based and reliable datasets that have been gathered on Internet, broadband, and computer connectivity.

A Nation Online: How Americans Are Expanding Their Use of the Internet is available in two formats:

• HTML
• PDF
• For the convenience of researchers, the charts detailing percentages of U.S. households with a computer and with Internet access are posted separately.
• The Census Bureau’s Survey Instrument and Raw Data is available at https://www.census.gov

This report highlights the dramatic growth of broadband in the United States.  The report shows that the Administration’s technology, regulatory and fiscal policies have stimulated innovation and competition, and encouraged investment in the U.S. broadband market contributing to significantly increased accessibility of broadband services.

Pursuant to Section 6001(d)(4) of the American Recovery and Reinvestment Act of 2009 (Recovery Act or Act) (Public Law No. 111-5), the National Telecommunications and Information Administration (NTIA) provides this quarterly report on the status of the Broadband Technology Opportunities Program (BTOP).

The National Telecommunications and Information Administration (NTIA), an agency of the U.S. Department of Commerce, is responsible for managing federal agency use of the radio spectrum. The NTIA establishes policies concerning frequency assignment, allocation and use, and provides the various federal departments and agencies with guidance to ensure that their conduct of telecommunications activities is consistent with these policies. The NTIA also serves under the Executive Branch as the President's principal adviser on telecommunication policies pertaining to the nation's economic and technological advancements and to the regulation of the telecommunications industry.

The purpose of this handbook is to provide the radio frequency (RF) analyst with the capability to calculate the effects of noise and interference on RF communications receivers. A receiver is modeled as a sequence of modules. Each module has a transfer function that relates the module outputs to the module inputs. By consecutively analyzing each module in the sequence, the analyst can then relate the receiver outputs (performance) to the receiver inputs (signal characteristics).
