Exploring the Digital Nation: America’s Emerging Online Experience
This report, based on data from the Census Bureau’s July 2011 Current Population Survey (“CPS”) Computer and Internet Use Supplement, updates and substantially expands on the previous study in this series, Exploring the Digital Nation: Computer and Internet Use at Home, issued in 2011. For the first time in eight years, this study goes beyond new findings on computer and Internet adoption in the United States to also present data on Americans’ online activities – what Americans do once they connect to the Internet.

Broadband Availability Beyond the Rural/Urban Divide
While it is commonly understood that broadband is less available in rural communities and more available in urban communities, a simple two-way, rural-urban comparison masks the fact that there is considerable variation in availability within these two types of communities. By assigning communities to one of five categories, it becomes clear that there is not a simple rural/urban divide. Rather, one group of rural Americans has even less broadband access than previously understood and two groups of urban Americans have more broadband than is typically identified.
Tabulations of Propagation Data over Irregular Terrrain in the 230-TO 9200-MHz Frequency Range Part IV: Receiver Site in Grove of Trees
This is the fourth part of a four-part report containing tabulations and graphs of transmission loss data resulting from propagation experiments in the 230 - to 9200-
MHz frequency range conducted over irregular terrain in Colorado. This part presents data obtained at a Common receiver site, located in a small grove of cottonwood
(Populus deltoides) trees, over propagation paths varying in length fro 0.5 to 50 km.
Key Words: UHF propagation data, irregular terrain, UHF

A Wave Hop Propagation Program for an Anisotropic Ionosphere
This report documents a digital computer program for computing the propagation of LF and VLF radio waves using the wave hop theory. It supersedes NBS Report 8889. The documentation includes a description of the physical model, detailed mathematical formulas, a main function flow chart, a listing of the FORTRAN source deck, and the input and output of a sample case.
