Wi-Fi and Bluetooth I/Q Recordings in the 2.4 GHz and 5 GHz Bands with Low-Cost Software Defined Radios

Data provided by  National Institute of Standards and Technology

This dataset consists of baseband in-phase/quadrature (I/Q) radio frequency recordings of Wi-Fi and Bluetooth radiated emissions in the 2.4 GHz and 5 GHz unlicensed bands collected with low-cost software defined radios. A NIST technical note describing the data collection methods is pending publication. All I/Q captures are one second in duration, with a sampling rate of 30 mega samples per second (MS/s), and a center frequency of 2437 MHz for the 2.4 GHz band captures and 5825 MHz for the 5 GHz band captures.

2020 Annual Business Survey: Company Summary

Data provided by  United States Census Bureau

The Annual Business Survey (ABS) provides information on selected economic and demographic characteristics for businesses and business owners by sex, ethnicity, race, and veteran status. Further, the survey measures research and development (for microbusinesses), new business topics such as innovation and technology, as well as other business characteristics. The U.S. Census Bureau and the National Center conduct the ABS jointly for Science and Engineering Statistics within the National Science Foundation.

NIST Fingerprint Registration and Comparison Tool (NFRaCT)

Data provided by  National Institute of Standards and Technology

The NIST Fingerprint Registration and Comparison Tool (NFRaCT) is a cross-platform GUI application which allows a user to load a pair of fingerprint images, find corresponding points in both images, register and crop the images, and finally compute a series of measurements on the registered images as described in NIST Special Publication 500-336

Thermodynamic Data from Unpublished Sources to Support the New Reference Equation of State for Carbon Dioxide

Data provided by  National Institute of Standards and Technology

During work on the new reference equation of state for carbon dioxide [E.W. Lemmon, A.H. Harvey, and R. Hellmann, NIST Internal Report, to be published in 2025], we obtained unpublished data from several sources. These represent numerical values for data only presented graphically in a publication, or in some cases data not present in the publication at all. With the permission of the authors, we document and deposit these data here so they will be available for future workers.
