Distributed Sensing of Radio Spectrum Occupancy Amid COVID-19

Data provided by  National Institute of Standards and Technology

During the COVID-19 pandemic, National Institute of Standards and Technology (NIST) performed a targeted campaign of measurements of channel power and occupancy rate in the radio spectrum. This is the dataset that resulted from that effort.Measurements were performed in 13 residential sites after a rapid engineering development effort, followed by spot measurements at a local hospital. The study targeted radio frequency allocations that support key wireless data infrastructure.

Measurements of IP3 and P1dB for Spectrum Monitoring with Software Defined Radios (Public Release of Data)

Data provided by  National Institute of Standards and Technology

These data were acquired in the process of collecting data for [1]. They comprise IQ waveform outputs of two different software-defined radios (SDRs) that were collected for various combinations of 1- and 2-tone excitation conditions. For details about how the data were collected, see that publication. [1] McNulty, M., Gu, D., Kuester, D. and Nayeri, P.

SCAP Composer

Data provided by  National Institute of Standards and Technology

SCAP Composer is a software application for creating Security Content Automation Protocol (SCAP) source data stream collections from Extensible Markup Language (XML) documents valid with respect to schemas defined in SCAP component specifications. SCAP Composer's limited scope and small footprint make it easy to install, use, and integrate with other SCAP content development tools. SCAP Composer uses the DITA Open Toolkit, an open source publishing engine for content authored in the Darwin Information Typing Architecture (DITA).
