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

Published by National Institute of Standards and Technology | National Institute of Standards and Technology | Catalog Last Checked: August 03, 2026 at 03:51 AM | Dataset Last Updated: August 04, 2022
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. In total, the data consist of 900 one second captures, organized into five Hierarchical Data Format 5 (HDF5) files, where each HDF5 file has a size of 20.1 GB and consists of 180 one second captures. There is a metadata file associated with each data file in comma-separated values (CSV) format that contains relevant parameters such as center frequency, bandwidth, sampling rate, bit depth, receive gain, antenna and hardware information. There are two additional CSV files containing estimated gain calibration and noise floor values.
