This dataset contains IQ-baseband recordings of data frames transmitted from a Lenovo Thinkpad T470s. A program called Scapy was used to force the WLAN chip (Intel 8265NGW) of the laptop to send a data frame with a fixed bit payload on repeat. The measurements were conducted in the anechoic chamber located at the Tampere University's Hervanta campus. The dataset contains 10 repeat recordings with MCS indices 3,5,6 and 8. The WLAN bandwidth was 20 MHz on channel 12, corresponding to center frequency of 2.467 GHz. The recordings were made with a vector signal transceiver PXIe-5840 by National Instruments. The sampling frequency in all recordings was 200 MHz with a recording length of 20e6 samples, corresponding to a recording period of 100 ms. All recordings are provided in a binary format. More specifically, the data is interleaved (I1 Q1 I2 Q2 I3 Q3 ...) in little-endian 64-bit floating point format. A matlab function is provided for converting the binary data in a file to a complex float vector. Additionally, a simple Matlab example script is provided to showcase how the data can be used to plot a spectrogram.
