The dataset comprises physical-layer data measurements (I-Q samples) collected using an ADALM Pluto SDR version B. The original firmware from Analog Devices was replaced with the Maia-SDR Firmware (https://maia-sdr.org/). The data was gathered within a 250 square meter area of the WIRID-LAB (https://wirid-lab.umng.edu.co/ laboratory at the Military University Nueva Granada. The dataset is divided into two groups of measurements labeled 'JAMMER' and 'NORMAL', each containing 165 files. These files represent data collected from 15 different points across 11 WiFi channels. NORMAL Group: Measurements were taken under standard WiFi traffic conditions without any interference from a jammer. JAMMER Group: Measurements were taken while deploying a Legacy Short Training Field Jammer attack from a static point. Each .zip compressed file contains data for 15 measurement points, with each point captured over one second at a sampling rate of 15 Msps. The data is formatted according to the Signal Metadata Format (SigMF), with each measurement point having one .sigmf-data file and one .sigmf-meta file. File names indicate the WiFi channel (enumerated from 1 to 11), signal type (Jammer or Normal), and the attacker node's position 'P2'.
