CSI Dataset espargos-0005: Four phase- and time-synchronous ESPARGOS antenna arrays in a lab room

<p>Dataset containing WiFi channel state information (CSI) alongside ground truth data (position tags, timestamps) measured with ESPARGOS antenna arrays. Measurement parameters and machine-readable file format descriptions are provided in a JSON file (spec.json).</p>

Four ESPARGOS arrays are placed in the corners of a lab room. Even though they are distributed in space, they are synchronized in both time and phase thanks to wired clock / phase distribution.
