Product description
The ESPARGOS One Core Kit is a phase-coherent 2.4 GHz Wi-Fi measurement array designed for research, development and education. Eight phase-synchronized ESP32-based receiver channels capture Channel State Information (CSI) simultaneously across eight dual-polarized patch antennas.
This gives researchers access not only to received signal power but also to complex amplitude and phase information across OFDM subcarriers. ESPARGOS One is suitable for angle-of-arrival estimation, MUSIC spatial spectrum analysis, channel sounding, azimuth-delay studies, multipath analysis, antenna measurements and reproducible CSI datasets.
