List of Public Datasets

Our datasets are collections of channel state information (CSI) measurements created with ESPARGOS for various interesting environments. With our datasets, you can benchmark your CSI-based algorithms without the hassle of setting up experiments and collecting data. Once your algorithms are verified to work on the datasets, you can easily switch over to a real-time implementation with actual ESPARGOS hardware.

ESPARGOS datasets build on extensive experience providing datasets with DICHASUS, which you may want to consider if you need even higher-quality CSI datasets.

Four phase- and time-synchronous ESPARGOS antenna arrays in a lab room

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.

Larger combined antenna array, indoor lab room with metal wall, LoS and NLoS areas

Four ESPARGOS arrays are combined into one large array with 8 by 4 antennas. A metal wall blocks the LoS path in parts of the measurement area. The wall is later removed.
