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