On the number of dimensions of the CSI data obtained with this tool

[ghost]

Excuse me for asking.
I believe that other CSI acquisition tools can acquire CSI data in the dimension multiplied by the number of receiving antennas, transmitting antennas, and subcarriers.
For example, in the case of 2 receiving antennas, 2 transmitting antennas, and 30 subcarriers
2 * 2 * 30 = 120
Thus, we think we can get 120 dimensions of data.
Is it possible to increase or decrease the number of transmitting and receiving antennas to increase the number of dimensions that can be acquired with this tool?
