Question on the CSI Tool settings

[EvCong24601]

Thanks for your data. I have a few questions on settings of the CSI tool
First, what is the exact centre frequency for 2.4Ghz and 5Ghz since each band has multiple channels.
For example, channel 44 is about 5.25Ghz.
Second, since Intel5300 NIC has three antennas , for each antennas which channel it works on.
For example ,the collected data has 181 columns. Data from 1 to 90 are assigned to three antennas. 1 to 30 is antenna one that works on 2.4Ghz

I am looking forward to your reply.
