Hi,

I noticed that your team collected data with 1000 samples per second. could you explain how to achieve this ?

Thanks a lot.

The sample rate can achieved by changing the number of packets sent per second from the receiver. If you take a look at the csi tool, two mode can be used for receiving CSI: Monitor mode and AP mode. In monitor mode the 'random_packets' command is used to transmit packets and the rate can be set by changing its arguments. While in AP mode, the rate can be changed by simply pinging after particular intervals.
