This paper proposes a technique to recognize human motion and distinguish people using CSI, a big data analysis technique. CSI is used to develop MIMO technology. We measure the waveform of the subcarriers that are exchanged during communication between WiFi devices, and create CSI information, which is then used as an input for a big data algorithm and provides device-free based information that can extract characteristic information about repeated human behavior. We propose a technique to… CONTINUE READING
