Abstract: Object movement detection may be provided. Channel State Information (CSI) data may be obtained. The CSI data may be associated with a plurality of links between a plurality of Access Points (APs) that provide coverage to an area. Next, a plurality of features may be extracted from the CSI data. The plurality of features may then be converted to a plurality of scores. Then motion in sub-areas of the area may be classified based on a comparison of the plurality of scores to a threshold for the area. The threshold may be determined based upon data collected when no motion occurred in the area.
