Abstract
Technologies directed to channel state information (CSI) sending in the 2.4 GHz band are described. A method includes receiving first CSI data representing channel properties of a first wireless channel used by first and wireless devices that operates in the 2.4 GHz band. The method receives second and third CSI data corresponding to second and third wireless channels. The method determines an inference probability of a motion or a non-motion condition in the geographical region based on an average probability of CSI samples from the first, second, and third CSI data.
