Abstract: One embodiment provides a method for presence detection based on wireless signal analysis, the method comprising extracting features from wireless signals transmitted between a plurality of stations (STAs) and at least one access-point (AP) located within a space comprising a plurality of portions, wherein the AP is located in a particular portion of the space and a plurality of STAs are located in different portions in the space such that there are non-line-of-sight (NLOS) signals between the AP and the plurality of STAs as a result of signal obstructions within the space, processing the features using feature analysis, and detecting a location of a user motion within a particular portion of the plurality of portions of the space based on the feature analysis.
