Abstract: In one aspect, a system includes a station device configured to transmit a signal; multiple access point devices in connection with the station device, the multiple access point devices configured to receive the signal transmitted from the station device, wherein the multiple access point devices are configured to convert the signal into a measurable form; and a processing unit operably connected to the multiple access point devices. The processing unit is configured to, for each subcarrier within the signal received by the multiple access point devices, determine a measurement of channel state information including an overall shape of the signal; determine a magnitude distance for each subcarrier; and determine a location of the station device based on a fit of the magnitude distance to a model, wherein the model is based on an environment with one or more obstacles causing an obscuration of the signal.
