Abstract
Systems and methods can support determining the physical position of a wireless device. Radio frequency sensors may be positioned within an electromagnetic environment where user equipment devices are serviced by a base station. The radio frequency sensors can receive wireless uplink signals transmitted from the user equipment devices to the base station. Data samples can be generated from the received signals. The data samples may be partitioned in time and frequency to generate spectrum tiles. The spectrum tiles may be statistically aggregated to reduce the quantity of data samples. A clustering algorithm may be applied to the statistically aggregated spectrum tiles to determine clusters of spectrum tiles. Signal parameters associated with respective clusters of spectrum tiles may be computed. Physical locations associated with user equipment devices can be estimated from the signal parameters associated with the respective clusters of spectrum tiles.
