Abstract
Disclosed are methods and systems for estimating a location of a wireless device. In some embodiments, received signal strength indication (RSSI) values of signals from a first wireless device are determined. A rate of motion of the first wireless device is then determined based on a rate at which the RSSI values vary with time. A machine learning model is conditionally updated based on the determined rate of motion, and path loss parameters are then derived from the machine learning model. The path loss parameters are used to estimate the location of the first wireless device.
