Abstract
Example method includes: receiving, by an access point in a wireless local area network (WLAN), a plurality of wireless interference signals from an interfering device; deriving, by the access point, a fast Fourier transformation (FFT) pattern from the plurality of wireless interference signals received from the interfering device; transmitting, by the access point, the FFT pattern to a centralized repository that is remote to the access point; receiving, by the access point, a classifier from the centralized repository; and classifying, by the access point, the interfering device into a specific device type using the classifier received from the centralized repository based on the FFT pattern.
