Abstract

A signal analysis mechanism for processing and classifying an RF signal received at a WLAN device. A plurality of spectral data captures comprising time-frequency data and receive signal strength indicator (RSSI) data associated with the RF signal received at the WLAN device are generated. The time-frequency and RSSI data of each of the plurality of spectral data captures is processed to determine whether each spectral data capture is a narrowband signal capture. If the plurality of spectral data captures are narrowband signal captures, a narrowband interference signal type associated with the received RF signal is determined based, at least in part, on a plurality of parameters associated with the narrowband signal captures.
