Abstract
Exemplary embodiments of methods and apparatuses to analyze RF signals in order to detect and classify RF devices in wireless networks are described. In one embodiment, a method includes detecting one or more radio frequency (RF) samples. Next, the method includes determining burst data by identifying start and stop points of the one or more RF samples. Next, the method includes comparing time domain values for an individual burst with time domain values of one or more predetermined RF device profiles. Next, the method includes generating a human-readable result indicating whether the individual burst should be assigned to one of the predetermined RF device profiles. Next, the method includes classifying the individual burst if assigned to one of the predetermined RF device profiles as being a WiFi device or a non-WiFi device with the non-WiFi device being a RF interference source to a wireless network.
