Airshark: Detecting Non-WiFi RF Devices Using Commodity WiFi Hardware

In this paper, the authors propose Airshark - a system that detects multiple non-WiFi RF devices in real-time and using only commodity WiFi hardware. To motivate the need for systems like Airshark, they start with measurement study that characterizes the usage and prevalence of non-WiFi devices across many locations. They, then present the design and implementation of Airshark. Airshark extracts unique features using the functionality provided by a WiFi card to detect multiple non-WiFi devices including fixed frequency devices (e.g., ZigBee, analog cordless phone), frequency hoppers (e.g., Bluetooth, game controllers like Xbox), and broadband interferers (e.g., microwave ovens).
