Samer Hanna, Samurdhi Karunaratne, Danijela Cabric

TL;DR
WiSig is a comprehensive WiFi dataset designed to facilitate the development of RF fingerprinting methods that are robust to channel and receiver variations, by providing extensive, real-world captured data.
Contribution
The paper introduces WiSig, a large-scale, publicly available WiFi dataset with extensive captured data to support channel and receiver agnostic RF fingerprinting research.
Findings
Changing receivers degrades classifier performance.
Data captured on different days affects identification accuracy.
More diverse data reduces performance degradation.
Abstract
RF fingerprinting leverages circuit-level variability of transmitters to identify them using signals they send. Signals used for identification are impacted by a wireless channel and receiver circuitry, creating additional impairments that can confuse transmitter identification. Eliminating these impairments or just evaluating them, requires data captured over a prolonged period of time, using many spatially separated transmitters and receivers. In this paper, we present WiSig; a large scale WiFi dataset containing 10 million packets captured from 174 off-the-shelf WiFi transmitters and 41 USRP receivers over 4 captures spanning a month. WiSig is publicly available, not just as raw captures, but as conveniently pre-processed subsets of limited size, along with the scripts and examples. A preliminary evaluation performed using WiSig shows that changing receivers, or using signals…
