Systems and methods for detecting small motion vectors in a Wi-Fi motion detection system are provided. A channel is monitored over time and then evaluated to see if there is a difference, or delta, between the current time sample and other similar time samples. The delta is compared to well-known historical data that is stored in a database and used as a baseline for no motion to identify what the small motion vector is. If the small motion vector activity can't be identified, a learning module is executed to determine the closest match.
