Abstract
This document describes techniques using, and devices embodying, radar gesture sensing using existing data protocols. These techniques and devices enable transmitting data according to an existing data protocol, modulating the data on a radar field to transmit to another device, and sensing user gestures by analyzing reflections of portions of transmitted data by the transmitting or receiving device. Techniques are also described to filter received signals based on addressing information in the transmitted data to limit gesture recognition at a receiving device to transmitting devices known to the receiver.
