Radar gesture sensing using existing data protocols

A radar system comprising:

• a first device configured to:
• modulate a radio frequency (RF) signal with data formatted according to a data protocol, the data comprising at least a training sequence in accordance with the data protocol;
• emit a radar field using the modulated RF signal, the radar field including the training sequence;
• a second device configured to:
• receive one or more reflection signals caused by a reflection of the radar field off an object performing a gesture within the radar field, the reflection signals containing portions corresponding to the training sequence;
• and
• analyze the portions of the reflection signals corresponding to the training sequences to determine the gesture.

A device comprising a gesture sensing component, the gesture sensing component configured to:

• modulate a radio frequency (RF) signal with data formatted according to a data protocol, the data comprising at least a training sequence in accordance with the data protocol;
• emit a radar field using the modulated RF signal, the radar field including the training sequence;
• receive one or more reflection signals caused by a reflection of the radar field off an object performing a gesture within the radar field, the reflection signals containing portions corresponding to the training sequence;
• and
• analyze the portions of the reflection signals corresponding to the training sequence to determine the gesture.
