1. A computer-implemented method comprising:

  • modulating a radio frequency (RF) signal with data according to a data protocol, the data comprising a training sequence in accordance with the data protocol;

    emitting a radar field using the modulated RF signal, the radar field including the training sequence;

    receiving 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

    analyzing the portions of the reflection signals corresponding to the training sequence to determine the gesture.
