Abstract

Apparatuses and methods for sharing data between wireless devices based on one or more user gestures are disclosed. In some implementations, a wireless device may include a number of antenna elements configured to beamform signals in a plurality of transmit directions, with each of the transmit directions corresponding to one of a number of antenna sectors. Each of the antenna sectors may represent a unique set of phase shift values and gain values applied to the plurality of antenna elements, for example, so that the wireless device may beamform data transmissions in a transmit direction corresponding to a position of a target device in response to a user gesture.
