Abstract
Systems, methods, and devices enable the implementation of antenna diversity techniques. Devices include a first wireless communications device that includes a plurality of antennas, and a transceiver coupled to the plurality of antennas and configured to send and receive data in accordance with a wireless transmission protocol, while the peer wireless communication device may have a single antenna or multiple antennas. Devices also include a processor configured to, in a first mode, calculate an angle of arrival (AoA) with the plurality of antennas or an angle of departure (AoD) associated with single antenna, and, in a second mode, send data to and receive data from a second wireless communications device via at least a first antenna of the plurality of antennas, where the first antenna is selected by the processor based on one of a first plurality of signal measurements between the first and second wireless communications devices.
