Enhancement of range and throughput for multi-antenna wireless communications devices

A device comprising:

• at least one transceiver;
• a processing device comprising one or more processors configured to:
• identify a plurality of combinations of antennas based on a plurality of available antennas for a wireless communications device, wherein the plurality of available of antennas numbers more than two;
• generate a plurality of quality metrics comprising at least one quality metric for each of the identified combinations of antennas, wherein each of the at least one quality metrics represents a signal quality of a signal associated with each of the plurality of antennas, wherein the signal is a spatial stream, and wherein the plurality of quality metrics are generated responsive to determining a number of multiplexed data streams included in the spatial stream is greater than one;
• and
• select at least two antennas of the wireless communications device based, at least in part, on a similarity between values of a quality metric for each of the at least two antennas, wherein the selected at least two antennas have the closest values of quality metrics, and wherein the at least two antennas are selected for use by the wireless communications device during a transmitting or receiving operation,
• wherein the at least one transceiver and the processing device are included in a MIMO device.
