Systems, methods, and devices seamlessly playback data files using one or more wireless connections. Methods include identifying a plurality of combinations of antennas based on a plurality of available antennas for a wireless communications device, and generating, using a processing device included in a multiple-input-multiple-output (MIMO) device, 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 included in a multiplexed spatial stream. Methods also include selecting, using the processing device, at least two antennas from the plurality of combinations of antennas that have the closest values of quality metrics to each other, wherein the plurality of combinations of antennas comprises antennas associated with different streams included in the multiplexed spatial stream.

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

Implementations disclosed describe systems and methods to optimize allocation of wireless subcarriers to station devices in wireless networks. In an example implementation, the disclosed techniques may include determining, by a station device in a wireless network, that a current set of wireless subcarriers, allocated by an access point device of the wireless network for the station device, is to be changed, generating, by the station device, a feedback information characterizing a current state of one or more of the wireless subcarriers, and sending, by the station device, the feedback information to the access point device.

Autonomous feedback for efficient allocation of wireless subcarriers

Systems, methods, and devices select antennas to enhance the range and throughput of wireless communications devices. Methods include identifying a plurality of combinations of antennas based on a plurality of available antennas for a wireless communications device, and generating, using a processing device included in a multiple-input-multiple-output (MIMO) device, a plurality of quality metrics including at least one quality metric for each of the identified combinations of antennas, where each of the at least one quality metrics represents a signal quality of a signal associated with each of the plurality of antennas, and wherein the signal is a spatial stream. Methods further include selecting at least two antennas from the plurality of combinations of antennas based, at least in part, on the plurality of quality metrics, where the at least two antennas are selected for use by the wireless communications device during a transmitting or receiving operation.
