Abstract: Systems and methods for wireless communications are disclosed. More particularly, aspects generally relate to an apparatus for wireless communications. The apparatus generally includes an interface for communicating with a plurality of wireless nodes via a plurality of antennas, and a processing system configured to determine a power state of each of the plurality of wireless nodes, and change from a first antenna mode used for communicating with the wireless nodes using a first number of spatial streams to a second antenna mode used for communicating with the wireless nodes using a second number of spatial streams, based on the determined power states of the wireless nodes.
