Systems, methods, and other embodiments associated with beamforming with steering submatrix selection are described. According to one embodiment, an apparatus includes a steering matrix cache unit configured to store a steering matrix. The apparatus also includes a read control unit configured to select a steering submatrix from the steering matrix based, at least in part, on packet transmission instructions associated with a packet being processed for transmission. The read control unit is also configured to provide weights from the selected steering submatrix to a transmitter transmitting the packet.
