Abstract
A first network device includes a calibration module configured to receive a training signal from a second network device. The training signal indicates the second network device is capable of adjusting beamforming weights associated with the second network device based on a steering matrix received from the first network device. A steering module is configured to determine a first steering matrix for the second network device based on the training signal. The steering module is configured to transmit the first steering matrix to the second network device for adjustment of the beamforming weights associated with the second network device.
