Abstract
A first network device can implement null beamforming functionality to generate a NULL at a receive port of a second network device. In one embodiment, the first network device can estimate beamforming parameters to be used for transmitting the data signal to a first receive port of the second network device and for generating a null signal at a second receive port of the second network device, so that the second network device does not receive the data signal at the second receive port. In another embodiment, the first network device can estimate beamforming parameters to be used for transmitting the data signal to a receive port of the second network device and for generating a null signal at a receive port of a third network device, so that the receive port of the third network device does not receive the data signal.
