Abstract
Disclosed herein is a system, apparatus, and method for using an antenna system comprising individually configurable antenna circuitries in a wireless network device to simulate the standard MU-MIMO transmissions as specified in the IEEE 802.11ac standard with antenna beamforming. The individually configurable antenna circuitries can be configured to transmit radio frequency (RF) signals with specific radiation patterns including directional beam patterns. Client devices may be grouped and antenna circuitries may be configured in such a way as to minimize inter-user interference. Frequent sounding-channel state feedback cycles and associated overhead are obviated with antenna beamforming, and no change to standard-compliant client devices is necessary. A better overall performance compared to MU-MIMO based on DSP-based beamforming as specified in the IEEE 802.11ac standard is expected.
