New technologies and millimeter wave spectrum allocations have made beamforming
antennas both commercially feasible and necessary to deliver on 5G.
Massive MIMO is an evolutionary leap forward that uses more elements to support multi-user MIMO, beamforming
and typically 8 or 16 streams to enable a major boost in network capabilities.
The fully digital control system enables simultaneous beamforming
in multiple directions from a single massive-element AAS unit and efficiently implements high-speed and high-capacity communication without interfering with adjacent users through spatial multiplexing.
makes use of both analog beamforming
and digital precoding techniques to intelligently form the patterns transmitted from a large antenna array.
Most solutions select the optimal beamforming
group based on the full CSI feedback by all potential users, like semi-orthogonal user selection algorithm (SUS)  and minimum of the frobenius norm of the pseudo-inverse algorithm (MFNPI) .
The network takes advantage of patented spectrum reuse, advanced beamforming
technologies and 60 MHz of spectrum for significantly enhanced connectivity.
Amazon's proprietary software for wake word recognition, beamforming
, noise reduction, and echo cancellation
Nokia's 3D Beamforming
, for downlink and uplink, is an early innovation and has been field tested in Hangzhou, China.
technique is widely used in relay systems [13-15] as an effective way to improve the received signal-to-noise ratio (SNR) at the destination.
Then a corresponding algorithm [4, 8, 9] is selected to control beamforming
parameters of phased array antennas, directing the beam at the target node.
Cephasonics' ultrasound technology, including its AutoFocus beamforming
technology, has won multiple industry awards for innovation.
Its Wi-Fi systems use directed beamforming
technology, which delivers more efficient coverage and capacity and reduces the amount of radio waves in the coverage area.
