Beamforming
Wireless
Overview
Beamforming adjusts antenna phase/amplitude to improve received signal in useful directions. It needs channel information and compatible capability; it does not eliminate obstacles, interference or airtime contention. Distinguish multiple spatial streams from a claim that every client gets dedicated bandwidth.
