While the concepts of beamforming have been around since the 1940s, the technology is currently playing a key role in improving modern wireless communication standards such as Wi-Fi and 5G. In combination with MU-MIMO technologies, beamforming helps users get more precise connections that boost their data speeds.
What is beamforming?
Beamforming is a technique that focuses a wireless signal towards a specific receiving device, rather than have the signal spread in all directions, like from a broadcast antenna. The resulting direct connection is faster and more reliable than it would be without beamforming.
