What is beamforming?

Beamforming is a type of RF (radio frequency) management in which an access point uses multiple antennas to send out the same signal.

By sending out multiple signals and analyzing the feedback from clients, the wireless LAN infrastructure can adjust the signals it sends out and determine the best path the signal should take in order to reach a client device. In a sense, beamforming shapes the RF beam as it traverses the physical space of the enterprise.
