beamforming

beamforming

Directing the signals on transmitters and receivers with multiple antennas to improve transmission speed. Beamforming is accomplished by detecting the signals and sending feedback to the transmitter to adjust the phase and amplitude of the signals at its antennas. Beamforming can also work with transmitters that do not cooperate in the process by detecting incoming signals and adjusting the receiving side. See MIMO, antenna diversity, WirelessHD and WiGig.

Beamforming Bounces Signals
With highly directional transmission, beamforming can redirect signals to reach their destination. In this WiGig example, it bounces signals off the wall from the router (white unit on right) to the laptop. (Image courtesy of the Wi-Fi Alliance.)
