Beamforming+

Beamforming is a radio wave technology written into the next generation IEEE Wi-Fi 802.11ac
standard. Traditionally, the router broadcasts the data in all directions when broadcasting a Wi-Fi
signal. With beamforming, the router transmits radio signal in the direction of the client, thus
creating a stronger, faster and more reliable wireless communication.
The key benefits of beamforming are:

Extended Wi-Fi coverage and fewer dead spots.

Stable Wi-Fi connection for voice and HD video.

Better Wi-Fi throughput.

Less unnecessary RF interference.
The following figure shows the wireless transmission when Beamforming+ is disabled.
