Beamforming is a technique that changes how signals are sent and received. Instead of broadcasting a signal in every direction, like a typical omnidirectional antenna does, beamforming allows the signal to focus in a specific direction. This focused beam offers faster speeds, better reliability, and reduces interference for other devices nearby.

Beamforming works by using antenna arrays. Each element in an array transmits the same signal at slightly different times. The overlapping signals interact, creating areas where the signal is stronger and areas where it’s weaker or even cancelled out. This smart interference pattern creates a focused beam aimed at the device that needs the signal.

The main benefit of beamforming is improved signal quality. When the signal is directed, the receiving device gets a much stronger and clearer connection. This means faster data transfer, fewer errors, and better overall performance without the need for more power. Plus, by reducing signal spread in other directions, beamforming can help cut down interference for other nearby users and devices.
