Overview
In wireless networking, beamforming allows a base station or access point to 'shape' its radio signal so that it is concentrated in the direction of a specific device, rather than spreading out in all directions like a lightbulb.
How it Works
By precisely controlling the phase and amplitude of the signals sent from multiple antennas, the signals can be made to interfere constructively in one direction (creating a strong beam) and destructively in others (reducing interference).
Benefits
- Increased Range: The concentrated signal travels further.
- Higher Speeds: Better signal-to-noise ratio (SNR) allows for higher data rates.
- Reduced Interference: Less 'noise' for other devices in the area.
