Beamforming is a signal processing technique used in wireless communication to direct radio signals in a specific direction, rather than broadcasting them in all directions. By adjusting the phase and amplitude of the signals sent from multiple antennas, beamforming focuses the signal toward a particular user or device, enhancing signal strength and data transmission efficiency. This technology is especially important in 5G networks, where it helps reduce interference, improve coverage, and increase network capacity, leading to faster and more reliable connections even in densely populated areas.
