Beamforming is a signal processing technique used in wireless communication to direct the transmission or reception of signals in specific directions. By using multiple antennas, it can focus the signal towards a particular user or area, improving the quality and range of communication. This method helps reduce interference from other sources, making it more efficient. In audio technology, beamforming is applied to microphones to capture sound from a specific direction while minimizing background noise. This is particularly useful in smart devices and conference systems, where clear audio is essential. By enhancing the desired sound, beamforming improves overall performance and user experience.
