What is digital beamforming?A technique using dedicated ADCs and digital processing for each antenna element to enable flexible, simultaneous control of multiple beams.
Beamforming is a radio frequency technique that uses multiple antennas to send out and focus a wireless signal toward a specific receiving device. This enables faster, more reliable data transfer compared to an omnidirectional signal. Digital beamforming is a beamforming technique that uses dedicated analog-to-digital converters (ADCs) and digital signal processing for each individual antenna element in an array. This enables very flexible and simultaneous control over the gain, phase, and timing of multiple beams transmitted or received by the array. Key benefits are improved dynamic range, interference mitigation, and scalability versus analog beamforming.
