What is the main advantage of beamforming?

Beamforming controls the directionality of the transmission or reception of a signal on an antenna array. Beamforming improves the spectral efficiency by providing a better signal-to-noise ratio (SNR). Working with other antenna technologies such as smart antennas and MIMO, beamforming boosts cell range and capacity.

What are beamforming techniques?

Beamforming is a technique used to improve the signal-to-noise ratio of received signals, eliminate undesirable interference sources, and focus transmitted signals to specific locations. Beamforming is central to systems with sensor arrays, including MIMO wireless communications systems such as 5G, LTE, and WLAN.

Is beamforming harmful?

According to [5], beamforming may pose an health risk, because 5G gNBs employing this feature will increase the effective radiated power.
