Three-Dimensional Beamforming (3DBF), also known as Full-Dimension Beamforming, is an advanced signal processing technique used in wireless communication systems. This technology enables the shaping and steering of the antenna beam in both horizontal and vertical dimensions. In traditional beamforming, the antenna beam is directed in one plane, typically the horizontal one. However, 3DBF takes this a step further by allowing the beam to be directed in both horizontal and vertical planes. This results in a more efficient use of the radio spectrum and improved network performance. 3DBF technology offers several advantages. Firstly, it enhances signal quality by focusing the transmission energy towards the intended user and minimising interference to other users. Secondly, it improves the overall network capacity by allowing multiple users to share the same frequency resources. Lastly, it extends the coverage area of a base station, reducing the need for additional infrastructure.
