Glossary  >  Beamforming



Beamforming is a technology that focuses radio signals in a specific direction, rather than dispersing the signal in all directions. This technique significantly enhances signal strength, reliability, and throughput.

Beamforming operates through multiple antennas situated close together, each transmitting the same signal at slightly different times. This timing difference causes the signals to overlap, creating constructive interference where the signal strengthens, and destructive interference where it weakens. When properly implemented, beamforming directs the enhanced signal towards a specific receiving device or direction.

The concept of beamforming has been around since 1905, but it is still utilized in modern technologies such as Wi-Fi and 5G. In Wi-Fi networks, beamforming concentrates the signal towards the receiving device, leading to faster and more reliable connections. It also extends coverage to areas that were previously difficult to reach.

5G employs beamforming to address issues like interference and range limitations. Techniques such as massive MIMO (multiple-input multiple-output) and hybrid beamforming are integral to 5G technologies.

Example of Beamforming in a sentence:

"Beamforming allows you to deliver high signal quality to a specific receiver or direction without increasing broadcast power."
