Beamforming directivity [Part 1, Fundamentals of mmWave communication]

Antenna arrays are essential in mmWave communication to achieve a directional transmission that focuses the wireless signal on the receiver. In this video, the first in a series, Prof. Emil Björnson demonstrates how beamforming directivity is achieved in practice by transmitting the same signal from multiple antenna elements - the more antennas, the higher directivity. He both explains the underlying theory and demonstrates the key principles experimentally. Beamforming is essential at both base stations and user devices when using the 5G mmWave bands, but it has long been utilized at base stations in the lower frequency bands.

The experiments are carried out using the TMYTEK Developer Kit https://www.tmytek.com/solutions/mmwa... which the company kindly lent us. This is not a sponsored video.
