5 - 5G Massive MIMO Explained

This text explores how 5G Massive MIMO technology utilizes a stationary grid of numerous tiny antennas to electronically direct wireless signals instead of relying on physical rotation. By precisely adjusting the timing of signals sent from each antenna, the system creates a concentrated, high-gain pencil beam capable of tracking moving targets like drones over long distances. Furthermore, the base station determines the exact Angle of Arrival by measuring the microscopic time delays of returning echoes across the antenna elements. Finally, the source details how the system achieves spatial null steering by engineering intentional blind spots that prevent the transmitter from deafening its own receiver.
