Spirent Massive MIMO Test Solution | Sub 6GHz


Simplifying 5G Conductive RF Testing

Massive multiple input multiple output (MIMO) is a key physical layer technology for 5G applications, which involves the use of large-scale antenna arrays that contain as many as 256 elements. Implementing 3D beamforming along with massive MIMO technology improves the capacity limitation of an entire 5G system by adding data streams, increasing the signal to noise ratio, and reducing interference.

In an ideal open space environment, the massive MIMO antenna array can create well-shaped high-gain beams for target devices, but in a real cellular network, propagation conditions are very complicated - the signal or beam may be reflected or scattered through different objects; the plane wave can form into multiple signal clusters (paths) with different delays, orientation of arrival and angle spread; and the beam shape can also change due to the propagation environment.
