Why do we use massive MIMO?

Benefits of massive MIMO

Massive MIMO contributes to increased capacity first by enabling 5G NR deployment in the higher frequency range in Sub-6 GHz (e.g., 3.5 GHz); and second by employing MU-MIMO where multiple users are served with the same time and frequency resources.

At what frequency onwards can you start using massive MIMO?

Massive MIMO is the new wireless access technology in 5G, in both sub-6 GHz and mmWave bands.

What are the main parameters affecting the performance of a massive MIMO antenna?

Factors influencing performance in real MIMO fading scenarios include a realistic propagation channel, mutual coupling between the antennas, the antenna radiation efficiencies, and the presence of the user, among other factors.

How does massive MIMO work?

Massive MIMO employs a large number of antenna elements within a single antenna panel of a 5G base station and uses spatial multiplexing, diversity and beamforming to increase network capacity, throughput and radio link quality. The additional capacity is used to serve multiple simultaneous users.
