What gains can be realized by massive mimo of 5g?

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.

What can massive MIMO do?

Massive MIMO improves network coverage and capacity through the use of the three multi-antenna technologies – beamforming, null forming and spatial multiplexing – shown in Figure 1. All three are applicable to both the downlink (DL) and the uplink (UL).

What is MIMO and what are its benefits?

MIMO is often used for high-bandwidth communications where it's important to not have interference from microwave or RF systems. For example, it's frequently used by first responders who can't always rely on cell networks during a disaster or power outage or when a cell network is overloaded.

How MIMO creates performance gains in a fading channel?

Three main performance gains can be achieved under massive MIMO system: array gain, spatial diversity gain and spatial multiplexing gain. An increase in the energy efficiency means that the received SNR is increased from the coherent combining of the signals toward where users are located.

What is gain in MIMO antenna?

The MIMO antenna without the metasurface offers a peak measured gain of 5.8 dBi, whereas the metasurface with a copper backplane is 8.5 dBi.
