5G New Radio (5GNR) improves the air interface capacity and the Radio Access Network (RAN) density by utilizing small cells, RAN functional split (separation between the RAN functions such as the Radio Unit, Distributed Unit and Centralized Unit, connected via Fronthaul or Midhaul depending on the split option), Massive Multiple Input Multiple Output (mMIMO) antenna arrays and Beamforming/Beamsteering (for advanced spatial multiplexing), as well as high capacity spectrum options.
