Capacity exhaustion is a growing challenge for network operators due to the rapidly increasing data consumption by mobile broadband (MBB) subscribers. Rather than addressing this by densifying 4G networks with new sites, 5G New Radio (NR) offers operators the opportunity to meet growing demand and improve performance through the efficient use of new frequency bands at existing sites. The latest Ericsson Technology Review article explains how deploying 5G NR with mid bands (3-6GHz) at existing 4G sites enables maximal reuse of site infrastructure investments as well as delivering a significant performance boost. By adding NR with 100MHz unpaired spectrum, it is possible to achieve eight times higher downlink capacity relative to LTE (2x50MHz paired spectrum). Massive MIMO techniques, such as beamforming and multi-user MIMO, deliver improved downlink data rates both outdoors and indoors.
