Abstract: Network densification is an essential mechanism expected to enable next generation 5G networks to meet the 1000-fold increase in capacity. This article explores network densification as the key mechanism for wireless evolution over the next decade. Network densification includes Spectral densification (densification over space) and spatial aggregation (densification over frequency). Key enablers of network densification such as heterogeneous network, D2D, NSC are discussed. Challenges associated with network densification such as energy efficiency, interference, handoff are also discussed.
