Hyper-bandwidth, lightning quick latency, and network ubiquity are all hallmarks of 5G.  The road to 5G is indeed paved with a virtualized software edge leveraging SDN and NFV.

CSPs are re-architecting mobility networks for better performance, agility and economics.  Disaggregation and virtualization of the Radio Access Network (RAN) and Evolved Packet Core (EPC), as well as use of Self-Organizing Networks (SON) are but a few of the major technology shifts underway.

Disaggregation not only delivers increased flexibility and innovation, it also introduces a fair share of headaches.  The 5G future is one with high-capillarity cell coverage using heterogeneous technologies.  SONAR4 is driving the next level in Edge Cloud analytics for 5G.
