The Radio Access Network of 4G LTE is evolving and operators are getting ready to deploy the 5G Next Generation RAN (NG-RAN). Cloud and virtualization and Open RAN are essential for an agile and flexible access network with RAN vendor inter-operability. 5G NG-RAN introduces a split architecture that impacts how operators design and deploy the 5G RAN network functions and the related transport network and fiber connectivity.

A high-level technical overview to personnel involved in product management, marketing, planning, design, engineering, and operations

After completing this course, the student will be able to:
■ Step through the evolution of 4G LTE RAN to C-RAN, Virtualized RAN (V-RAN) and Open RAN (O-RAN)
■ Sketch architecture of 5G NG-RAN and split architecture
■ Discuss the use of CPRI/eCPRI and Ethernet for the fronthaul and backhaul networks
■ Sketch the connectivity of 4G eNB and 5G gNB
