Welcome to O-RAN Part 2: Disaggregation of the 5G RAN
5G_111d | On-Demand | 5G Access | 1
Course Duration: 1 hour
This training, part of a multi-part Welcome to O-RAN series, provides insights into how aspects of 5G RAN disaggregation contribute to an open, O-RAN architecture. In this course, you will learn how RAN disaggregation lends itself to an open, virtual, multi-vendor RAN. You will explore open fronthaul (Option 7-2x) for O-RAN and how O-RAN nodes are implemented in the O-RAN reference architecture.
Intended Audience
This course is designed for a broad audience of personnel working in the wireless industry.
Objectives
After completing this course, the learner will be able to:
■ Describe key drivers for 5G RAN disaggregation (RAN latency, fronthaul bandwidth, resource pooling)
■ Explain the 5G split RAN architecture
■ Identify different RAN components and interfaces (CU, DU, RU and Fronthaul, Midhaul, Backhaul)
■ Describe the implementation of the 5G RAN in an O-RAN architecture (O-CU, O-DU, O-RU, O-Cloud)
■ Explain O-RAN operational interfaces and the need for open fronthaul
■ Describe O-RAN management interfaces (O1, O2, E2 and A1) and their operations
