O-RAN Architecture Overview
TPR1052d | On-Demand | 5G Access | 2
Course Duration: 4 hours
The Open RAN initiative of the O-RAN Alliance defines O-RAN architecture that facilitate deployment of 5G RAN to support uses cases of mobile broadband, edge computing, and IoT. This training presents an overview of O-RAN architecture, components of 5G RAN and its interfaces and likely deployment scenarios.
Intended Audience
This course is intended for planning, engineering, and systems integration teams.
Objectives
After completing this course, the student will be able to:
■ Identify key drivers for 5G RAN based on O-RAN architecture
■ Sketch O-RAN architecture for 5G RAN and describe role of each logical functions
■ Describe SMO architecture and its role in interfacing with external applications
■ Identify the importance of Open Interface Split Option 7-2x
■ Define RAN slicing and step through RAN slicing deployment using O-RAN
