O-RAN Architecture and Operations
5G_208x | Expert-Led Live | 5G Access | 3
Course Duration: 1 day
This training is a technical overview of Open RAN as defined by the O-RAN Alliance. It sketches the O-RAN architecture, defines the RAN logical functions, their interfaces, and steps through the deployment operations.
Intended Audience
This course is intended for planning, engineering, operations, and systems performance teams.
After completing this course, the student will be able to:
■ Identify the key technology enablers for Open RAN initiatives
■ Sketch O-RAN architecture, describe role of each logical function and their open interfaces
■ Describe SMO architecture and functions
■ Describe the role of Non-RT RIC, Near RT-RIC towards network operations
■ Describe A1/E2 operations that helps to improve Network Performance for different usage scenarios
■ Identify the different location strategies of O-RAN components and its challenges
