5G_113d | On-Demand | 5G Access | 1
Course Duration: 1 hour
This course provides a technology introduction to RAN Intelligence Controller (RIC) Apps and external enrichment in O-RAN operations. You will learn the role of xApps and rApps in O-RAN and the benefits and use of external enrichment data in O-RAN operations. You will also explore how O-RAN can use AI/ML to improve the performance of the RAN.
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:
