VRAN and Open RAN Overview
TPR1047d | On-Demand | 5G Access | 2
Course Duration: 4 hours
The virtualized RAN and Open RAN initiative of O-RAN Alliance are introduced into the 5G RAN to support 5G uses cases of mobile broadband, edge computing, and IoT. This training presents an overview of 5G RAN and gNB Split architecture, concepts of virtualization in RAN, role of RU, gNB-DU and gNB-CU and their connectivity of CPRI, eCPRI and Ethernet.
Intended Audience
This course is intended for planning, engineering, operations, and systems performance teams.
Objectives
After completing this course, the student will be able to:
■ Sketch the network architecture of 5G RAN and understand the placement of RAN components
■ Draw the connectivity of RAN components and identify the role of CPRI and Ethernet
■ Highlight the benefits of virtualization in RAN and potential use cases of virtualization
■ Sketch O-RAN architecture for 5G RAN and define role of Split Option 7-2x
■ Define RAN slicing and step through RAN slicing deployment using O-RAN
