As 5G networks become more open, intelligent, and disaggregated, understanding the Open Radio Access Network (O-RAN) is essential for professionals working in mobile network design, deployment, and optimisation. This short, single-module course provides a concise yet comprehensive introduction to O-RAN and its critical role in modern 5G networks.

In just three hours, you’ll explore the key architectural and functional components that make O-RAN unique. The course begins with an overview of 3GPP architectural options and how they lay the foundation for NG-RAN deployments. You’ll then examine the principles of RAN functionality and protocols before diving into the detailed architecture of NG-RAN and O-RAN.

You’ll gain a solid understanding of functional split options—crucial for enabling multi-vendor interoperability—as well as the differences between traditional and open RAN deployments. The course explains the high-level and logical architectures of O-RAN, including the roles of the Central Unit (CU), Distributed Unit (DU), and Radio Unit (RU), and how open interfaces and intelligent controllers reshape how networks are managed.
Additional topics include the application of Artificial Intelligence and Machine Learning in O-RAN, the concept of the O-RAN white box, and critical considerations around fronthaul, backhaul, and interfaces like CPRI and eCPRI.

Designed for technical professionals looking for a clear and accessible introduction to O-RAN, this course equips you with the essential knowledge needed to understand the future of radio access networks.
