In this lesson, learners will gain practical insight into the four core components that power Open RAN systems: the Radio Unit (RU), Distributed Unit (DU), Central Unit (CU), and RAN Intelligent Controller (RIC). The focus is on helping learners visualize how these elements interact across open interfaces and enable scalable, multi-vendor 5G networks. Using real-world examples and guided architecture breakdowns, learners will examine how functional splits work in practice, how the RIC supports AI-driven control, and how modular design supports flexibility. By the end of this lesson, learners will be able to map O-RAN components to their roles in enabling vendor interoperability and network adaptability.

In this lesson, learners will evaluate the business and technical motivations behind global Open RAN adoption. The focus is on understanding why telecom operators, governments, and equipment vendors are moving toward open network ecosystems—and what advantages they seek. Through use cases, policy examples, and industry partnerships, learners will explore key drivers such as cost savings, energy efficiency, deployment flexibility, and supply chain diversification. By the end of this lesson, learners will be able to articulate the strategic value of Open RAN and assess its real-world potential across different deployment scenarios.
