The course provides a technical overview of Open RAN and specifically O-RAN from the O-RAN Alliance.
The course outlines the O-RAN architecture and terminology, central functions and concepts like SMO, Non-RT RAN Intelligent Controller, Near-RT RAN Intelligent Controller, O-CU, O-DU, O-RU and O-Cloud.
Relevant interfaces are described, along with a few simple use case examples. The motives and objectives for Open RAN are outlined, as well as its relationship to technical specifications from e.g. 3GPP, ETSI and IETF.
