Course 815 O-RAN System Overview

Dr. Marcin Dryjanski, consultant from Rimedo Labs, Poland, is teaching this 2-day course about O-RAN Systems. The course covers joint design of technology and ecosystem aspects in Open RAN networks. The technology enablers include open networking, virtualization, HW/SW disaggregation, network intelligence. The course discusses Open RAN concept, architecture, use cases, functions and interfaces. With further network densification and high sophistication of the relation between multiple layers and operators and network elements require network management solution based on Artificial Intelligence (AI). The central point is the O-RAN Alliance, but relation to other entities, like TIP (Telecom Infra Project), and 3GPP is also emphasized.
