O-RAN System Training

Online, self-paced, pre-recorded course

Course Overview
The course covers the joint design of technology and ecosystem aspects in Open RAN networks. The technology enablers include open networking, virtualization, HW/SW disaggregation, and network intelligence.  The course discusses Open RAN concepts, architecture, use cases, functions, and interfaces. It also covers 5G topics including network slicing and how it fits into the O-RAN area.

The central point for the standardization of Open RAN is the O-RAN Alliance, but relations with other entities, such as TIP (Telecom Infra Project), and 3GPP are also emphasized.

The course is an online, self-paced course with 10+ hours of pre-recorded videos.

Who Should Attend?

Participants with a background in either system or networks design should benefit from participating. The focus is on Open RAN networks and it's relation to 5G and participants with a general background in mobile networks will be able to follow the course. This includes industry, network operators, regulators, and managers in this field as well as researchers, students in academia.
