Open RAN (O-RAN) Webinar Collection

Open RAN Webinars

In the past couple of months, we delivered several Open RAN Webinars together with Intelefy University. In this post, you can find the collection of them, in the particular order, where the first one serves as an overview and high-level discussion, whereas the others dig more and more into details of O-RAN, as specified by O-RAN ALLIANCE.

Note: If you watch, one by one, there is a certain overlap, nevertheless, they complement each other.

5G, Private Mobile Networks and Open RAN

We start with the 1-hour session on „5G, Private Mobile Networks and Open RAN”. We start by speaking about 5G and its complexity. Later, you learn about the concept of Private Mobile Networks and what role they play in mobile communications moving forward. Next, we get to the benefits and potential of Open RAN, and why you should pay attention to its development now. Finally, you learn how those three puzzles (i.e., 5G, Private Mobile Networks, and O-RAN) fit together for the future of wireless.

The following sections are included in the session:
✔︎ Mobile wireless systems evolution
✔︎ 5G overview
✔︎ 5G complexity
✔︎ Private mobile networks
✔︎ From RAN to O-RAN transition

O-RAN Architecture and Use Cases

The second talk provides an overview of O-RAN (as defined by O-RAN Alliance), along with the architecture details covering interfaces, nodes, and implementation options. Later, provide an overview of the RAN Intelligent Controller (RIC) along with O-RAN Alliance’s use cases. One of the most important of those is then discussed in detail, namely Traffic Steering (TS) along with sample simulation scenarios and results provided. In this, AI/ML schemes are used to adjust the system’s operation based on the operator’s choices defined as policies.

The following sections are included in the session:
✔︎ O-RAN Overview and Architecture
✔︎ Resources and entities involved in O-RAN developments
✔︎ RAN Intelligent Controller (RIC)
✔︎ O-RAN Use Cases
✔︎ Traffic Steering Use Case and simulations (developed by Rimedo Labs R&D team)

O-RAN Architecture and RAN Intelligent Controller (RIC)

In the final 1-hour session, we discuss O-RAN entities and architecture along with the deployment options as defined by O-RAN ALLIANCE. Later, we focus specifically on the RAN Intelligent Controller (RIC) and expand on what was provided in the second webinar. The RAN Intelligent Controller (RIC) developed by the O-RAN Alliance is intended to enable AI/ML-based access to the elements in the radio network (called E2 Nodes, like O-CU-UP, O-CU-CP, or O-DU). We speak about the details of RIC, including the split onto Near-Real-Time RIC (Near-RT RIC) and Non-Real-Time RIC (Non-RT RIC), along with the O-RAN Alliance-defined interfaces related to both, namely E2 and A1. We also discuss xApps and rApps, what are the differences between them, and some examples of those.

The following sections are included in the session:
✔︎ O-RAN definitions and entities
✔︎ O-RAN architecture and deployment options
✔︎ RAN Intelligent Controller (RIC)
✔︎ Near-RT RIC and E2 Interface
✔︎ Non-RT RIC and A1 Interface
