Session 3: Network Architecture Breakdown | Open RAN vs. Traditional Networks

Hello and welcome to Session 3 of our Open RAN learning series! In this session, we will delve into the intricate world of network architecture, shedding light on the RAN network, transport network, and core network. Additionally, we will provide a real-world perspective by showcasing components of a traditional network tower, including antennas, radio units (RRUs), and baseband units (BBUs). Join us as we explore the distribution of protocol layers in these components, offering a comprehensive understanding of both Open RAN and traditional network infrastructures.

Overview of Network Architecture
Session 3 of our Open RAN series offers a high-level overview of network architecture, focusing on three key segments: the RAN network, transport network, and core network. These segments form the backbone of modern telecommunications infrastructure, each playing a crucial role in ensuring seamless connectivity. The session aims to provide a comprehensive understanding of how these networks interconnect and function together to deliver reliable communication services.

Deep Dive into RAN, Transport, and Core Networks
During the session, we will delve into each network segment, starting with the RAN network. This segment encompasses the radio access network, which includes base stations and antennas that connect users to the core network. We will then explore the transport network, responsible for carrying data between the RAN and core networks. Lastly, we will discuss the core network, which handles tasks such as call routing, network management, and data processing. By understanding these segments, viewers will gain insight into the complexity of modern network infrastructures.

Real-Life Examples and Component Breakdown
To provide a practical perspective, the session will showcase real-life examples of traditional network towers. These towers house crucial components such as antennas, radio units (RRUs), and baseband units (BBUs), which are essential for network operations. Additionally, we will explain how protocol layers are distributed across these components, offering a glimpse into the intricate workings of network protocols. Overall, Session 3 aims to demystify network architecture, making it more accessible to beginners in the field of telecommunications.
