O-RAN: Architecture, Implementation & Operation

Table of Contents:

Part 1: ORAN / An Overview

  • Architecture overview
  • Artifical Intelligence (AI) and Machine Learning (ML) in Context with O-RAN
  • Standardization and Interaction among Players (incl. incumbent RAN-vendors)
  • Functional split options and O-RAN
    • Focus on 7.2X between O-RU and O-DU

Part 2: Architecture Details: Open Cloud, Virtualization & Acceleration

  • HW-virtualization and VM's vs OS-virtualization and containers
    • e.g. performance differences, comparison with dedicated HW-solutions
  • Open Cloud and its components
    • Edge Cloud, Regional Cloud, Core Cloud
    • Xhaul: Fronthaul and Backhaul
  • Acceleration options: FPGA, GPU, eASIC, Inline, look-aside

  • Kubernetes and Docker
