Course Description

Open RAN, and particularly the O-RAN standardized by the O-RAN Alliance, is currently one of the hottest topics in the area of wireless mobile communications. O-RAN promises considerable OPEX and CAPEX savings for mobile network operators (MNOs), fostering innovation and competition in the Radio Access Network (RAN) through open interfaces, virtualization, and architecture developments that maximize the potential for innovating RAN solutions and services provided by a multitude of companies.

This course provides first an overview of the current 3GPP-based RAN architecture, covering different deployment options such as D-RAN, C-RAN, and V-RAN. In this context, RAN splitting options are discussed, focusing on the higher and lower layer split (HLS and LLS, respectively). Following that, the limitations and overheads resulting from the proprietary aspects of the 3GPP-based non-open RAN solutions are analyzed, setting the ground for the presentation of the O-RAN framework.

O-RAN is first introduced through the presentation of the relevant standardization effort, the eco-system, the involved parties, and the current deployment status. Next, the technical aspects of the O-RAN are analyzed, including the architecture, interfaces, software and hardware aspects and the role of virtualization. Detailed analysis of the role of the RAN Intelligent Controllers (RIC) is provided, explaining how the architecture of the RICs opens the RAN to innovative solutions and features, including the deployment relevant AI/ML workflows. Finally, the instructor presents case studies from early O-RAN adopters, summarizing the main findings from these early deployments and discussing potential O-RAN challenges and threats.

Advanced Topics in Wireless: 5G NR, MTC, and Open RAN Course Series
Participants taking the three courses in the Advanced Topics in Wireless series will develop a comprehensive view on the 5G/NR technology, a profound understanding of the implementation aspects of all the ITU-specified use case categories, i.e. enhanced Mobile Broadband (eMBB), mIoT and URLLC, and a robust foundation on the network architecture evolution technology enablers towards fully open radio access networks. Complete all three courses in this series to earn a digital badge.

Special note:  This course is one of three courses in the Advanced Topics in Wireless series.  The three courses in this series include:

  1. 5G RAN and Core Network: Architecture, Technology Enablers and Implementation Aspects, 24-25 April 2024
  2. O-RAN: Disrupting the Radio Access Network through Openness and Innovation, 8-9 May 2024
  3. Machine Type Communications in 5G and Beyond, 22-23 May 2024
