O-RAN (or Open RAN) opens new avenues of service innovation and agility for telcos by breaking the Radio Access Network (RAN) into its component parts, each of which can be separately reconfigured. O-RAN standards are freely accessible to all third-party software developers, who can develop new types of services and innovate on the RAN Intelligent Controller (RIC) by building xApps and rApps. This enables telcos to make their networks a much more relevant resource for both enterprise and consumer applications.

Arguably the open RAN’s biggest claim is the potential to enable telcos to avoid vendor lock-in by replacing vendor-proprietary interfaces with a fully disaggregated RAN based on open standards.

Automation will be key to managing the lifecycle of disaggregated, cloud-native RAN functions. O-RAN can bring down the network deployment and operation cost by evolving the network in a continuous integration/ continuous delivery (CI/CD) manner rather than through generational investment cycles.

This course covers all the important topics that are required to have a good and comprehensive learning of the O-RAN technology. The relevant standards of the O-RAN alliance have been discussed to describe the O-RAN architecture and working, as well as the O-RAN open interfaces.
