Transition Toward Open & Interoperable Networks - 5G Americas - November 2020

Open Radio Access Networks (Open RAN) is a concept that involves the interoperability of open hardware, software, and interfaces for cellular wireless networks. Open RAN architecture combines a modular base station software stack with off-the-shelf hardware, which allocates baseband and radio unit components from isolated suppliers to operate seamlessly together, whether or not elements of the RAN are virtualized or disaggregated.

Even though Open RAN is gaining momentum, it is at an early phase of commercial adoption by the global wireless community. This white paper examines aspects of software/hardware disaggregation, open interfaces, multi-vendor interoperability, the Open RAN ecosystem, and the role of AI and machine learning in network management and automation.

In addition, the white paper covers the following topics:

  • Overview and goals of Open RAN
  • Operator trials and deployments
  • Introduction to the ecosystem of Open RAN development bodies
  • Open RAN architectural considerations
  • Role of Artificial Intelligence (AI) & Machine Learning (ML) initiatives in Open RAN
  • Management, orchestration and automation of Self-Organizing Networks (SON) for varying use cases
  • Key motivations & challenges faced by operators in adoption of a multi-vendor Open RAN platform

Interesting document from 5G Americas about Open RAN Status!
