Beginners: Open RAN Terminology – Virtualization, Disaggregation & Decomposition

Descargar para leer sin conexión

This video/presentation explains Open RAN terminology that different people, companies and organizations use. It starts with open interfaces and then looks at radio hardware disaggregation and compute disaggregation. Moving from 2G/3G/4G to 5G, it also explains the Open RAN approach to a decomposed architecture with RAN functional splits.

This forms part of our #OpenRAN videos where we discuss open movement, networks and #ORANalliance.

The corresponding video is available at: https://www.youtube.com/watch?v=xJykqLCrHQI
