Wireless networks are undergoing a major transformation as the industry embraces open architectures, software-defined platforms, and AI-driven innovation. This application note introduces the Open Centralized Unit/Distributed Unit (OCUDU) initiative and explains how a shared, open-source CU/DU software stack could reduce development complexity, improve interoperability, and accelerate the pace of 5G and 6G innovation across the wireless ecosystem.

In this application note, you’ll learn what OCUDU is and how it can:

• Accelerate innovation through a shared, open-source CU/DU platform
• Lower barriers to entry for researchers, startups, and innovators
• Unlock AI-driven advancements through open and accessible code
• Foster ecosystem-wide collaboration across industry, academia, and government

This note is ideal for wireless researchers, network engineers, and technology leaders seeking to understand how open-source RAN software and collaborative testbed ecosystems could shape the future of wireless communications.
