Modular Radio Unit Design for Open RAN - A Vision for True Openness

Learn about the innovative approach to modular radio unit design in this 21-minute conference talk from Massive Beams CEO Andreas Benzin at the Open Compute Project Foundation. Explore how radio units in Open RAN, despite their specialized hardware requirements, can be built using modular components with defined interfaces. Discover the potential for scalable radio platforms that accommodate various RF bands, bandwidths, transmit powers, carriers, MIMO streams, TDD/FDD modes, and antenna ports through the use of interchangeable compute modules, motherboards, RF modules, front-end modules, and antennas. Gain insights into creating flexible, modular solutions for radio units while maintaining the necessary specialized processing capabilities required for digital-to-analog signal conversion and real-time digital signal processing.
