Meta’s Evenstar is transitioning to OCP to accelerate open RAN adoption

Meta is transferring its IP for Evenstar, a program to accelerate the adoption of open RAN technologies, to the Open Compute Project (OCP). This includes contributing Evenstar's radio unit design, firmware, design files, and test scripts to OCP, making it the industry's first open, white box radio unit solution. The design features an advanced 4T4R MIMO transceiver, a modular architecture for mixing and matching components from different suppliers, and relies on off-the-shelf discrete components for lower BOM cost and independent control of power amplifier modules. The firmware handles complex signal processing algorithms like digital pre-distortion (DPD) and crest factor reduction (CFR). This contribution aims to accelerate open RAN commercialization by enabling the ecosystem to build modularized and efficient radio unit platforms.
