O2-RAN

Orbital Open Radio Access Network

AI-Native Open RAN for Non-Terrestrial Networks & Space-Based Edge Computing

Advancing open, intelligent and resilient connectivity across satellite, aerial and terrestrial networks through joint communication, computation and energy-aware orchestration.

O²-RAN conceptual architecture across space, air and ground: GEO and LEO satellites, inter-satellite links, HAPS and UAV swarms, ground terminals, direct-to-cell and IoT connectivity, alongside distributed O-RAN control including xApps, rApps, SMO, RIC, CU-DU, RU and AI/ML frameworks.

Intelligent connectivity beyond terrestrial networks

Open, predictive, compute-aware communication across space, air and ground.

About O²-RAN

O²-RAN is a collaborative research project supported by the U.S. National Science Foundation (NSF) Directorate for Technology, Innovation and Partnerships (TIP) through its VINES Track 2 program. With $4.8 million in funding, the project is led by Farshad Firouzi of Johns Hopkins University. O²-RAN aims to advance 5G/6G satellite communications and in-orbit edge computing through an AI-native, compute-aware Open RAN architecture designed for non-terrestrial networks. Its research focuses on developing an end-to-end, NTN-adapted O-RAN hardware and software stack, encompassing L/S-band radio units, satellite payloads, distributed and central units (DU/CU), intelligent RAN controllers (RICs), service management and orchestration (SMO), and AI-driven computing and workload management. A central goal is to design, build, and launch an O²-RAN CubeSat into low Earth orbit, enabling experimental validation of satellite direct-to-cell connectivity, onboard AI processing, and space-based edge computing.

Beyond extending wireless coverage, O²-RAN seeks to transform satellites into programmable communication and computing platforms capable of hosting edge services and processing AI workloads directly in orbit. Through intelligent workload placement, AI-driven orchestration, and communication–computation co-optimization, the project advances in-orbit edge computing and future space-based data center capabilities, laying the foundation for open, interoperable, and resilient 5G/6G space–air–ground networks.
