Responsibilities
On this page, we describe the responsibilities of the various organizations and projects that define different parts of the RAN ecosystem, including 3GPP, the O-RAN Alliance, ONF SD-RAN, and telecom infrastructure providers. The figure below provides an overview of these responsibilities.
Additionally, the table presents a comparison of these organizations and projects, highlighting their respective focus areas and roles within the RAN ecosystem.
| Layer / Component | 3GPP | O-RAN | ONF SD-RAN | Telecom Infra |
|---|---|---|---|---|

| Functional split (O-CU, O-DU, O-RU) | ✅ | |||
| Open interfaces (E2, A1, Fronthaul) | ✅ | ✅ | ||
| Network orchestration & automation | ✅ | |||
| Physical infrastructure (antennas, RU, fiber) | ✅ |
