Software-defined Radio (SDR), Artificial Intelligence (AI), and Cloud Computing enable the transition of network functions from dedicated hardware to virtualized and cloud-native software components.

OC-RAN, developed by O-CRN, is a fully containerized, 3GPP & O-RAN-compliant Radio Access Network built using Software-Defined Radio, AI, and cloud-native technologies. It replaces traditional, hardware-bound RAN components with scalable software modules, enabling flexible, cost-efficient deployments. Supporting both O-RAN Split 7.2x and Split 8, OC-RAN is designed to run over open interfaces and can handle multiple fronthaul split configurations simultaneously.

• OC-RAN-CU (Central Unit)

  • Implements PDCP and RRC layers.
  • Fully containerized and cloud-native.
  • Supports deployment in public or private clouds.
  • Offers high availability and auto-recovery in case of failure.
  • Manages multiple DU with the same type of latencies that a standard S1 radio could support today.
  • Designed for scalability, reliability, and seamless orchestration.

• OC-RAN-DU (Distributed Unit)

  • Implements RLC, MAC, and High PHY layers.
  • Typically deployed at cell sites or edge data centers.
  • Optimized for low-latency fronthaul and high-performance radio processing.

OC-RAN is highly adaptable and supports a variety of deployment models

• CU in public cloud, DU at the edge.

• CU in data center, DU at the cell site

• CU and DU both in central or edge data centers.

• CU and DU co-located on the same server for compact deployments.
