To take full advantage of cloud computing, the RAN needs all compute elements deployed in the cloud. This is RAN-in-the-Cloud — a 5G radio access network fully hosted as a service in multi-tenant cloud infrastructure running as a containerized solution alongside other applications. These can be dynamically allocated in an E2E stack to increase utilization and reduce CapEx and OpEX for telecom operators while allowing monetization of new edge applications and services, such as AI.

Aarna Networks provides an open source O-RAN SMO (service management and orchestration) built for easy integration across other O-RAN software components, such as RIC (RAN intelligent controllers), xApps, and rApps optimized and ready for RAN-in-the-Cloud deployments. This Proof-of-Concept includes a single pane of glass orchestrator from Aarna and Radisys.

In the U.S. alone, moving half of the total 420K cell sites to RAN-in-the-Cloud could result in multi-billion dollar revenue opportunities.
