Open RAN FAQs
What does Open RAN mean?
Open RAN stands for open radio access network. Specifically, Open RAN is an ongoing shift in mobile network architectures that enables service providers the use of non-proprietary subcomponents from a variety of vendors. Specific proprietary components like remote radio head (RRH) and baseband units (BBUs) are now disaggregated to centralized units (CU), distributed units (DU), and radio units (RU). With Open RAN, the new disaggregated functions can also be virtualized or containerized. The O-RAN Alliance takes it a step further by ensuring that the interfaces between these components are open and interoperable.
What is the benefit of Open RAN?
Open RAN helps service providers avoid vendor lock-in while encouraging vendor diversity. Service providers don’t want to deploy single-vendor solutions for their radio access networks, where equipment and software are provided by a single vendor. The Open RAN approach provides a clear path towards fully programmable, intelligent, and multi-vendor RAN with the help of a RAN Intelligent Controller (RIC).
What is a RIC and why is it needed for Open RAN?
A RAN Intelligent Controller (RIC) is a software-defined component of the Open RAN architecture that controls and optimizes RAN functions. The RIC is an important part of Open RAN disaggregation, bringing multi-vendor interoperability, intelligence, agility, and programmability to radio access networks. It enables the onboarding of third-party applications that automate and optimize RAN operations at scale while supporting innovative use cases that lower mobile operators’ total cost of ownership (TCO) and enhance customers’ quality of experience (QoE).
How does Juniper optimize Open RAN for users using RIC?
Juniper’s RIC platform extends our vision for automation, control, intelligence, and assurance to radio access networks. As a RAN-neutral vendor, Juniper’s approach is to create an open RIC platform that enables powerful rApps/xApps from Juniper as well as third parties, available in an Open RAN “app store.” This helps operators create new business models, personalize service experiences, and optimize CapEx and OpEx. Juniper’s solutions are architected with open interfaces on the northbound and southbound sides for easier integration with partner solutions in the Open RAN ecosystem.
