Open RAN: Transforming the Future of Mobile Networks

Breaking Away from the Old Vendor Model

For decades, mobile networks relied on tightly integrated vendor ecosystems, limiting flexibility and stifling innovation. Open RAN (Radio Access Network) is changing that. By separating hardware and software and establishing open interfaces, Open RAN enables operators to gain more control, improve agility, and broaden their supplier options.

Standards and the Role of the O-RAN Alliance

The O-RAN Alliance has been instrumental in defining technical standards that support interoperability, security, and modularity. Programs such as Plugfests and Open Testing and Integration Centers (OTICs) accelerate the validation and certification of Open RAN components, ensuring readiness for deployment at scale.

Open RAN in Action: From Concept to Deployment

What began as an idea is now taking shape in live networks. New players like Dish and Rakuten have rolled out fully virtualized, cloud-native architectures. At the same time, established operators such as AT&T, Vodafone, Telefónica, and Telus are integrating Open RAN into their existing infrastructures. The industry’s success hinges on three key imperatives:

1. Deployment at Scale

Large-scale roll-outs are the strongest proof of Open RAN’s viability. AT&T has pledged $14 billion over five years to migrate 70% of its wireless traffic to Open RAN by 2026. Similarly, Vodafone, Telefónica, and Telus have set ambitious targets to integrate Open RAN across their networks by 2030. Meeting these goals will establish Open RAN as a core part of the world’s telecom infrastructure.

2. Sustained Investment

The long-term future of Open RAN depends on continuous funding from both the private and public sectors.

In the U.S., the NTIA’s Public Wireless Supply Chain Innovation Fund has allocated $140M for testing (NOFO 1) and $400M for Open RAN radio unit development (NOFO 2).
In the UK, the Open Networks Programme is investing £295M (~$367M) to expand supplier diversity, with a target to route 35% of mobile traffic through open networks by 2030.

These investments are strengthening the resilience and diversity of the Open RAN ecosystem.

3. Innovation as the Core Driver

Innovation is where Open RAN creates lasting value. The RAN Intelligent Controller (RIC) introduces real-time, AI-driven optimization through xApps and rApps, giving operators the ability to dynamically adapt network performance.

Companies like Cohere, Aira, and AirHop are already delivering advanced solutions that enhance spectrum efficiency, reduce costs, and improve user experience. As the RIC ecosystem matures, it will play a central role in defining competitive advantage.

The Importance of Testing

With Open RAN, disaggregated components—O-RUs, O-DUs, O-CUs, and RICs—must work seamlessly together. That makes testing a critical part of deployment.

VIAVI has developed a comprehensive suite of Open RAN test solutions, including advanced RIC testing. The RAN Scenario Generator creates synthetic data to simulate real-world conditions, enabling developers to test and refine applications without risking live-user privacy. This accelerates development and ensures reliable network performance.

Why Open RAN Matters

Open RAN marks a turning point for the telecom industry. Its success will depend on:

Widespread deployment across global networks
Ongoing investment from both private and public sectors
Relentless innovation to drive efficiency and performance

With shared standards, robust testing frameworks, and strong collaboration, Open RAN is paving the way for a more open, flexible, and future-ready mobile network environment.
