AT&T has deployed the world’s first third-party rApp on a live production network, marking a major milestone in the telecom industry’s transition toward open RAN architectures. The deployment, powered by Ericsson’s Intelligent Automation Platform (EIAP), optimized AT&T’s network in July following extensive testing and validation. The move demonstrates the maturity of the rApp ecosystem and confirms the viability of open standards, specifically the R1 interface, which connects rApps to Service Management and Orchestration (SMO) platforms.
The achievement represents a shift away from traditional, closed Self-Organizing Network (SON) systems toward an open, multi-vendor model where communication service providers (CSPs) can integrate automation applications from different developers. Ericsson’s EIAP ecosystem already includes over 60 CSP and developer partners and showcases more than 60 rApps in its directory, positioning it as a leading marketplace for network automation innovation. The deployment underscores how standardized interfaces enable CSPs like AT&T to adopt best-in-class tools while stimulating broader industry collaboration.
By enabling third-party automation in live networks, AT&T and Ericsson highlight the growing trust in programmable network functions. This step strengthens the Open RAN vision, giving operators flexibility to tailor and enhance network performance while reducing vendor lock-in. It also sets the stage for new forms of efficiency and agility as mobile networks scale to meet future 5G and beyond demands.
- AT&T becomes the first CSP globally to deploy a third-party rApp on a live network
- The rApp optimized AT&T’s production RAN in July 2025, leveraging Ericsson’s EIAP platform
- Deployment used the Open RAN Alliance–defined R1 interface for interoperability
- Ericsson’s rApp ecosystem includes 60+ members and 60+ automation applications
- Marks shift from closed SON systems to open, programmable RAN automation
Rob Soni, VP of RAN Technology at AT&T, said: “This milestone represents a significant leap forward in our commitment to openness and collaboration. By embracing third-party innovation on our network and platform, we’re signaling that diverse solutions play a key role in the future of commercial networks. We look forward to seeing the new levels of innovation, agility, and efficiency that programmability will unlock.”
🌐 Why it Matters: The deployment demonstrates real-world progress toward Open RAN’s promise of openness and interoperability, showing that rApps can securely influence live networks. This could accelerate a more competitive vendor ecosystem, reduce reliance on single suppliers, and spark rapid innovation in RAN automation tools across the industry.
What are rApps?
rApps (RAN automation applications) are software modules that run on Service Management and Orchestration (SMO) platforms to automate and optimize functions in mobile radio access networks (RAN). They use the standardized R1 interface defined by the O-RAN Alliance to communicate with the SMO and influence the network.
Unlike traditional Self-Organizing Networks (SON), which were typically tied to a single vendor’s equipment, rApps are built on open, standardized interfaces. This allows communication service providers (CSPs) to:
- Mix and match best-in-class automation applications from multiple developers
- Automate RAN functions such as load balancing, interference mitigation, and energy efficiency
- Deploy innovation faster through a growing ecosystem of third-party developers
- Reduce vendor lock-in by enabling interoperability across multi-vendor networks
In essence, rApps bring “programmability” to mobile networks, allowing CSPs to continuously adapt network performance in real time and prepare for new use cases in 5G and beyond.
Ericsson’s Role in rApps Development
Ericsson has taken a leading role in commercializing rApps through its Intelligent Automation Platform (EIAP), which serves as both an SMO and a marketplace for third-party applications. Some highlights:
- rApp Ecosystem Growth: Ericsson has built the industry’s largest rApp ecosystem, with over 60 partners(CSPs, developers, and vendors) and a directory of 60+ rApps available for deployment.
- Developer Enablement: EIAP includes SDKs, APIs, and testing tools so developers can build, validate, and publish rApps that are interoperable across networks.
- Multi-vendor Focus: EIAP supports 4G and 5G RANs across multiple vendors, advancing the Open RAN principle of openness.
- Commercial Deployments: With AT&T’s July 2025 deployment, Ericsson became the first vendor to demonstrate a third-party rApp influencing a live CSP production network.
Ericsson positions rApps as the next phase of network automation, complementing xApps (which operate closer to the near-real-time RAN Intelligent Controller, or RIC). While xApps focus on real-time optimizations like handover decisions, rApps target non-real-time functions such as planning, analytics, and long-term optimization.
