Why AI matters at this scale

Altiostar, a Rakuten Symphony company, provides cloud-native, Open RAN (O-RAN) software that enables mobile network operators to build open, virtualized, and intelligent 4G and 5G networks. By disaggregating hardware from software, Altiostar's platform allows operators to mix and match best-of-breed components, breaking vendor lock-in and accelerating innovation. The company's solutions are pivotal in the global shift towards more flexible, cost-effective, and automated mobile network infrastructure.

For a company of Altiostar's size (1001-5000 employees), operating at the enterprise level within the capital-intensive telecom sector, AI is not a luxury but a core competitive necessity. At this scale, the complexity of managing software-defined networks across thousands of sites and multiple vendors becomes unmanageable with human-led operations alone. AI provides the essential toolset for automation, predictive analytics, and real-time optimization, translating directly into massive operational expenditure (OpEx) savings, improved customer quality of experience, and the ability to offer new, intelligent network services. The backing and tech-centric culture of Rakuten Symphony further amplify the resources and mandate to invest in advanced AI/ML capabilities.

Concrete AI Opportunities with ROI Framing

1. Autonomous Network Optimization: Deploying AI agents that continuously analyze radio access network (RAN) performance data (e.g., signal strength, interference, user equipment reports) to automatically adjust tilt, power, and handover parameters. This can improve spectral efficiency by 15-30%, directly increasing network capacity without adding physical towers—a major CapEx deferral.

2. Predictive Maintenance and Fault Management: Machine learning models trained on historical network alarm and performance data can predict hardware failures or software anomalies days before they cause service degradation. For a large network, reducing mean-time-to-repair by even 20% can prevent millions in lost revenue from outages and slash truck-roll dispatch costs.

3. Dynamic Energy Management: AI can orchestrate the deep sleep modes of radio units and data center resources based on predicted traffic patterns, potentially reducing the RAN's energy consumption—which constitutes ~80% of a carrier's power bill—by 20-25%. This offers a direct, substantial OpEx reduction and supports sustainability goals.

Deployment Risks Specific to This Size Band

At the large-enterprise scale, key risks include integration sprawl, where AI initiatives become siloed within different product units (e.g., core network vs. RAN teams), leading to duplicated efforts and incompatible data models. Data governance is a monumental challenge; establishing a unified, clean, and real-time data pipeline from thousands of heterogeneous network elements across customer deployments requires significant cross-functional coordination and investment in data engineering. Finally, there is the skill gap risk; while the company can afford to hire AI talent, integrating these specialists into the deeply specialized domain of telecom networking requires extensive time and training to achieve true effectiveness, potentially slowing initial time-to-value.
