At GTC 2025 in San Jose, Ronnie Vasishta, SVP of Telecommunications at NVIDIA, outlined the company’s vision for a sweeping transformation of the telecom industry—one powered by AI-driven infrastructure and agent-based automation. In a presentation that blended technical insights with real-world case studies, Vasishta framed this moment as a pivotal turning point, calling it the beginning of a “Telco AI Renaissance.”
NVIDIA’s journey into telecom AI has accelerated rapidly. Vasishta revealed that 90% of the world’s top 50 telcos are already deploying AI tools to modernize operations, improve customer experiences, and unlock new revenue streams. NVIDIA is partnering with more than 150 global telcos, pushing AI beyond just service optimization and into the heart of next-generation network architectures like AI-RAN and AI Factories.
One of the key highlights of the presentation was the application of agentic AI—AI systems capable of autonomous decision-making and collaboration within telecom environments. Vasishta showcased how partners like SoftBank and Indosat Ooredoo Hutchison are already leveraging NVIDIA’s NeMo framework and inference microservices (NIMs) to automate complex network management tasks that traditionally took days, now completed in minutes.

NVIDIA is also enabling telcos to become regional AI infrastructure leaders. Through the NVIDIA Cloud Partner Program (NCP), telcos like TELUS, Telenor, and IOH are standing up sovereign AI Factories that power workloads in healthcare, research, and enterprise applications—all while keeping data within national borders. At the infrastructure level, Vasishta emphasized the convergence of AI and RAN, detailing how AI-RAN architectures—running on NVIDIA’s Aerial platform—will fundamentally improve spectral efficiency, reduce costs, and prepare telcos for AI-native 6G networks.
