Under this strategic partnership, Tata Elxsi is working with Sky to modernize network provisioning, cross-domain inventory and operations, improve service agility, and build a scalable foundation for autonomous networks. Central to this collaboration is Tata Elxsi’s NEURON platform portfolio, an AI-led suite of platforms designed to accelerate autonomous network transformation. By bringing together telco cloud lifecycle automation, multi-domain network engineering, service-aware inventory, and observability, NEURON enables communications service providers to streamline operations, improve agility, and advance towards Autonomous Networks. The NEURON platform portfolio comprises: • Telco Cloud Automation – End-to-end 4G/5G lifecycle management across Day 0 to Day 2 operations • Digital Network Engineering (DNE) – Multi-domain automation across metro, CDN, broadband, and ISP networks • Service-Aware Inventory (PlanNet) – Cloud-native, unified visibility across network and service domains Together, these capabilities enable standardization, intent-driven automation, and orchestration across hybrid and multi-domain environments, accelerating the journey toward autonomous networks. The deployment of the NEURON platform portfolio has been delivering measurable business outcomes for Sky, including: • Up to 30% improvement in operational efficiency through advanced automation • Enhanced cybersecurity and regulatory compliance by embedding automation across critical processes • Intent-driven automation and modernised network inventory, delivering 60–70% cost efficiencies • Reduction in network change lead times by up to 50%, accelerating service delivery • Reduction in network change failure rates by up to 30%, improving reliability from intent to deployment Laurent Lavallee, Group Director of Networks, Sky: “NEURON is helping to transform how our networks operate – improving visibility, simplifying processes and accelerating service delivery.

Across our engagements with telecom operators in Europe, the Middle East, and other global markets, we see a common set of challenges—legacy network environments, fragmented multi- domain inventory, and increasing cost pressures—driving a shift toward platform-led transformation. Our work with Sky demonstrates how NEURON provides a clear pathway to modernizing operations, automation at scale, improving efficiency, and enabling AI-led autonomous networks.” Tata Elxsi embeds AI across its platforms and services—enabling intelligent automation, predictive operations, and data-driven decision-making across the network lifecycle.
