Deutsche Telekom Switches to Mavenir for 5G Standalone Core

Deutsche Telekom made cloud jump from Ericsson to Mavenir in 5G
Deutsche Telekom's transition from Ericsson to Mavenir as its primary 5G standalone core provider represents a fundamental rethinking of how Tier 1 operators architect and operate networks in the cloud-native era. Mavenir now carries all standalone 5G traffic in Germany, while Ericsson handles legacy 4G and non-standalone 5G. Driven by the Horizontal TelCo Cloud initiative, the shift has already produced measurable results including 65% energy savings in live testing and three commercial network slicing deployments, with Apple FaceTime set to leverage these capabilities at consumer scale via iOS 26.

5G SA in Action: T-Mobile Prague Demos Enterprise-Ready Use Cases

5G SA in Action: T-Mobile Prague Demos Enterprise-Ready Use Cases
T-Mobile Czech Republic's Technology Innovations Day 2026 delivered live operational proof that 5G Standalone architecture is no longer a roadmap item. Running entirely on 5G SA infrastructure at the Magenta Experience Center in Prague, demonstrations spanned autonomous robotics, tele-surgery with military hospitals, AI-powered AR wearables, live field broadcasting, and quantum state transfer over existing fiber. For enterprise decision-makers evaluating private network investments or industrial automation strategies, the event confirmed that 5G SA now meets the reliability, latency, and isolation requirements of mission-critical operations across multiple verticals.

Deutsche Telekom telco cloud cuts 5G core energy by up to 65%

Deutsche Telekom telco cloud cuts 5G core energy by up to 65%
Deutsche Telekom’s early live results showing up to 65% energy savings in its 5G core spotlight a pragmatic path to cut opex and carbon as traffic surges and standalone 5G scales. Operators have wrung out much of the easy efficiency from hardware refreshes; the next gains come from software-driven, demand-aware control. DT is applying that logic to the core, shifting components to run only when needed rather than idling at full power. The results are enabled by DT’s “Horizontal Telco Cloud,” a unified, standards-based platform that replaces fragmented stacks with one common layer for core services. Initial live-network tests have been completed, with broader rollout planned and further detail expected at MWC Barcelona 2026.

KDDI & Nokia: Quantum-Safe Optical Transport for AI DCI

KDDI & Nokia: Quantum-Safe Optical Transport for AI DCI
KDDI and Nokia validated quantum-safe optical transport at KDDI’s new Sakai Data Center, a facility built to support real-time AI training, inference, and analytics. The demonstration used Nokia’s 1830 Photonic Service Switch with C+L band capabilities for capacity scaling and the 1830 Security Management Server for centralized key and policy control. The goal is clear: deliver high-throughput, low-latency, and line-rate encrypted data center interconnect (DCI) that is resilient against both today’s threats and tomorrow’s quantum-era risks. Encrypting at the optical layer removes the performance penalties of application or IP-layer encryption and avoids fragmenting security by workload.

Blackstone backs Neysa with $1.2B for India AI infrastructure

Blackstone backs Neysa with $1.2B for India AI infrastructure
Blackstone will take a majority stake in Neysa through up to $600 million in primary equity, alongside Teachers’ Venture Growth, TVS Capital, 360 ONE Asset, and Nexus Venture Partners; the company also plans up to $600 million in debt to accelerate buildout. The raise is a step change from Neysa’s earlier $50 million and positions the Mumbai-headquartered startup to scale domestic GPU clusters for enterprises, public sector agencies, and AI developers.

India AI data city: Vizag 6GW compute hub

India AI data city: Vizag 6GW compute hub
The plan centers on Visakhapatnam, a port city on India’s east coast, as a tightly coupled zone for data centers, subsea cable landings, power, water, and the digital supply chain. State leadership wants the cluster to be more than rack space. It aims to bring in server assemblers, power and cooling vendors, and specialized logistics to create end-to-end capability. The city is also being pitched as a landing point for new subsea systems toward Singapore, which would diversify India’s international connectivity beyond Chennai and Mumbai and lower latency into Southeast Asia.

Virgin Media O2 & Zinworks Uses AI for Mobile Network Monitoring

Virgin Media O2 Uses AI for Mobile Network Monitoring
Virgin Media O2 has broadened its partnership with Zinkworks to deploy AI-driven monitoring and automation across its mobile footprint, designed to spot anomalies earlier, resolve incidents faster, and prevent customer-impacting outages. The rollout targets multiple network domains and operational workflows, advancing the operator’s move toward autonomous operations with engineers maintaining full oversight. The capabilities span radio access, core network systems, and network operations centers, combining real-time telemetry with intelligent automation. The stack runs on Google Cloud and taps services such as Vertex AI and Gemini to analyze patterns, orchestrate responses, and augment decision-making for operations teams.

Deutsche Telekom Industrial AI Cloud in Munich

Deutsche Telekom Industrial AI Cloud in Munich
Deutsche Telekom and T-Systems have switched on a sovereign, NVIDIA-powered AI factory in Munich’s Tucherpark, positioning Germany as a serious contender in industrial AI infrastructure. The new facility brings nearly 10,000 NVIDIA Blackwell GPUs online, including DGX B200 systems and NVIDIA RTX Pro Server GPUs, delivering up to 0.5 exaFLOPS of AI compute for training, fine-tuning, and large-scale inference. Operated by T-Systems on German soil, the platform targets industry, research, startups, and the public sector with strict controls for data protection, security, and availability. Early customers include Agile Robots, which is combining vision, robotics, and foundation models, and PhysicsX, which applies AI to technical simulation.

NGMN’s 5G Network Simplification Framework

NGMN’s 5G Network Simplification Framework
NGMN’s latest operator-led guidance frames simplification as a precondition for 5G efficiency, sustainability and service agility—not an optional clean-up exercise. NGMN’s new Framework for Network Simplification – An Operator View argues for targeted simplification across radio, core and transport to contain this sprawl while preserving the ability to launch differentiated services. The alliance places cloud‑native design, federated service exposure and AI‑driven operations at the center of that shift, supported by agile ways of working. Simplification is how operators square the circle—cut carbon and cost, while accelerating innovation. The publication offers a practical, non-prescriptive method to decide where simplification delivers the most benefit, and when complexity risk outweighs near-term gains.

NVIDIA and Dassault Systèmes Launch Industrial AI Platform

NVIDIA and Dassault Systèmes Launch Industrial AI Platform
A long-term partnership between NVIDIA and Dassault Systèmes aims to make physics-grounded “world models” and virtual twins a mission-critical system of record for engineering, manufacturing, and the sciences. This collaboration moves beyond today’s project-level twin pilots toward industry-scale models that capture both geometry and behavior, validated against real physics and trusted industrial knowledge. The goal: use virtual environments not just to visualize, but to design, verify, and operate products and factories before steel is cut or code is deployed. The companies outlined a shared architecture spanning design, simulation, and operations.

AI-Driven Traffic Reshapes 5G Networks

AI-Driven Traffic Reshapes 5G Networks
The next wave of digital transformation will be defined by AI workloads riding on cloud and edge infrastructure over 5G networks, and that shift will change how networks are built, monetized, and secured. Generative and agentic AI move more compute into the network, creating persistent, uplink-heavy, low-latency flows rather than the mostly downlink, best-effort traffic of the smartphone era. Video from cameras, glasses, and sensors feeds models at the edge and in the cloud; results return in milliseconds to people and machines. That means tighter latency budgets, deterministic jitter control, and stronger guarantees for both throughput and reliability.
