5G infrastructure

The most meaningful 5G infrastructure theme this week is the continued shift toward 5G standalone (SA), cloud-native, and AI-assisted networks. Recent coverage shows that network operators and vendors pushing 5G SA expansion, automation, and private-network use cases, alongside funding and buildout activity in fiber and rural transport that support 5G coverage and capacity growth.

A few developments stand out from the available coverage:

Google Cloud and Nokia expanded their AI partnership for autonomous networks.
Ericsson and LG Uplus (Korea) agreed to deepen their strategic partnership to develop and expand network-based voice AI solutions for global markets, and advance AI-native network transformation.
KDDI (Japan) launched a RAN digital twin initiative.
CityFibre (UK) extended its 5G SA partnership with VodafoneThree (UK).
Microamp (Poland) won EU backing for a 5G mmWave AI-RAN platform.
There is also continuing momentum around mission-critical and industrial 5G, including Nokia Defense/KNDS tactical communications and Telia’s work on critical IoT and advanced 5G SA services.

It’s now crystal clear that 5G infrastructure investment is moving beyond raw radio deployment and into orchestration, automation, and vertical-specific network design. That is the bigger takeaway for telecom analysts: 5G spend is increasingly being justified by software intelligence, private/enterprise monetization, and operational efficiency rather than network coverage or speeds.

AI-Driven Network Management: Nokia vs. Ericsson vs. KDDI (2026):

An important structural caveat: Nokia and Ericsson are network equipment vendors whose AI tools are deployed across multiple operator customers, while KDDI is a mobile network operator deploying AI within its own live network. Direct comparisons of “commercial deployment” must account for this important distinction.

Comparison Table

Dimension	Nokia	Ericsson	KDDI
Role	Vendor	Vendor	Operator
Gemini Integration	Most advanced Gemini deployment. Six specialized Gemini-powered AI agents built into Nokia Assurance Center using Google Cloud ADK and Gemini Enterprise Agent Platform: Router (orchestration), Event Triage, KPI Selector, Anomaly Reasoner, Remediation, Dashboard Generation. Router and Triage agents already live in Nokia’s environment; full SaaS on Google Cloud Marketplace targeting September 2026, with additional agents rolling through 2027	No 2026 productized Gemini-agent stack comparable to Nokia’s found. Named Google Cloud Partner of the Year for Telecom (4th consecutive year). A 2025 demo showed Ericsson’s cognitive AI solution leveraging Gemini and Vertex AI for intent-driven orchestration, but this remains a collaboration/demo rather than a shipping product. Primary AI partnerships are with AWS and Mistral AI.	Gemini on Google Distributed Cloud (GDC) trial started March 2026 at Osaka Sakai Data Center, targeting commercial availability in 2027. Plans to use Gemini on GDC for a multi-agent system that automates network development from design through testing Strategic Google Cloud partnership (Oct 2025) for Gemini + Notebook

MoU with SK Telecom through 2031 (AI-RAN, 6G standardization); MoU with Chunghwa Telecom (5G-Advanced, AI-RAN, pre-6G); INTENTION 6G project (€12M+, France 2030, with Orange/BubbleRAN/CentraleSupélec); Apple + MediaTek 6G prototype demos at MWC 2026 including multi-RAT spectrum sharing (MRSS) for 5G-6G coexistence.	RAN Digital Twin as foundational platform for 6G era. “AI for Network” framework for autonomous network operations, maintenance, optimization, and security. Prototype by March 2028, commercial validation by FY2030. AI air interface technology for communication quality and power savings. KDDI’s AI data centers (AI factories) to serve as computing engine for RAN Digital Twin at scale (KDDI Research).

Network Layers Automated	Cross-domain service assurance (Nokia Assurance Center with Gemini agents — high-risk core changes require human sign-off); RAN (MantaRay SMO, AI-RAN, rApps, MantaRay SON); IP (NSP agentic AI); Optical (WaveSuite); Fixed/Broadband (Altiplano, Corteca, Broadband Easy); Security (zero-day attack detection in Agent Library)	RAN (AI in RAN, EIAP/rApps, AI-managed beamforming, AI-native scheduler); Core (EIAP expanding into core with cApps — fault prediction, traffic rerouting, capacity forecasting; core network digital twin); OSS/BSS (20+ Telco IT AI Apps on Telco IT AI Engine); Enterprise (NetCloud ANA agentic AI)	Core/Operations (Fault Recovery Support Agent for cloud-based voice/data/payment services; operational digital twin for fault analysis); RAN (multi-AI agent area optimization nationwide; RAN Digital Twin for 6G); Network Development (Gemini-powered multi-agent system for design-to-testing automation)
Deployment Maturity	Router and Event Triage agents live in Nokia’s environment (not yet deployed with operator customers); AI-RAN functional tests with multiple operators; MantaRay SMO ready for deployment at scale; du has achieved up to 20% energy savings in commercial 5G; Taiwan Mobile deal for AI-driven capabilities (July 2026); NOC operations serving global customers with 99.7% first-time-right rate	Most mature vendor-scale commercial deployment. EIAP adopted by AT&T, Swisscom, Telstra, Vodafone; #1 ranked by ABI Research for RAN automation platforms (Feb 2026); AI in RAN as a commercially scalable subscription; rApp aaS available on AWS Marketplace with field testing at Vivo Brazil; NetCloud agentic AI rolling out to enterprise customers; Google Cloud Partner of the Year.	Strongest operator own-network production evidence. Fault Recovery Support Agent live since Feb 2026 in commercial network; multi-AI agent area optimization deploying nationwide in FY2026 with confirmed 25% improvement in congested areas; Samsung RSO trial on live 5G SA network (407 sites, Tokyo); Gemini on GDC still in trial phase; RAN Digital Twin in early collaboration phase.

Furthest along at vendor/customer commercial scale: Ericsson. The strongest discriminator is deployed EIAP customer adoption (AT&T, Swisscom, Telstra, Vodafone), the ~90-rApp ecosystem with ~90 ecosystem members, and the scale of Ericsson’s AI network-optimization estate (100M+ daily AI inferences across 13M+ sites serving 2B+ subscribers). The #1 ABI Research ranking for RAN automation (February 2026), the commercially scalable AI in RAN software subscription (June 2026), and rApp aaS available on AWS Marketplace (February 2026) further solidify Ericsson’s position as the most commercially mature vendor. Ericsson also has the broadest pre-existing digital twin ecosystem, though its RAN digital twin assets are more fragmented across research initiatives, rApps, and site-level tools compared to Nokia’s unified product launch.

Furthest along as an operator using AI agents in its own live network: KDDI. KDDI’s Fault Recovery Support Agent has been live in commercial operations since February 2026, and its multi-AI agent area optimization technology is deploying nationwide across base stations in FY2026 with confirmed quantitative gains (25% improvement in congested areas, 95%+ reduction in optimization work). This is stronger “own-network production” evidence than Nokia’s or Ericsson’s vendor-side claims, because KDDI is demonstrating autonomous AI agents operating in a live commercial network rather than selling tools for others to deploy. However, KDDI’s RAN Digital Twin remains an early-stage collaboration (prototype target March 2028), and its Gemini on GDC integration is still in trial.

Furthest along in explicit Gemini integration: Nokia. Nokia has the most direct and productized Gemini integration of the three, with six specialized Gemini-powered agents built on Google Cloud’s ADK and Gemini Enterprise Agent Platform, two of which (Router and Event Triage) are already running in Nokia’s environment. However, these agents are not yet commercially deployed with operator customers — the full SaaS package targets Google Cloud Marketplace in September 2026, with additional agents shipping through 2027. Nokia also launched the clearest single RAN Digital Twin product (February 2026, NVIDIA AODT) and has the most explicit vendor-side Gemini story, but its commercial deployment footprint with operators is narrower than Ericsson’s.

Summary:

Ericsson leads in commercial scale and breadth, KDDI leads in live operator-network AI agent deployment, and Nokia leads in depth of Gemini integration and unified RAN digital twin productization.
