Ericsson Showcases 5G Core SaaS Innovation at MWC 2026

Why It Matters

The demonstration validates public‑cloud viability for carrier‑grade 5G cores, offering operators scalable, cost‑efficient infrastructure and faster service innovation.

Key Takeaways

• 1 Tbps 5G core runs on Google Cloud.
• Supports 1 million concurrent subscribers in public cloud.
• Elastic scaling via GKE reduces cost and complexity.
• AI-driven telemetry optimizes traffic and energy use.
• Trials underway; commercial launch slated soon.

Pulse Analysis

The telecom industry is accelerating its migration from on‑premise hardware to public‑cloud platforms, and Ericsson’s 1 Tbps 5G Core showcase underscores that shift. By moving core network functions to Google Cloud, operators gain access to a global fiber backbone and the elasticity of Kubernetes, allowing them to provision capacity in minutes rather than months. This flexibility is especially valuable as data‑intensive services such as fixed wireless broadband and massive IoT proliferate, demanding rapid scaling without massive capital expenditures.

Technically, the Ericsson‑Google partnership combines GKE‑driven auto‑scaling with AI‑powered telemetry that predicts traffic spikes and fine‑tunes resource allocation in real time. The result is a core that can “right‑size” itself, expanding to meet peak demand and contracting during lull periods, which translates into lower energy consumption and operational overhead. Integrated security tools native to Google Cloud further enhance the network’s resilience, addressing a long‑standing concern about moving carrier‑grade workloads to shared infrastructure.

From a market perspective, the successful trial signals that service providers can confidently adopt a consumption‑based model for their most critical network functions. As Ericsson prepares to roll the SaaS offering to commercial customers, operators worldwide will likely accelerate deployments for enhanced mobile broadband, voice, and IoT use cases. This could reshape vendor‑operator dynamics, push competitors toward similar cloud‑native solutions, and ultimately drive faster innovation cycles across the 5G ecosystem.
