6G calls for global alignment
The mobile industry is already looking beyond 5G. While 5G is still expanding, discussion around 6G continues to grow. Industry leaders now agree that global alignment must start early to avoid past mistakes.
The Next Generation Mobile Networks Alliance stresses that cooperation across regions will be critical. Strong alignment will help build secure, efficient, and sustainable digital infrastructure for the next decade.
From 5G to early 6G planning
6G is expected to shape communications in the 2030s. The 3GPP, which sets global mobile standards, plays a central role in this work.
Release 20 marks an important step. It completes key improvements for 5G Advanced and sets the technical base for 6G. In 2025, 3GPP finalised Stage 1, which defines early 6G service needs. Now, in 2026, work moves into Stage 2, which focuses on 6G architecture.
As a result, the industry has reached a turning point. Decisions made now will define how future networks evolve.
What the industry wants from 6G
The focus has shifted toward clear user value. Operators want more than faster speeds. They want simpler networks, lower energy use, and smooth migration from 5G to 6G.
At the same time, new challenges must be addressed. These include AI growth, quantum security risks, and network resilience. All now sit at the center of 6G discussions.
Operator priorities for the next generation
Mobile operators, vendors, and researchers must agree on a shared direction. Their goal is simple. New technology should benefit users, operators, and the wider ecosystem.
6G should build on 5 G’s strengths and correct its weaknesses. Migration must stay simple. Operators want fast rollout and stable service. Native voice support should exist from day one.
In addition, 6G should support new services without forcing mass hardware upgrades. This approach protects investment and supports long-term sustainability.
Deployment and performance expectations
New radio equipment will be needed for the new frequency bands. However, upgrades in existing bands should rely mainly on software. This ensures a smooth transition.
Any new 6G radio technology must show clear gains. At a minimum, it should exceed the performance of 5G Advanced as defined in Release 18. Without this proof, adoption will slow.
Drivers behind 6G evolution
Every new technology brings cost and risk. Therefore, the industry must weigh benefits against impact.
Efficiency stands out as a key goal. Operators want simpler operations, better spectrum use, and lower energy demand. Network exposure also matters. It enables developers to build services that match real market needs.
As a result, modular design, flexibility, and openness have become core drivers for 6G.
Requirements for future networks
Future networks must support wider social goals. They must protect the environment, remain affordable, and earn user trust.
Sustainability must guide design choices. This includes reducing emissions, supporting economic growth, and acting responsibly across the supply chain.
Security also plays a central role. Privacy and protection must be built into the system from the start. 6G should adopt quantum-safe methods and zero-trust principles to improve resilience.
Innovation with real-world value
Innovation remains important, but it must meet real needs. Any new radio interface should clearly outperform IMT 2020, the global 5G standard.
At the same time, designs must consider cost, deployment reality, and long-term impact. Backward compatibility with 5G remains essential.
6G will also link connectivity, AI, sensing, and computing. Networks must support AI, and AI must help run networks. Both sides depend on each other.
AI and network design
AI continues to advance at speed. Its influence will extend well beyond 6G.
Networks for AI will use AI to manage and optimise operations. AI for networks means building systems that support AI-driven services and workloads.
Because of this, architects must study AI trends closely. 5G suffered from complexity. To avoid repeating that, 6G must keep simplicity at its core from day one.
Why global alignment matters
Global coordination remains critical. Without it, networks fragment, costs rise, and innovation slows.
6G standards must align worldwide. This ensures compatibility, trust, and efficient deployment.
The NGMN Alliance plays a leading role here. As an operator-led group, it brings the industry together. It offers guidance and defines shared priorities early in the process.
With major milestones approaching, NGMN provides a clear path forward. It reflects operator needs and helps shape sustainable, affordable next-generation networks.
