Open6GE

Evolving Open 5G and 5G-Advanced Towards 6G

An open evolution platform for integrating, experimenting, accelerating, automating, and validating emerging 6G technologies on today's open 5G and 5G-Advanced foundation.

Background

Why Open6GE exists

Open source has come a long way in 5G. There are solid projects for the radio network, the core, orchestration, simulation and cloud infrastructure, and each one does its job well.

What is missing is the network they add up to. Open6GE puts those projects together into one stack you can deploy, extend and test end to end, instead of a set of parts that only work on their own.

On top of that base, TOSSI is building the technologies 6G will need: AI-RAN, sensing and communication (ISAC), non-terrestrial networks (NTN), digital twins, accelerated computing, post-quantum security and intelligent automation. The hard part was never the components. It is making them work as one network.

The ecosystem

What Open6GE brings together

Open6GE brings together the tools, testbeds and technologies developed across the TOSSI ecosystem. From AI-RAN and NTN to ISAC, security, interoperability and certification, each capability addresses a different part of the transition towards intelligent, open and programmable 6G networks.

Technology areas

Ten areas of work

AI RAN Machine learning inside the RAN for scheduling, link adaptation and channel prediction.

Architecture

How the stack is layered

Four layers, each building on the one below. Upstream projects supply the components; the integration layer makes them interoperate; that foundation carries the 6G technologies; and the technologies enable the use cases.

Open and upstream

Openness and upstream work

Open foundation

Open6GE is not intended to become another closed telecom stack. It is built on open-source projects, open interfaces, and established industry standards. It provides a modular foundation that enables the community to integrate existing technologies, develop new capabilities, and contribute improvements back to the broader open-source ecosystem.

Upstream contributions

Contributions and enhancements are developed in alignment with upstream projects and the wider open-source community, rather than diverging from them.

An environment where the community can

  • Reuse existing open-source projects
  • Integrate technologies from different ecosystems
  • Experiment with emerging 6G capabilities
  • Build new components
  • Validate interoperability
  • Contribute improvements upstream
  • Create reproducible test environments
Roadmap

What exists today, and what comes next

Significant work remains before 6G becomes a commercial reality, and the specifications are not final. The environment needed to explore these technologies can be built before then, starting from what already works.
