Why Open Source, and Why Now
Media and network technologies move fast, and open source usually arrives only after a standard is frozen, with additional cost at every stage along the way. The Accelerator closes both gaps.
Early feedback and validation
Implementation evidence that informs specification development before standards are finalised.
Software projects & Dev community
A community of standards experts, developers and implementers, building software projects together.
No duplication and fast deployment
Shared reference implementations mean no one builds the same thing twice.
Open by design and IPR-friendly
IPR-friendly licensing, designed from the start for broad industry participation.
Enabling open-source software from the start of every project
A specification is only valuable once it can be implemented, tested and deployed. Open source is the mechanism that makes it work.
Duplicated prototypes. Each organisation builds its own to evaluate a draft; results differ and feedback is slow.
One shared baseline. Drafts are validated against running code before the freeze, while gaps are cheap to fix.
Late interop bugs. Testing starts from scratch at plugfests; errors, some in the specification, surface late.
Faster plugfests. Implementers start from the same code: shorter preparation, faster root-cause analysis.
Slow deployment. Years can pass from a frozen specification to production-ready code; early adopters carry the cost alone.
Earlier deployment. End-to-end demos and trials run before commercial products, and feed evidence back into the standard.
We make open-source software and evaluation platforms work-plan deliverables, not optional extras
- Work item launch1Plan it at launch
Define the open-source software and evaluation platform track from day one: where the code lives, its scope, the evaluation metrics. Reuse existing open platforms.
- Drafting2Engage implementers during drafting
Involve open-source communities while the specification is written, and invest in that development. Running code surfaces issues that text review cannot.
- Freeze and deployment3Make the value tangible
End-to-end demos and benchmark platforms show that the standard works. They lower cost for the whole ecosystem: members and non-members alike, start-ups, academia.
In one line, for every new work item“Open-source software and evaluation platform: home and scope identified at launch.”

Protecting IPR. Enabling industry collaboration.
What is the License Model?
- The 5G-MAG Public License v1.0 is a modified version of Apache 2.0 which allows:
- Free Non-Commercial Use: freely use, copy, modify, and distribute the code for non-commercial purposes, including study, academic research, testing, and validation.
- Commercial Exploitation: use the reference tools and software within commercial services, trials, and live deployments, but with FRAND Patent Licensing: if used commercially, the built-in patent clause ensures that any essential contributor patents are made available under FRAND (Fair, Reasonable, and Non-Discriminatory) terms.
- Repositories with software derived from other licenses keep their own license according to their own terms.
How to Contribute?
- Sign an Individual or Corporate Contributor License Agreement (CLA).
- Anybody can become a contributor (no need to be a 5G-MAG member to contribute code).
- 5G-MAG members get priority in support from the 5G-MAG Project Office, and additional development resources may be provided. 5G-MAG members define priorities and where to dedicate resources.
- Membership of 5G-MAG remains open to the industry, to boost and scale your software project by joining forces.
