The Bharat 6G Alliance and spectrum roadmap: what happened?
India’s 6G Vision needs spectrum planning, testbeds and standards work before commercial networks arrive. The Alliance is the industry-academia platform; DoT’s roadmap and the SAMEER testbed are the government tools named in this reply.
- A high data-rate line-of-sight link from the testbed project was shown at India Mobile Congress 2025.
- India pushed “ubiquitous connectivity” as one of six IMT-2030 (6G) usage scenarios at the ITU, plus coverage, interoperability and sustainability as capabilities.
- Stakeholders are being backed in 3GPP, ITU and oneM2M standardisation.
What is Bharat 6G Alliance?
- An industry- and academia-led society for domestic 6G research, innovation and IPR.
- It identifies technology gaps and develops testbed and research proposals aligned with India’s 6G Vision.
Why does the Bharat 6G Alliance and spectrum roadmap matter?
| Angle | What to note |
|---|---|
| Telecom | Spectrum roadmap and testbed for pre-commercial 6G work. |
| Standards | IMT-2030 inputs at ITU; 3GPP/oneM2M participation. |
| Industry | 90-member ecosystem across the stack. |
What are the challenges in the Bharat 6G Alliance and spectrum roadmap?
- Roadmaps and testbeds must still become standards wins and indigenous products.
- Spectrum decisions will need careful coexistence with existing services.
- Green 6G goals need measurable energy metrics, not only a working-group label.
What should be done next on the Bharat 6G Alliance and spectrum roadmap?
- Execute the SAMEER terahertz testbed on the three-year clock.
- Translate the spectrum roadmap into auction/allocation timelines.
- Keep Indian contributions flowing into ITU and 3GPP.
