Quick Overview

At the India Mobile Congress (IMC) 2025, India hosted the 2nd International Bharat 6G Symposium, showcasing its leadership in next-generation telecom. Global alliances signed the New Delhi Declaration on 6G, outlining principles of trust, resilience, inclusivity, and sustainability. With the Bharat 6G Vision aligned to Viksit Bharat 2047, India aims for indigenous innovation, global collaboration, and a USD 1.2 trillion GDP impact by 2035.

Introduction

India’s pursuit of technological self-reliance took a major leap forward with the 2nd International Bharat 6G Symposium at the India Mobile Congress (IMC) 2025, Asia’s leading telecom technology event. The symposium marked a decisive stride in India’s ambition to build a self-reliant, inclusive, and future-ready 6G ecosystem, reinforcing its commitment to Viksit Bharat 2047.

Key Outcomes of the 2nd Bharat 6G Symposium

1. New Delhi Declaration on 6G:
Global research alliances including Bharat 6G, 6G-IA (Europe), and Next G Alliance (North America) signed a joint declaration positioning 6G as a global public good. The declaration identified five guiding principles—trust, resilience, openness, inclusivity, and sustainability—emphasizing global cooperation and skill development.

2. Economic and Innovation Goals:
India’s 6G roadmap envisions a USD 1.2 trillion GDP contribution by 2035, 10% of global 6G patents, and a threefold rise in satellite communications by 2033. The indigenous 4G stack showcased at the event reflects India’s growing R&D capacity and export readiness.

3. Collaboration and Inclusivity:
The symposium highlighted India’s transition from technology consumer to technology co-creator, underlining the need for industry–academia partnerships, indigenous R&D, and equitable access.

Bharat 6G Vision: Foundation for a Digital Future

Launched in 2023, the Bharat 6G Vision seeks to position India as a global co-creator in wireless communication, aligned with the objectives of Viksit Bharat 2047.

Key Components:

  • Bharat 6G Alliance (B6GA):
    An industry-led, government-supported consortium of telecom operators, startups, academia, and R&D bodies. With over 80 members, it collaborates globally with 6G alliances from the USA, Europe, South Korea, Finland, and Brazil.

  • Bharat 6G Mission:
    Focused on indigenous innovation, sustainability, and inclusivity, ensuring India’s contribution to the global 6G ecosystem by 2030.

  • Research Infrastructure:
    India has established the 6G THz Testbed and the Advanced Optical Communication Testbed, alongside 100 5G labs across academic institutions to create a 6G-ready innovation ecosystem.

  • Telecom Technology Development Fund (TTDF):
    Established in 2022 to support R&D for affordable rural connectivity, funding over 115 projects worth ₹310.6 crore as of 2025.

6G Technology: Overview

6G, formally known as IMT-2030 by the International Telecommunication Union (ITU), represents the next evolution in telecommunications.
It is expected to deliver data speeds up to 1,000 times faster than 5G, supporting real-time applications such as remote surgery, robotics, and immersive virtual environments.
Integration with AI will enhance network efficiency, predictive analysis, and security resilience.

Challenges in India’s 6G Readiness

  1. Infrastructure Limitations: Transition from 5G to 6G demands advanced semiconductors, dense fiber networks, and indigenous hardware capabilities.

  2. R&D Ecosystem Gaps: Private investment and patent output lag behind global benchmarks.

  3. Spectrum and Standards: Global uncertainty around THz frequency regulation may delay rollout.

  4. Talent Shortage: The need for expertise in AI, photonics, and network design remains pressing.

  5. Affordability & Digital Divide: High deployment costs risk deepening rural-urban disparities.

  6. Cybersecurity Concerns: Massive connectivity increases vulnerability to data breaches and misuse.

Way Forward: Strengthening India’s 6G Ecosystem

  • Promote Indigenous Manufacturing: Integrate 6G hardware and components under PLI schemes to enhance domestic capacity.

  • Skill Development: Expand telecom and AI-based education to prepare a 6G-ready workforce.

  • Spectrum Reforms: Develop a National Spectrum Strategy for THz frequencies and engage actively in ITU deliberations.

  • Inclusive Rollout: Align 6G with Digital India and BharatNet to ensure equitable access across regions.

Conclusion

The 2nd International Bharat 6G Symposium reinforces India’s transformation from a telecom adopter to a global innovator. Through the Bharat 6G Vision, strategic global alliances, and indigenous R&D initiatives, India is paving the way for a secure, inclusive, and technologically self-reliant telecom ecosystem. This progress underpins the broader ambition of achieving a digitally empowered Viksit Bharat by 2047.
