Government-backed Bharat 6G Alliance along with nine international bodies have signed the Delhi Declaration, which endorses principles for 6G ecosystem including the commitment to make it secure, open, resilient, inclusive, and sustainable by design.
The Delhi Declaration was announced at the International Bharat 6G Symposium 2025 held at India Mobile Congress 2025.
"As 6G research accelerates worldwide, this declaration underscores our collective responsibility to develop trusted technologies, open standards, and sustainable networks. India's leadership through Bharat 6G Alliance reflects our vision for an inclusive digital future. The Bharat 6G Alliance is proud to stand with global 6G alliances in endorsing these shared principles," Bharat 6G Alliance Director General R K Pathak said.
The NextG Alliance, 6G Smart Networks and Services Industry Association, Finland's 6G Flagship of Oulu University, South Korea-based 6G Forum, 6G Brasil, Next Generation Mobile Networks Alliance (NGMN), Germany-based 5G Alliance for Connected Industries and Automation (5G-ACIA), UK India Future Networks Initiative (UKI-FNI), UK Telecommunications Innovation Network (UKTIN), Japan's XG Mobile Promotion Forum, ESA Europe and India's TSDSI and Nasscom are part of the Delhi Declaration.
"Global research alliances "Bharat 6G, 6G Smart Networks and Services Industry Association (6G-IA), ATIS' Next G Alliance, XGMF, 6G Forum, 6G Brazil, UKI-FNI, UK TIN, UK Federated Telecoms Hubs (CHEDDAR, HASC, JOINER & TITAN), and 6G Flagship came together to issue a joint statement reaffirming a shared commitment to shape the future of 6G as a global public good," an official statement said.
The joint statement promotes open interfaces, multi-vendor interoperability, and AI-enabled network orchestration to accelerate innovation and affordability.
"Solutions must remain affordable and accessible, leveraging economies of scale and innovative financing models to support social sustainability. 6G must bridge digital divides, delivering reliable and affordable coverage and consistent user experience across urban, rural, and remote regions," the statement said.
The declaration places sustainability at the heart of 6G design, calling for energy-efficient, repairable, and recyclable systems that reduce carbon footprints while ensuring affordability and accessibility.
It envisions end-to-end global coverage through the integration of terrestrial and non-terrestrial networks satellites, high-altitude platforms, and future space-based systems -- to deliver seamless connectivity across land, sea, air, and space.
The declaration calls for open interfaces and multi-vendor interoperability across terrestrial and non-terrestrial hardware, software, and cloud-native platforms -- a move that will allow smaller and new vendors to become part of the telecom networks which at present is dominated by proprietary technologies.
The declaration, however, calls for respecting intellectual property rights.
"Standards must be developed in open, transparent, impartial, and consensus-driven forums with equitable participation across nations, regions, and stakeholder groups.
"Technical specifications must promote interoperability, resilience, openness, and competition, and respect intellectual property rights while driving accessibility and innovation," the declaration said.
The declaration calls for an international collaboration on research and development, testbeds, and pilot deployments to accelerate breakthroughs in performance, security, and affordability.
