Discuss how principles such as 'trust', 'openness' and 'sustainability' in the New Delhi Declaration on 6G reflect India's approach to digital public goods and secure supply chains.

At the International Bharat 6G Symposium 2025, global 6G alliances endorsed the New Delhi Declaration. It describes 6G as a "global public good" that should be secure, resilient, open, interoperable, inclusive and sustainable [1]. These principles follow India's wider digital approach: shared infrastructure that does not depend on a few vendors.

Trust: building secure supply chains

• Trusted networks: The Declaration roots 6G in "security… and trust" [1]. This works against vendor lock-in and untrusted suppliers in critical infrastructure.
• Diverse partners: The Bharat 6G Alliance (B6GA) now has 17 partnerships, including GSMA and one6G [2]. India and the EU have also reaffirmed cooperation on trusted telecom supply chains [3].
• Home-grown capacity: A Parliamentary Committee found India "greatly dependent" on imported telecom equipment [4]. The target of 10% of global 6G patents is meant to make India a contributor, not just a consumer [5].

Openness: the digital public goods approach

• Open, interoperable standards follow the logic of India's digital public infrastructure (UPI, Aadhaar). Open systems prevent any single player from controlling access.
• Shaping global rules: India hosted ITU-WTSA24, the first time the assembly was held in the Asia-Pacific [6]. The Declaration was co-signed by alliances from Europe, the US, Japan, Brazil and the UK [1].
• Shared knowledge: At the 2026 symposium, B6GA released nine white papers on topics such as integrated sensing and communication (ISAC) and spectrum readiness [2].

Sustainability and inclusion

• Green networks: The white paper "Sustainable 6G: Carbon Net Zero" addresses how much energy networks use [2].
• Affordable access: The Declaration promises that "no one is left behind" [1]. Fixed Wireless Access and Wi-Fi–cellular synergy are aimed at bringing connectivity to underserved areas [2].

Limitations

• Voluntary and self-reported: The Declaration is not binding, and its progress report is written by the alliances that signed it [2]. The binding rules are still made at 3GPP and the ITU.
• 5G gaps remain: Only about 30% of towers were fibre-connected, and spectrum reserve prices were called "exorbitantly high" [4].
• Limited funding: The Telecom Technology Development Fund (TTDF) has approved 115 projects on 5G and 6G worth Rs 310.6 crore [5]. That is modest for research meant to generate patents.

Overall, these principles combine India's model of open public digital infrastructure with its concern for strategic autonomy. To turn diplomatic goodwill into real influence, India should:

• measure results through Indian standard essential patents and proposals accepted at 3GPP;
• price spectrum affordably;
• extend production-linked incentives (PLI) to 6G hardware.

This would make 6G trusted, open and inclusive, in line with SDG 9 and India's goal of Vasudhaiva Kutumbakam in technology.
