  • Additionally, New Delhi plans to export its ‘India Stack — a set of digital public infrastructure tools for identity, data management, and payments — positioning itself as a key player in digital transformation for developing nations.

About 4G

  • It delivers high-speed internet, enabling HD video streaming and wireless broadband connectivity without wired ISP networks.
  • Technologies such as LTE, MIMO, and OFDM power 4G networks, offering higher bandwidth, lower latency, and improved efficiency.

India’s Indigenous 4G Technology Stack: A Step Toward Telecom Self-Reliance

  • India has achieved a landmark milestone by launching its first indigenously developed 4G network, featuring 98,000 Swadeshi 4G towers powered entirely by homegrown technology. 
  • The initiative — led by C-DOT (core network), Tejas Networks (radio access), and TCS (system integration) — marks a major stride towards Aatmanirbhar Bharat and digital self-reliance.
  • Previously reliant on foreign technology for 2G, 3G, and 4G, India built this stack from scratch during the Covid-19 pandemic, demonstrating resilience, innovation, and supply-chain independence. 
  • The BSNL 4G stack, designed to be cloud-native and 5G-ready, provides seamless connectivity and ensures easy future upgrades.
  • Complementary initiatives such as the Bharat 6G Alliance, Telecom Technology Development Fund, and 100 5G/6G labs are accelerating India’s journey toward Viksit Bharat 2047 and global digital leadership.

  • According to the Organisation for Research on China and Asia, this strategy forms part of China’s Digital Silk Road (DSR) — a key component of the Belt and Road Initiative aimed at expanding digital connectivity across the developing world.
  • The DSR promotes Chinese technology, goods, and services, including cellular networks, mobile apps, and payment platforms, while cementing China’s role as the global supplier of digital infrastructure
  • It represents a state–industry alliance, supported by policy banks and political backing, to strengthen China’s technological and geopolitical influence.
