4G Stack Latest News
- PM Modi, at the India Mobile Congress 2025, announced that India’s indigenously developed 4G stack would not only enhance connectivity and internet access within the country but also be exported globally.
- The 4G stack, comprising both telecom hardware and software, is part of India’s strategy to challenge China’s dominance in building telecom infrastructure across the developing world, especially in Africa.
- Though less advanced than Chinese systems from Huawei and ZTE, India aims to expand its footprint through affordable, secure, and locally developed solutions.
- 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
- 4G (fourth-generation wireless) represents the broadband mobile communication standard that succeeded 3G and paved the way for 5G.
- 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.
Key Features of India’s 4G Stack
- End-to-End Indigenous Stack: Combines Tejas Networks’ Radio Access Network, C-DOT’s Core Network, and TCS integration, cutting reliance on foreign vendors.
- Cloud-Native Software Architecture: Enables scalability, rapid upgrades, and smooth migration to 5G.
- Future-Proof Design: The network is 5G-ready, allowing upgrades without replacing existing infrastructure.
- Nationwide Reach: Deployed across 92,000+ sites, bringing connectivity to 22 million citizens, including tribal and remote areas.

India’s 4G Export Plan as a Response to China’s Digital Silk Road
- For years, China’s telecom giants like Huawei and ZTE have dominated developing markets by offering low-cost telecom infrastructure, backed by state funding and easy loans.
- 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.
