Discover how PM Narendra Modi is set to launch India’s first indigenous 4G network in 2025, a milestone in telecom self-reliance. Learn about BSNL’s Swadeshi 4G stack, its impact, and what it means for India’s digital future.
Introduction to India’s Indigenous 4G Network
On September 27, 2025, Prime Minister Narendra Modi will unveil India’s first fully indigenous 4G network, a landmark step for the nation’s telecom sector. Spearheaded by Bharat Sanchar Nigam Limited (BSNL), this “Swadeshi” 4G network stack makes India one of just five nations—alongside Denmark, Sweden, South Korea, and China—to independently develop such telecom infrastructure.
This article explores what the indigenous 4G network is, the journey behind its creation, and its implications for India’s digital future.

What is the Indigenous 4G Network?
A Fully Indian-Made Telecom Solution
The indigenous 4G network is a cloud-based, 5G-upgradeable telecom stack designed entirely by Indian organizations. Unlike earlier networks dependent on foreign technology, this one represents India’s technological self-reliance.
- Core Software: Developed by the Centre for Development of Telematics (C-DOT).
- Radio Access Network (RAN): Built by Tejas Networks.
- Integration: Managed by Tata Consultancy Services (TCS).
The system will be deployed across 98,000 sites nationwide, ensuring coverage even in remote areas. The official launch at Jharsuguda, Odisha, will coincide with simultaneous rollouts in states like Uttar Pradesh and Jammu & Kashmir, symbolizing inclusive digital progress.
Achieving 100% 4G Saturation
Alongside the launch, PM Modi will also announce the completion of 100% 4G saturation under the Digital Bharat Nidhi initiative (formerly USOF). This has already connected 29,000–30,000 villages, ensuring high-speed internet reaches India’s remotest corners.

The Journey to Self-Reliance in Telecom
Overcoming Challenges
The indigenous 4G project faced early setbacks. In 2022, an initial test for 10,000 users failed, raising doubts over scalability. But within 22 months, engineers transformed the system into a “blockbuster” success. Collaboration between C-DOT, Tejas Networks, and TCS proved critical in achieving global standards.
Why It Matters
India has long depended on foreign telecom equipment, creating strategic vulnerabilities. With its indigenous 4G network, India now strengthens national security, reduces dependency on imports, and nurtures local innovation. Union Telecom Minister Jyotiraditya Scindia hailed it as a “moment of pride,” positioning India as the fifth country globally with full-stack telecom manufacturing capability.
Impact on India’s Digital Future
Boosting Connectivity
BSNL’s rollout of the indigenous 4G network will vastly improve connectivity across cities, towns, and villages. With 5G-readiness built into the system, the network will ensure a seamless transition as India’s telecom market expands. By 2028, India is projected to have 770 million 5G users, making it the world’s largest telecom base.
Economic and Strategic Benefits
The indigenous 4G stack promotes local manufacturing, creates skilled jobs, and strengthens the domestic tech ecosystem. Strategically, it shields India from global supply chain risks while ensuring digital access for marginalized communities through the Digital Bharat Nidhi program.
Global Significance of India’s Achievement
Joining the Elite Club
With this launch, India joins a select group of nations capable of building advanced telecom solutions. The achievement enhances India’s technological stature, placing it alongside global players like Nokia and Ericsson.
A Model for Other Nations
As the world’s largest telecom market, India’s indigenous 4G network offers a model for other developing nations. It proves that strategic investment in homegrown technology can transform connectivity and accelerate digital inclusion.
What to Expect from the Launch
Event Highlights
The September 27 event in Jharsuguda will feature:
- Official Unveiling of BSNL’s 4G services.
- Simultaneous Rollouts across multiple states.
- Digital Bharat Nidhi Announcement marking 100% rural 4G coverage.
Public and Industry Response
Industry leaders and citizens alike are calling this a “historic leap.” On social media platform X, hashtags such as #Swadeshi4G and #DigitalBharat are already trending.
Conclusion: A New Era for Indian Telecom
The launch of the indigenous 4G network is more than a technological milestone—it is a statement of India’s growing self-reliance and innovation capacity. With BSNL rolling out its Swadeshi 4G stack at 98,000 sites, India is set for a 5G-ready future while ensuring digital inclusion for all.
This achievement not only secures India’s telecom independence but also positions the country as a global leader in digital infrastructure.
