The project aims to connect over 26,700 previously unconnected villages, including 2,472 in Odisha, many located in remote, border, and left-wing extremism-affected areas.
The launch, coinciding with BSNL’s silver jubilee celebrations, places India in an exclusive group of nations—including Denmark, Sweden, South Korea, and China—that manufacture their own telecom equipment. BSNL will complete 25 years of service on October 1, 2025.
Previously dependent on foreign technology for 2G, 3G, and 4G, India responded to the Covid-19 pandemic by building a fully indigenous 4G stack from scratch—demonstrating resilience, rapid innovation, and supply-chain independence, the Communications Ministry added.
On Saturday, Prime Minister Modi said BSNL’s 4G stack embodies the swadeshi spirit as he inaugurated India’s fully indigenous 4G stack and more than 97,500 BSNL towers from Jharsuguda, Odisha.
Responding on September 27, 2025, to a post by Union Minister Jyotiraditya Scindia on X, which shared an article titled ‘How BSNL’s 4G Stack Embodies the Swadeshi Spirit,’ PM Modi said: “Union Minister Scindia highlights how BSNL’s 4G stack embodies the swadeshi spirit. With over 92,000 sites connecting 22 million Indians, it reflects India’s journey from dependence to confidence, driving employment, exports, fiscal revival and advancing the vision of Aatmanirbhar Bharat.”
According to the Ministry, this achievement places India among only five nations capable of launching fully homegrown 4G services. “BSNL’s cloud-native, 5G-ready 4G stack ensures immediate connectivity while enabling seamless upgrades, nurturing domestic talent, and strengthening supply chains. Complementary government initiatives, including the Bharat 6G Alliance, 100 5G/6G labs, and the Telecom Technology Development Fund are advancing research and innovation, charting a path toward Viksit Bharat 2047 and global leadership in digital technology,” the statement read.
At a press conference on September 26, ahead of the launch of nationwide Swadeshi 4G (5G-ready) network, Minister Scindia explained the impact: “What does this signify for the common citizen? It means that students in Bihar will now have seamless access to world-class online education. Farmers in Punjab will receive real-time updates on Mandi prices. Soldiers stationed in Kashmir will remain connected with their loved ones. Entrepreneurs across the North East will be empowered with access to international expertise and funding. This 4G infrastructure is thoughtfully designed to uplift every Indian, regardless of their geography or background.”
He further added, “We are also unveiling India’s 100 percent 4G saturation network through Digital Bharat Nidhi(DBN), where close to 29,000 villages have been connected as part of the 4G saturation project and other projects of DBN, this comes ahead of BSNL’s silver jubilee, 25 years of service to the nation.”
Secretary of Telecom Neeraj Mittal made a presentation and highlighted India’s remarkable telecom growth story, tracing the journey from initial scepticism to the successful development of an indigenous 4G stack and the deployment of Swadeshi 4G towers across the country.
“India now stands at the cusp of a defining moment in global telecommunications. What seemed impossible just four years ago has now been made a reality through focused execution and unwavering commitment to the Prime Minister’s vision of self-reliance, digital inclusion, and global leadership. That vision is now taking tangible form. Today, India is not only expanding high-quality telecom services to 1.2 billion people, but also establishing itself as a global hub for telecom equipment manufacturing. This dual achievement reinforces the country’s role as a driver of global growth, equity, and digital inclusivity—an embodiment of Vasudhaiva Kutumbakam (the world is one family),” the Ministry said.
What is 4G?
4G is the short name for fourth-generation wireless, the stage of broadband mobile communications that supersedes 3G (third-generation wireless) and is the predecessor of 5G (fifth-generation wireless). With 4G download speeds, wireless users can stream high-definition video and audio.
4G also enables wireless broadband, allowing internet access without a fixed wired connection from an Internet Service Provider (ISP). It leverages technologies such as LTE, MIMO (Multiple Input Multiple Output), and OFDM (Orthogonal Frequency Division Multiplexing) to improve bandwidth, enhance efficiency, and reduce congestion.
BSNL 4G services to Benefit Remote Regions
The Communications Ministry said BSNL’s indigenous 4G services are expected to benefit tribal regions, remote villages, and hilly areas by providing access to quality digital services. This will enable children in rural areas to attend online classes, farmers in distant locations to check crop prices, and patients to consult doctors through telemedicine. Additionally, the initiative will greatly support armed forces personnel by enhancing secure communication through improved connectivity.
The network currently operates across more than 92,000 sites, connecting about 22 million Indians in both urban and rural areas, fueling digital inclusion and economic growth. Under the saturation drive, around 29,000 villages have been connected through the Digital Bharat Nidhi (DBN)/4G saturation project. “For two million users, this marks their first entry into the digital era. The network is managing nearly four petabytes of data traffic every day with efficiency and security,” the Ministry noted.
Solar Powered Towers
The towers, powered by solar energy, form India’s largest cluster of green telecom sites, according to reports dated September 27, 2025.
Technology Partners
The fully indigenous 4G technology stack, featuring a Radio Access Network (RAN) developed by Tejas Networks, a core network by C-DOT, and integration by TCS, has been deployed by BSNL under the vision of Aatmanirbhar Bharat.
Indigenous 4G Stack
The ministry highlighted that the entire 4G architecture was indigenously built in just 22 months, a pace significantly faster than comparable nations. “Localised manufacturing and deployment are creating employment, strengthening supplier ecosystems, and nurturing a skilled domestic workforce capable of designing, testing, and maintaining advanced telecom systems. This adds both human capital and supply-chain autonomy to India’s telecom sector,” it said.
The fully indigenous 4G stack is not only meeting India’s internal requirements but is also designed with export potential, with several countries having already expressed interest.
5G Use Cases
The Ministry also outlined potential 5G use cases:
Agriculture: 5G will empower precision farming and smart agriculture with real-time data from IoT sensors, drones, and AI for enhanced productivity and resource management.
Healthcare: 5G enables telemedicine, remote diagnostics, and real-time health monitoring, improving healthcare access especially in rural areas.
Education: Enhanced virtual classrooms and immersive augmented/virtual reality (AR/VR) experiences will improve remote learning opportunities.
Manufacturing and Industry 4.0: 5G supports automation, robotics, and smart factories with ultra-reliable, low-latency communication for increased efficiency and safety.
Smart Cities: It enables intelligent traffic management, energy-efficient infrastructure, public safety, and environmental monitoring through connected devices.
Automotive and Transport: 5G facilitates connected and autonomous vehicles, real-time traffic updates, and safer road transport systems.
Entertainment and Media: Enhanced high-definition streaming, immersive gaming, and interactive media experiences will be possible.
