India Enters the Elite Club of Nations with Indigenous 4G Technology

On September 27, 2025, a significant milestone was achieved in India’s telecommunications landscape as Prime Minister Narendra Modi inaugurated Bharat Sanchar Nigam Limited’s (BSNL) 4G services. This event sparked a wave of discussions and reactions online, with some critics mocking the timing of the launch, given the global shift towards 5G technology. However, the reality is that India is now part of an exclusive group of nations that boast an indigenous 4G technology stack, a feat that was previously the domain of advanced economies like China, Finland, Sweden, and South Korea.

The Importance of Indigenous Technology

One of the key highlights of this development is the indigenous nature of the technology utilized in BSNL’s 4G services. The core network is powered by the Centre for Development of Telematics (C-DOT), while the Radio Access Network (RAN) is provided by Tejas Networks. The integration of these components has been executed by Tata Consultancy Services (TCS), showcasing India’s growing capabilities in the telecommunications sector.

Having an indigenous 4G stack is a landmark achievement for India, as it not only reduces dependency on foreign technology but also strengthens the country’s position in the global tech ecosystem. This advancement is critical for national security, economic growth, and technological self-reliance.

The Reaction to the Inauguration

The inauguration event drew mixed reactions, particularly on social media. While some users expressed skepticism about the relevance of launching 4G in an era dominated by 5G, others praised the achievement as a significant leap forward for India’s technological landscape. Critics often overlook the fact that 4G technology still plays a vital role in telecommunications, especially in rural and underdeveloped areas where 5G infrastructure is yet to be established.

4G vs. 5G: Understanding the Transition

It’s essential to recognize that 4G technology is not obsolete; rather, it serves as a crucial stepping stone towards the broader adoption of 5G. While 5G promises faster speeds and more reliable connections, 4G remains highly relevant and continues to support a vast array of applications in everyday life. Many users worldwide still rely on 4G networks, particularly in areas where 5G has not yet been deployed.

Moreover, the introduction of an indigenous 4G stack benefits India in several ways:

1. Economic Growth: A robust telecommunications infrastructure is vital for economic development. By investing in indigenous technology, India can create job opportunities and foster innovation.
2. Digital Inclusion: With BSNL’s 4G services reaching a broader audience, more people can access the internet, leading to increased digital literacy and inclusion.
3. National Security: Utilizing homegrown technology minimizes the risks associated with foreign dependency, which is crucial for national security.
   

   Technological Advancements and Future Prospects
   

   The collaboration between C-DOT, Tejas Networks, and TCS is a testament to India’s advancing capabilities in technology. This partnership is expected to pave the way for future innovations in telecommunications and other sectors.

   As the world progresses towards 5G and beyond, having a solid foundation in 4G technology will prove advantageous for India. The country can leverage its indigenous stack to develop 5G technologies in the future, ensuring that it remains competitive on the global stage.

   Conclusion
   

   The launch of BSNL’s 4G services marks a significant achievement for India, positioning the country as a member of the elite club of nations with indigenous telecommunications technology. Despite the criticism regarding the timing of the launch in the context of 5G, it’s crucial to recognize the importance of 4G in today’s technological landscape.

   India’s advancements in telecommunications not only enhance national security but also contribute to economic growth and digital inclusion. With strong collaborations between key players in the tech industry, the future looks bright for India’s telecommunications sector, and the country is well on its way to becoming a global leader in technology innovation.

   In summary, while the conversation may focus on 5G, the launch of BSNL’s 4G services is a significant step forward for India, showcasing the nation’s commitment to technological self-reliance and innovation. As India continues to develop its telecommunications infrastructure, it will be essential to monitor how these advancements impact the economy, national security, and society as a whole.
