en.Wedoany.com Reported - India's state-owned telecom operator BSNL's 4G network deployment is becoming one of the country's most significant telecom infrastructure projects. Unlike Bharti Airtel and Reliance Jio—which launched 5G after building extensive 4G networks—BSNL is currently focused on constructing a large-scale indigenous 4G network, a project expected to lay the groundwork for its future 5G service rollout.

At the core of BSNL's network expansion is India's indigenous telecom technology stack, developed collaboratively by the Centre for Development of Telematics (C-DOT), Tata Consultancy Services (TCS), and Tejas Networks. The government emphasizes that the equipment is technologically upgradable to 5G, meaning BSNL can transition to next-generation services without rebuilding infrastructure. BSNL is steadily expanding its nationwide 4G coverage, with deployment involving nearly 100,000 sites, thousands of which are already operational.

This scale of deployment makes it one of India's largest indigenous telecom projects. Beyond expanding connectivity, the deployment serves as a practical demonstration of India's domestic telecom technology ecosystem. Industry observers often focus on when BSNL will launch commercial 5G services, but the more critical question is whether the operator can successfully complete its 4G expansion plan and establish a solid network foundation. A successful 4G deployment can bring multiple advantages, including improved coverage, increased network capacity, and helping BSNL consolidate its position in regions where it still holds significant market share. More importantly, it will create a larger infrastructure base to support future 5G services.

The cloud-native architecture used in BSNL's indigenous network is also expected to support smoother technological evolution. Unlike traditional network deployments requiring major hardware changes, cloud-native design enables more flexible software-driven upgrades. Telecom Minister Jyotiraditya Scindia previously stated that BSNL's indigenous 4G network will be upgraded to 5G as deployment progresses.

Despite long-term opportunities, challenges remain. BSNL faces intense market competition, with private operators having established significant 5G footprints. The company not only needs to expand its network but also improve customer experience to attract users in a market where data consumption and digital services continue to grow rapidly. Network quality, customer acquisition, and commercial execution remain key factors determining whether BSNL can effectively leverage its infrastructure investments.
