BSNL, India's state-owned operator, is moving closer to launching 5G services as its long-delayed 4G network finally gains commercial traction.

The operator's 4G deployment, which has trailed far behind private rivals Jio and Airtel for years, is now expanding to more sites and circles, according to a report by TelecomTalk. That progress matters because BSNL's 5G ambitions rest almost entirely on the 4G core it is building today: the next-generation network will ride on the same infrastructure rather than on a separate greenfield build.

For a carrier that spent years stuck in procurement disputes, technology trials and equipment-sourcing questions, a functioning 4G layer is the precondition for everything that follows. The report positions the 4G expansion as the concrete step that brings 5G within realistic reach for the operator.

Why does 4G momentum decide BSNL's 5G timing?

BSNL's path to 5G has been sequential by design rather than by choice. The operator missed the 4G wave that transformed the Indian market in 2016 and after, leaving it competing with a 2G/3G-heavy footprint while Jio and Airtel scaled nationwide 4G and then raced into 5G.

A non-standalone-style progression — upgrading an installed 4G base before adding 5G radio on top — is the standard route for carriers with constrained budgets. For BSNL, whose financial position has long limited capital spending, there is little appetite for a parallel 5G build while 4G coverage is still incomplete.

The current rollout therefore does double duty. Each 4G site strengthens the subscriber proposition today and becomes a potential anchor for 5G tomorrow. The TelecomTalk report frames the operator's improving 4G footprint as evidence that the 5G milestone is now approaching rather than receding.

What has held BSNL back until now?

The operator's modernization effort has been shaped by two persistent constraints.

• Procurement delays. Tenders for 4G equipment ran into repeated legal and procedural challenges, stretching the upgrade cycle across several years.
• Indigenous technology mandates. Government policy pushed BSNL toward domestically developed telecom gear, a requirement private operators do not face to the same degree. The state-backed strategy supports India's local manufacturing goals but has added complexity to BSNL's vendor selection and rollout speed.

Those pressures help explain why BSNL's 4G story has unfolded so differently from its private competitors, and why each visible gain in coverage carries weight beyond the raw site count.

Can a state operator still compete in India's 5G market?

The commercial context is unforgiving. Jio and Airtel have already built nationwide 5G footprints and are pushing subscribers onto next-generation plans, while Vodafone Idea works through its own restructuring. BSNL enters this market late, with a 4G network still in expansion and 5G yet to begin.

Yet BSNL retains assets its rivals cannot replicate: a government owner with an explicit interest in its survival, deep rural coverage obligations and a subscriber base that stays partly on price-sensitive plans the private sector has abandoned through repeated tariff hikes.

The operator's 5G case, then, is not about matching Jio's rollout speed. It is about converting a delayed but functional 4G foundation into a credible next-generation offer before the technology gap widens further.

The report suggests the gap is now closing rather than growing. If the 4G expansion continues at its current pace, BSNL's first 5G deployments would follow on infrastructure it already owns and operates — a modest but financially rational route into the market.

How quickly that translates into commercial 5G services will depend on the pace of the remaining 4G rollout and on continued government backing for the operator's modernization program.
