CMD confirms that Bharat Sanchar Nigam Limited will add 20,000 new sites, strengthen rural connectivity, and use AI-driven optimization to improve service quality across India.
State-owned telecom company Bharat Sanchar Nigam Limited (BSNL) has confirmed that it will continue expanding its 4G network across India during the financial year 2026-27. The announcement highlights the government-backed telecom operator’s focus on strengthening nationwide connectivity and improving service quality for millions of users.
BSNL Chairman and Managing Director A. Robert J Ravi stated that the company is making steady progress with its current 4G rollout and is now preparing for the next phase of expansion. The move is part of BSNL’s long-term strategy to compete more effectively in India’s fast-changing telecom market.

BSNL 4G Rollout Progress So Far
BSNL’s 4G deployment is being executed by a consortium led by Tata Consultancy Services (TCS). According to the company, more than 97,000 mobile towers are already operational under the ongoing rollout.
This large-scale deployment is helping BSNL improve network availability, especially in rural and semi-urban regions where private telecom operators have limited presence. The company believes that a strong 4G base is essential before moving towards future technologies like 5G.

20,000 New 4G Sites Planned
To further enhance coverage, BSNL is in the process of finalising orders for around 20,000 additional 4G sites. These sites will be deployed across different parts of the country to fill network gaps and improve signal strength.
In addition to this, BSNL has also floated a tender for another 10,000 sites under an operating expenditure (OPEX) model. This approach allows the company to expand its network while keeping capital costs under control.
Focus on Rural and Underserved Areas
One of BSNL’s key priorities is expanding connectivity in underserved and unserved regions. Many rural areas still depend heavily on BSNL for basic telecom services, and the new 4G expansion aims to improve internet speed and call quality in these locations.
By strengthening its presence in remote regions, BSNL is also supporting the government’s vision of digital inclusion and affordable internet access for all citizens.

AI-Driven Network Optimization
BSNL is using artificial intelligence (AI) tools to strengthen and manage its 4G network more efficiently. AI-based systems help monitor network performance, predict faults, and improve overall service reliability.
According to the company, this systematic approach will ensure stable and high-quality 4G services across the country before any major transition to next-generation technologies.

Indigenous Technology Remains a Priority
A major highlight of BSNL’s expansion strategy is its strong focus on indigenous telecom technology. The company is working closely with Indian technology partners to reduce dependence on foreign vendors.
The 4G network is being deployed with support from:
- Tata Consultancy Services (TCS)
- Tejas Networks
- Centre for Development of Telematics (C-DoT)
This collaboration aligns with the government’s “Make in India” initiative and promotes domestic innovation in the telecom sector.

Preparing Ground Before 5G Decision
While private telecom companies in India have aggressively rolled out 5G services, BSNL is taking a more cautious approach. The company plans to consolidate its 4G infrastructure first before making any major decision regarding 5G deployment.
CMD Robert Ravi emphasized that reliable nationwide 4G coverage is currently the top priority. Only after achieving this goal will BSNL evaluate different models for future technology upgrades.

Competition from Private Telecom Operators
India’s private telecom players have moved quickly in the 5G space. Reliance Jio and Bharti Airtel together have installed more than 5 lakh 5G base transceiver stations over the last three years.
On the other hand, Vodafone Idea has taken a selective approach and is rolling out 5G services only in limited locations.
Despite this competition, BSNL believes its strong 4G expansion and affordable plans can help it maintain a loyal customer base.
