State-run BSNL is now processing 6 petabytes of daily data traffic on its indigenous 4G network, supported by 1.75 lakh base stations. While the network expansion signals a strategic shift in technology and coverage, the company continues to battle intense competition from private operators and faces persistent financial losses.
Bharat Sanchar Nigam Limited (BSNL) has achieved a new operational milestone, with its indigenous 4G network now handling 6 petabytes of data traffic every day. This capacity is supported by an infrastructure rollout that includes 1.75 lakh base stations deployed across 1 lakh sites nationwide. This development marks a significant phase in the state-run telco's efforts to modernize its network and compete with private sector rivals like Reliance Jio, Bharti Airtel, and Vodafone Idea.
The network is powered by an indigenous technology stack developed by a consortium including the Centre for Development of Telematics (C-DoT), Tata Consultancy Services (TCS), and Tejas Networks. By moving away from foreign vendors for its core equipment, BSNL aims to build a more resilient supply chain and reduce long-term dependency. The infrastructure currently supports a substantial user base and is being optimized for high-definition voice services through the implementation of IP Multimedia Subsystem technology.
While the expansion of the 4G network is a positive operational step, BSNL continues to face significant financial hurdles. In the first quarter of the 2026-27 financial year, the company reported a consolidated net loss of Rs 1,280 crore. Although this reflects a slight improvement from the previous quarter's loss of Rs 1,419 crore, it highlights the ongoing difficulty in returning to profitability. The company has seen a positive trend in its Average Revenue Per User, which has risen to approximately Rs 103, yet this remains lower than the levels seen among major private telecom operators.
The primary challenge for BSNL remains the intense competition in the Indian telecom sector. Private players have long dominated the 4G and 5G landscape, and BSNL’s ability to retain and grow its subscriber base will depend on its service quality and coverage consistency. High operating expenses, including network maintenance and employee costs, continue to weigh on the company's balance sheet. Furthermore, the company is managing the execution risk associated with its large-scale capital expenditure plans as it seeks to upgrade its capabilities.
Looking ahead, BSNL has commenced field trials for 5G Radio Access Network technology in Ambala, utilizing the 3600-3700MHz spectrum range. The transition to 5G is seen as a crucial step to bridge the service gap with commercial offerings from private rivals. Investors and industry observers will be tracking the company's ability to maintain its 4G network performance, manage project timelines for the 5G rollout, and gradually reduce its financial losses in upcoming quarters.
