TCS-Led Consortium Driving Indigenous Deployment

BSNL’s ongoing 4G deployment, being executed by a Tata Consultancy Services (TCS)-led consortium, has seen significant progress, with more than 97,000 mobile towers already operational. BSNL is now working on follow-on orders to further expand its network footprint, particularly in underserved and unserved areas.
