State-owned Bharat Sanchar Nigam Ltd (BSNL) is experiencing weak transmission signals from thousands of its new 4G towers, leading to call drops and slower data speeds. This issue surfaces as BSNL attempts a turnaround with government support. Vendors Tata Consultancy Services (TCS) and Tejas Networks have been asked to investigate and fix the problem, though they claim most issues are resolved and KPIs are unaffected. Telecom Regulatory Authority of India (TRAI) tests have shown BSNL's network performing worse than private competitors in speed and call drop rates.
