The Telecom Regulatory Authority of India (TRAI) released its Independent Drive Test (IDT) findings for
the Assam LSA, covering extensive city routes of Barpeta and Bongaigaon Districts in the month of
October 2025. The drive tests, conducted under the supervision of the TRAI Regional Office, Kolkata,
were designed to capture real-world mobile network performance across diverse usage environments-
