The Telecom Regulatory Authority of India (TRAI) released its Independent Drive Test (IDT) findings for the Odisha Licensed Service Area (LSA), covering extensive city of Brahmapur City in the month of December 2025. The drive tests conducted under the supervision of the TRAI Regional Office, Hyderabad, were designed to capture real-world mobile network performance across diverse usage environments- Urban Zones, Institutional Hotspots, rural residential areas etc. 

Between 16^th December 2025 to 18^th December 2025, TRAI teams conducted detailed tests for 360 Kms Brahmapur City drive test, 4.1 Km Walk test and 8 Hotspot locations. Technologies evaluated included 2G, 3G, 4G, and 5G, reflecting the service experience of users across multiple handset capabilities. The findings of the IDT have been intimated to all the TSPs concerned.
