Test Scope and Methodology
The drive tests, conducted under the supervision of the TRAI Regional Office, Delhi, were designed to capture real-world mobile network performance across diverse usage environments – Urban Zones, Institutional Hotspots, Public Transport Hubs, and High-Speed Corridors.
Between 08th September 2025 to 11th September 2025, TRAI teams conducted detailed tests across 280.8 km of City Drive Test, 13 Hotspot locations, 3.4 km of walk test, and Inter Operator Calling at 01 location. Technologies evaluated included 2G, 3G, 4G, and 5G, reflecting the service experience of users across multiple handset capabilities. The findings of IDT have already been intimated to all the TSPs concerned.
