TRAI Assesses Network Quality Across Mangaluru City and Surrounding Area
Summary of Performance against key QoS parameters
The Telecom Regulatory Authority of India (TRAI) released its Independent Drive Test (IDT) findings for the Mangaluru, Karnataka Licensed Service Area (LSA), covering extensive City/Highway routes during the month of July 2025. The drive tests, conducted under the supervision of the TRAI Regional Office, Bengaluru, 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 07th July 2025 to 11th July 2025, TRAI teams conducted detailed tests across 313.2 kms of City Test, 3.4 Kms of coastal Test, 10.0 kms of Walk Test and 11 Hotspot locations. Technologies evaluated included 2G, 3G, 4G, and 5G, reflecting the service experience of users across multiple handset capabilities. The findings of IDT have been intimated to all the TSPs concerned for further necessary action.
