TRAI Releases Mobile Network Quality Assessment Findings for Vijayanagara District

The Telecom Regulatory Authority of India (TRAI) has published the findings of an Independent Drive Test (IDT) conducted in August 2026 across the Vijayanagara District within the Karnataka Licensed Service Area (LSA). The assessment aimed to evaluate real-time voice and data quality parameters for major Telecom Service Providers (TSPs).

Scope of the Drive Test

Conducted under the supervision of TRAI's Bengaluru Regional Office from August 11 to August 14, 2026, the testing covered multiple environments:

• City Drive: 439.8 kilometers across towns including Hampi, Hosapete, Harapanahalli, and Kotturu.
• Highway Drive: 74 kilometers along NH-50 from Hosapete to Banavikallu.
• Hotspots: 13 key public locations, such as the Hampi temple complexes, railway stations, and local administrative offices.
• Walk Test: 7.6 kilometers covering specific pedestrian zones.

Assessed Parameters and Findings

The IDT evaluated coverage gaps, voice performance (including dropped calls and call silence instances), and data throughput metrics across operators including Airtel, BSNL, RJIL, and VIL.

• Voice Quality & Dropped Calls: Voice testing measured successful call setups against dropped calls and silence instances exceeding three seconds. For instance, in district-wide checks, BSNL recorded 37 dropped calls out of 425 established calls, while Airtel recorded 1 out of 471, RJIL recorded 2 out of 478, and VIL recorded 8 out of 467.
• Data Throughput: Average download and upload speeds varied by operator technology mix (5G, 4G, 3G, 2G). Average download speeds reached 151.30 Mbps for RJIL and 87.50 Mbps for Airtel, compared to 22.09 Mbps for VIL and 10.47 Mbps for BSNL.

Next Steps and Verification

The findings have been shared with the respective TSPs to prompt necessary service improvements.
