TRAI Releases Independent Drive Test Findings for Hyderabad and Adoni-Mantralayam

Overview of TRAI Network Quality Assessment

The Telecom Regulatory Authority of India (TRAI) has published the findings of its Independent Drive Tests (IDT) conducted in September 2026. The assessment evaluates the real-time quality of mobile network services, including voice and data, provided by various Telecom Service Providers (TSPs) across Hyderabad and the Adoni-Mantralayam regions within the Andhra Pradesh Licensed Service Area (LSA).

The testing program is designed to monitor key Quality of Service (QoS) parameters, providing transparency for consumers and encouraging service providers to enhance infrastructure performance.

Assessment Methodology

The drive tests capture on-ground network functionality across diverse environments, such as urban centers, transit routes, walk test zones, and static hotspots. Advanced test equipment running across 2G, 3G, 4G, and 5G networks utilizes multi-SIM handsets to log metrics continuously.

Key parameters evaluated during the assessments include:

• Coverage Gaps: Frequency of signal samples falling below required minimum thresholds.
• Voice Metrics: Call Setup Success Rate (CSSR), Drop Call Rate (DCR), speech quality via Mean Opinion Score (MOS), and call silence instances.
• Data Performance: Average download and upload throughput, latency, and packet loss rates.

Summary of Findings

The reported metrics reflect network behavior specifically on the routes and times tested under the supervision of TRAI's Hyderabad Regional Office.

• Hyderabad Area: Assessments covered key localities, transit paths, walk tests at locations like AIG Hospital Gachibowli and the airport, alongside designated hotspots. Average download speeds recorded during the test period reached up to 145.79 Mbps for RJIL and 82.88 Mbps for Airtel, while BSNL and VIL registered respective averages.
• Adoni-Mantralayam Region: Testing spanned extensive highway routes, local corridors, and stationary locations such as the Raghavendra Swamy Matha and regional colleges, capturing localized coverage variations and data throughput capabilities.

Practical Implications and Verification

The findings have been shared with the respective TSPs to facilitate remedial measures where performance gaps were identified.
