The Telecom Regulatory Authority of India (TRAI) released its Independent Drive Test (IDT) findings for the Chitradurga, Karnataka Licensed Service Area (LSA), covering extensive city/highway routes during the month of December 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.

From 02nd December 2025 to 05th December 2025, TRAI teams conducted detailed tests across 401.2 km of Chitradurga City and the surrounding area, including 393.2 km of city drive, 13 hot spots, and an 8.0 km walk test. 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.

Key Parameters Assessed:

 

a) Voice Services: Call Setup Success Rate (CSSR), Drop Call Rate (DCR), Call Setup Time, Call Silence Rate, Speech Quality (MOS), and coverage.

 

b) Data Services: Download/Upload Throughput, Latency, Jitter, Packet Drop Rate, and Video Streaming Delay.

 

Call Setup Success Rate—Airtel, BSNL, RJIL, and VIL have 97.90%, 79.86%, 96.77%, and 76.10% call setup success rates, respectively, in auto-selection mode (5G/4G/3G/2G).

 

Drop Call Rate—Airtel, BSNL, RJIL, and VIL have drop call rates of 0.39%, 3.63%, 0.98%, and 2.08%, respectively, in auto-selection mode (5G/4G/3G/2G).

 

Summary of Performance against Key QoS Parameters

CSSR: Call Setup Success Rate (i.e., in %), CST: Call Setup Time (in seconds), DCR: Drop Call Rate (in %), & MOS: Mean Opinion Score representing typical voice quality.
