- Call Setup Time (CST): RJIL fastest at 0.75 sec; BSNL slowest at 2.45 sec
- Drop Call Rate (DCR): VIL 0%, RJIL 0.49%, AIRTEL 2.7%, BSNL 3.32%
- Call Silence Rate: VIL 2.25%, AIRTEL 3.47%, BSNL 1.57%, RJIL 0.77%
- Mean Opinion Score (MOS): VIL highest at 4.40, AIRTEL 3.90, RJIL 3.81, BSNL 2.84
Data Service Performance
Data network quality in auto-selection mode revealed significant variations:
- Average Download Speed: RJIL 172.58 Mbps, AIRTEL 103.06 Mbps, VIL 27.41 Mbps, BSNL 4.66 Mbps
- Average Upload Speed: AIRTEL 19.16 Mbps, RJIL 14.20 Mbps, VIL 11.16 Mbps, BSNL 4.09 Mbps
- Latency (50th percentile): AIRTEL 25.65 ms, BSNL 27.68 ms, RJIL 28.45 ms, VIL 32.20 ms
Methodology and Scope
The IDT involved live voice and data sessions using SIM cards from all telecom service providers across 2G, 3G, 4G, and 5G networks. Tests were conducted in commercial zones, public transport hubs, and hotspot areas using multiple advanced handsets. All sessions were monitored and analyzed in real time with sophisticated software systems to ensure accurate performance measurements.
