Mobile Network Quality Across West Bengal: Jio Leads 5G Speeds, BSNL Lags in Reliability

Why It Matters

The findings highlight a widening gap between private operators and the state‑run BSNL, signaling shifting market dynamics and prompting regulators and investors to reassess network investment priorities in India’s fast‑growing telecom sector.

Key Takeaways

• Jio tops 5G download speed at 212.68 Mbps in West Bengal
• Vodafone Idea leads call success rate at 99.91 % and low drop rate
• BSNL lags with 83.79 % call success and high drop rate 5.85 %
• Jio achieves fastest call setup time of 0.62 seconds
• BSNL records poor signal samples over 30 % across all routes

Pulse Analysis

TRAI’s extensive drive‑test in West Bengal, spanning 436 km of city streets, 364 km of highways and 107 km of railway tracks, offers a granular view of real‑world user experience across 2G‑5G networks. By combining vehicle‑mounted measurements with walk‑tests at 28 hotspot locations, the regulator captured variations in voice quality, data throughput and latency that reflect the challenges of delivering consistent service in densely populated and high‑mobility corridors.

The data paints a clear picture of private operators pulling ahead. Jio’s 5G download average of 212.68 Mbps dwarfs BSNL’s 12.50 Mbps, while its 0.62‑second call setup time sets a new benchmark for responsiveness. Vodafone Idea’s near‑perfect call‑setup success (99.91 %) and Airtel’s strong upload speeds further underscore the competitive edge of the private sector. In contrast, BSNL’s 83.79 % call success, 5.85 % drop‑call rate and over‑30 % poor‑signal samples reveal systemic reliability issues that could erode its remaining subscriber base.

For investors and policymakers, the results signal where capital should flow. Enhancing network densification on highways and rail corridors—areas where performance variability remains high—will be crucial for sustaining growth in mobile data consumption. Regulators may need to tighten service‑quality mandates for legacy operators while encouraging spectrum sharing or infrastructure sharing to accelerate 5G rollout. As Indian consumers increasingly demand seamless high‑speed connectivity, operators that can consistently deliver low latency and robust signal strength are poised to capture market share and drive the next wave of digital services.
