TRAI evaluates mobile network quality on Delhi metro routes

The Telecom Regulatory Authority of India (TRAI) assessed mobile network quality across metro routes in Delhi, Noida, and NCR during April 2026. The drive tests evaluated voice and data performance of telecom providers on 490 km of metro routes, including key parameters like signal coverage, call drop rates, and data speeds.

TRAI conducted these tests to provide real-time insights into the quality of services offered by telecom providers such as Airtel, MTNL, RJIL, and VIL. The tests covered metro routes like the Blue Line, Yellow Line, Magenta Line, and the Namo Bharat RRTS corridor. Advanced software and test handsets were used to measure performance across 2G, 3G, 4G, and 5G networks.

Key findings revealed that RJIL had the highest average download speed at 141.28 Mbps (5G), while MTNL recorded the lowest at 4.30 Mbps (4G). Call drop rates varied, with MTNL experiencing the highest at 51 dropped calls out of 346 established calls. Signal coverage gaps were also noted, with MTNL showing the most significant coverage issues.

TRAI has shared these findings with telecom providers to encourage service improvements. Detailed reports are available on the TRAI website, providing consumers with transparency and actionable insights into network performance.

These assessments aim to ensure better connectivity for commuters and hold service providers accountable for maintaining quality standards in public transport hubs like metro routes.
