TRAI released the findings of the Independent Drive Test (IDT) conducted across metro routes under the Delhi Metro Rail Corporation, Noida Metro Rail Corporation and National Capital Region Transport Corporation in the Delhi LSA during April 2026 for the information of general telecom consumers.

The purpose of this drive test is to assess and verify the real-time quality of mobile network services (both voice and data) provided by Telecom Service Providers (TSPs).

During the IDT, TRAI captures TSP performance for key Quality of Service (QoS) parameters like Coverage, Call Drop Rate (CDR), Call Setup Success Rate (CSSR), data Download (DL) and Upload (UL) throughput etc, which are then published to inform consumers and encourage TSPs to improve their services.

These IDTs have been designed to capture on ground mobile network performance of all TSPs across diverse usage environments like cities, hotspots, public transport hubs, etc.

In this type of drive testing, live data and voice sessions are established using SIM cards from all TSPs over 2G, 3G, 4G, and 5G networks.

Multiple advanced test handsets are used, and the sessions are monitored and analysed in real-time using advanced Software Systems.

TRAI, through its appointed agency, conducted drive tests across 490 km of metro routes in the Delhi LSA during April 1st to 4th, 2026, and on 14th April 2026.

These tests were conducted under the supervision of the TRAI Regional Office Delhi.

The observations presented in drive test reports represent the performance of the TSPs on the tested area/route on the day/time the drive test was conducted.
