The findings of this IDT report have been shared with respective TSPs for taking further necessary action at their end. Detailed reports of IDT are made available on the TRAI website at www.trai.gov.in. For any clarification or additional information, an email can be sent to adv.ca@trai.gov or Regional Office of TRAI at Delhi RO can be contacted on telephone no. +91-11-20907772.
The Telecom Regulatory Authority of India (TRAI) has released findings of Independent Drive Test (IDT) conducted across North Delhi and nearby areas Route under Delhi LSA, during the month of Apr 2026, for information of general telecom consumers. The purpose of this drive test is to assess and verify real time quality of mobile network services (both voice & data) provided by Telecom Service Providers (TSPs). During the IDT, TRAI captures performance of TSPs 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.
Annexure-I
Note: Call silence instances are shown in red colour, and which can be clicked to know the exact location (latitude and longitude) on the map.
Note: Signal strength has been considered poor if it falls below -110 dBm for 5G & 4G, -90 dBm for 3G, and -85 dBm for 2G.
Note: Call silence instances are shown in red colour and which can be clicked to know the exact location (latitude and longitude) on the map.
These IDTs have been designed to capture on ground mobile network performance of all TSPs across diverse usages environment 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 City drive - 374.2 Kms, Hotspot locations - 13, Walk Test - 7.0 Kms and Airport Route - 57.8 Kms from 13th Apr 2026 to 17th Apr 2026 in Delhi LSA. 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 area/ route under test on the day/ time of conducting the drive test.
Drive Test Route Map: The following map provides overview of drive test routes indicating City drive, Inter-operator calling, Hotspots and Walk tests, as per the legends shown on the map: -
Note: Signal strength has been considered poor if it falls below -110 dBm for 5G & 4G, -90 dBm for 3G, and -85 dBm for 2G.
