TRAI Assesses Mobile Network Quality on
Jodhpur to Ahmedabad Rail Route (Rajasthan &
Gujarat LSA)
प्रव तथ: 29 JUN 2026 1:34PM by PIB Delhi
The Telecom Regulatory Authority of India (TRAI) has released findings of Independent Drive Test (IDT)
conducted on Jodhpur to Ahmedabad Rail Route (Rajasthan & Gujarat LSA), during the month of
May 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.
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 from Jodhpur to Ahmedabad Rail Route on 4th
May 2026, covering 456.9 KMs (Rajasthan & Gujarat LSA). These tests were conducted under the
supervision of the TRAI Regional Office Jaipur. 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 route as per the legends
shown on the map: -Key Parameters Assessed:
a. Coverage Gap: Percentage of samples, for which signal strength observed less than the minimum
prescribed signal strength for respective technology (2G/ 3G/ 4G/ 5G).
