TRAI Assesses Mobile Network Quality Across Kathgodam to Dehradun Railway route passing through Haldwani, Lal Kuan, Rudrapur City, Rampur, Moradabad, Najibabad Junction, Haridwar etc.

Key developments

The Telecom Regulatory Authority of India (TRAI) has released findings of Independent Drive Test (IDT) conducted through its appointed agency across Kathgodam to Dehradun Railway under UPW LSA, during the month of August 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). The performance of TSPs for key Quality of Service (QoS) parameters, captured during IDT are 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. `

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

The drive tests conducted across City drive – 335.8 KMs Kathgodam to Dehradun Railway from 13th August 2026 in UP West LSA.
