TRAI Assesses Mobile Network Quality Across Highway Route- Hindupur to Hyderabad passing through Anantapur, Dhone, Kurnool and Jadcherla etc.
Railway Route- Hyderabad to Hindupur passing through Jadcherla, Kurnool Town, Dhone Junction, Gooty Junction, Anantapur and Dharmavaram Junction etc.
The Telecom Regulatory Authority of India (TRAI) has released findings of Independent Drive Test (IDT) conducted across Rail Hyderabad to Hindupur and Highway Hindupur to Hyderabad under AP LSA, during the month of April 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 across Highway - 473.7 KMs and Railway - 515.8 Kms, Hindupur to Hyderabad - Highway and Hyderabad to Hindupur - Railway from 20th April 2026 to 21st April 2026 in Andhra Pradesh LSA. These tests were conducted under the supervision of the TRAI Regional Office Hyderabad. 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 Highway and Railway as per the legends shown on the map:-
Key Parameters Assessed
The overall mobile network performance in Hyderabad for the key parameters has been summarised below:-
