The Telecom Regulatory Authority of India (TRAI) has released the findings of Independent Drive Test (IDT) conducted across Hyderabad City under AP 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 across city drive - 157.9 Kms, Hotspot locations - 12, Walk Test – 3.1 Kms in Hyderabad city during 14^th May 2026 to 16^th May 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.

Details of the call silence instance locations have been provided in the map Annexed.

d)    Data Download and Upload Throughput:

i)  Data Download performance (Overall): Average download speed was observed as 66.32 Mbps for Airtel (5G/4G), 5.55 Mbps for BSNL (3G), 222.12 Mbps for RJIL (5G/4G) and 59.61 Mbps for VIL (5G/4G/2G). Detail of Download throughput has been provided in the map Annexed.

ii) Data Upload performance (Overall): Average upload speed was observed as 24.54 Mbps for Airtel (5G/4G), 2.54 Mbps for BSNL (3G), 19.43 Mbps for RJIL (5G/4G) and 13.17 Mbps for VIL (5G/4G/2G). Detail of Upload throughput has been provided in the map Annexed.
