TRAI Assesses Mobile Network Quality on Gandhidham to Santhalpur National Highway (NH-27) in Gujarat LSA

Ministry of Communications TRAI Assesses Mobile Network Quality on Gandhidham to Santhalpur National Highway (NH-27) in Gujarat LSA

Posted On: 22 SEP 2026 1:29PM by PIB Delhi The Telecom Regulatory Authority of India (TRAI) has released findings of Independent Drive Test (IDT) conducted on Gandhidham to Santhalpur National Highway (NH-27) in Gujarat LSA, during the month of July 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 test from Gandhidham to Santhalpur National Highway(NH-27) on 1st July 2026, covering 149.1 KMs (Gujarat LSA). This test was 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).

b. Voice Services: Call Setup Success Rate (CSSR), Drop Call Rate (DCR), Call Setup Time, Call Silence Rate, Speech Quality (MOS). c. Call Silence Instance: Number of call silence instance occurred during the calls.

d. Data Servies: Download/ Upload Throughput, Latency, Jitter, Packet Drop Rate.

The overall mobile network performance on Gandhidham to Santhalpur National Highway (NH-27) in

Gujarat LSA for the key parameters has been summarised below: a. Coverage Gap - The signal strength observed during voice testing on the drive test route in auto-selection mode (5G/4G/3G/2G), measured as the number of samples having poor signal strength out of the total samples collected, was 1253/17251 for Airtel, 2246/14269 for BSNL, 225/17324 for RJIL and 1239/17241 for VIL.

provided in the map Annexed. b. Dropped Calls - Dropped calls, measured as the number of dropped calls out of the number of successfully established calls, were 0/85 for Airtel, 11/76 for BSNL, 0/86 for RJIL and 1/86 for VIL. Details of the dropped call locations have been provided in the map Annexed.

c. Call Silence Instance - Call silence instances, measured as the total number of silence instances observed for > 3 seconds out of the total calls established, were 7/86 for Airtel, 9/67 for BSNL, 1/82 for RJIL. 5/83 For VIL. 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 146.35 Mbps for Airtel (5G/4G), 20.23 Mbps for BSNL (4G/3G/2G), 223.70 Mbps for RJIL (5G/4G) and 23.76 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 21.00 Mbps for Airtel (5G/4G), 6.35 Mbps for BSNL (4G/3G/2G), 22.18 Mbps for RJIL (5G/4G) and

13.00 Mbps for VIL (5G/4G/2G). Detail of upload throughput has been provided in the map Annexed.
