Executive Summary
The Telecom Regulatory Authority of India (TRAI) released findings from an Independent Drive Test (IDT) conducted between June 16 and June 20, 2026, across the Godda Lok Sabha Constituency in Jharkhand. The report evaluates the real-time quality of service (QoS) for voice and data provided by Telecom Service Providers (TSPs) to inform consumers and encourage infrastructure improvements. Key findings highlight significant disparities in coverage, call reliability, and data throughput among the assessed providers.
Key Points / Main Content
Testing Methodology and Scope
The IDT covered 486.7 KMs of city drives, 17 hotspot locations, and 2.1 KMs of walk tests in crowded pedestrian environments like Jasidih and Madhupur Junction railway stations.
Testing utilized live SIM cards across 2G, 3G, 4G, and 5G networks, monitored via advanced software systems to capture real-world user experiences.
Specific hotspots included critical locations such as AIIMS Deoghar, District Courts, and various colleges and hospitals across Deoghar, Godda, and Dumka districts.
Voice Service Performance
Coverage Gaps: RJIL (1,643) and Airtel (2,497) recorded the lowest number of poor signal samples, whereas BSNL (22,508) and VIL (20,905) showed significantly higher coverage gaps.
Dropped Calls: Airtel recorded 0 dropped calls out of 498 samples. In contrast, VIL and BSNL recorded the highest number of drops at 25 and 23 respectively.
Call Silence: VIL (51) and BSNL (47) instances of call silence (>3 seconds) were higher than those of Airtel (16) and RJIL (4).
Data Throughput Results
Download Speeds: RJIL delivered the highest average download speed at 182.22 Mbps, followed by Airtel at 90.75 Mbps. BSNL recorded the lowest average at 6.84 Mbps.
Upload Speeds: Airtel and VIL shared the highest average upload speeds at 8.0 Mbps, while BSNL recorded the lowest at 3.0 Mbps.
Impact Analysis
Telecom Service Providers (Airtel, BSNL, RJIL, VIL)Impact
The report publicly identifies specific geographical areas and technical parameters where each TSP is underperforming, particularly regarding coverage gaps and call drop rates.
Action Required
TSPs are encouraged to analyze the annexed maps and data to identify network weak spots and improve infrastructure to meet Quality of Service (QoS) standards.
General Telecom ConsumersImpact
Consumers in the Godda Lok Sabha Constituency gain access to independent, real-time performance data for voice and data services.
Action Required
Consumers can use the report findings to make informed decisions regarding which service provider offers the most reliable coverage and highest speeds in their specific locality.
Telecom Regulatory Authority of India (TRAI)Impact
The drive tests fulfill the regulator's role in monitoring and verifying the actual service quality provided to the public versus theoretical standards.
Action Required
TRAI, through its Regional Office in Kolkata, will continue to monitor TSP performance and publish these findings to maintain transparency and pressure providers for service upgrades.

adjoining areas in the State of Jharkhand under
Bihar LSA
प्रव तथ: 28 JUL 2026 3:15PM by PIB Delhi
The Telecom Regulatory Authority of India (TRAI) has released findings of Independent Drive Test (IDT)
conducted across Godda Lok Sabha Constituency comprising parts of Deoghar, Godda and Dumka
Districts and adjoining areas in the State of Jharkhand under Bihar LSA, during the month of June 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 – 486.7 KMs, Hotspot
locations - 17, Walk Test – 2.1 KMs in Jharkhand State during 16th June 2026 to 20th June 2026 in Bihar
LSA. These tests were conducted under the supervision of the TRAI Regional Office Kolkata. 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 City drive,
Inter-operator calling, Hotspots and Walk tests, 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).
