**Executive Summary**
The Telecom Regulatory Authority of India (TRAI) released the results of Independent Drive Tests (IDT) conducted in June 2026 to assess mobile network quality in Barmer, Balotra, Pachpadra, and surrounding areas in Rajasthan. The tests evaluated 2G, 3G, 4G, and 5G performance across key parameters including coverage, call drops, and data throughput to inform consumers and encourage service improvements. Findings have been shared with Telecom Service Providers (TSPs) for necessary remedial actions to address identified service gaps.
**Key Points / Main Content**
**Test Methodology and Scope**
* The IDT covered 350.3 KMs of city drives and 07 hotspot locations between June 1st and June 4th, 2026.
* Testing utilized SIM cards from all TSPs across 2G, 3G, 4G, and 5G networks using advanced software and multiple test handsets.
* The assessment included Coverage Gaps, Call Setup Success Rate (CSSR), Drop Call Rate (DCR), and data Download/Upload throughput.
**Voice Service Performance**
* **Coverage Gaps:** RJIL recorded the fewest poor signal samples (355/28,540), followed by Airtel (874/28,421). BSNL (6,332/21,622) and VIL (4,378/27,385) showed significantly higher coverage gaps.
* **Dropped Calls:** Airtel recorded zero dropped calls (0/255). BSNL had the highest number of drops (8/183), followed by VIL (7/251) and RJIL (2/260).
* **Call Silence:** Airtel achieved zero call silence instances. BSNL (24/143) and VIL (30/236) recorded the highest rates of call silence lasting over three seconds.
**Data Throughput Performance**
* **Download Speeds:** RJIL delivered the highest average download speed at 228.12 Mbps. Airtel followed at 145.06 Mbps, while VIL (22.40 Mbps) and BSNL (8.11 Mbps) recorded substantially lower speeds.
* **Upload Speeds:** Airtel achieved the highest average upload speed at 24.57 Mbps, followed closely by RJIL at 22.28 Mbps. BSNL recorded the lowest upload speed at 3.60 Mbps.
**Impact Analysis**
**Stakeholder: Telecom Service Providers (Airtel, BSNL, RJIL, VIL)**
**Impact**
Providers are publicly benchmarked on real-time performance, highlighting specific technical failures in coverage, voice stability, and data speeds.
**Action Required**
Review the detailed findings shared by TRAI and initiate necessary infrastructure or configuration changes to address identified gaps and improve Quality of Service (QoS).
**Stakeholder: General Telecom Consumers**
**Impact**
Consumers receive transparent, verified data regarding the actual performance of various networks in the Barmer, Balotra, and Pachpadra regions.
**Action Required**
Utilize the published QoS parameters and the drive test route maps to make informed decisions when selecting a service provider.
**Stakeholder: TRAI (Regulatory Body)**
**Impact**
The regulatory body identifies specific regions and providers failing to meet quality standards, facilitating data-driven oversight.
**Action Required**
Continue monitoring TSP performance, publish detailed reports on the official website, and supervise the "necessary action" taken by providers to ensure network improvements.

TRAI Assesses Mobile Network Quality across
Barmer, Balotra, Pachpadra city and adjoining
areas (in Rajasthan LSA)
प्रव तथ: 09 JUL 2026 1:28PM by PIB Delhi
The Telecom Regulatory Authority of India (TRAI) has released findings of Independent Drive Test (IDT)
conducted across Barmer, Balotra, Pachpadra city and adjoining areas (in Rajasthan 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 – 350.3 KMs, Hotspot
locations - 07 of Barmer, Balotra, Pachpadra city and adjoining areas (in Rajasthan LSA) during 1st
June 2026 to 2nd June & on 4th June 2026 in Rajasthan LSA. These tests were conducted under the
supervision of the TRAI Regional Office Jaipur. The observations presented in the 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).
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.
