**Executive Summary**
The Telecom Regulatory Authority of India (TRAI) released findings on July 14, 2026, from an Independent Drive Test (IDT) conducted in June 2026 along the Munabao to Tanot National Highway (NH-70) in Rajasthan. The assessment evaluated the voice and data service quality of all Telecom Service Providers (TSPs) across 311.4 KMs to inform consumers and encourage service improvements. TSPs are required to review the identified performance gaps and take necessary corrective actions.
**Key Points / Main Content**
**Drive Test Methodology**
* The test was conducted on June 3, 2026, under the supervision of the TRAI Regional Office Jaipur, covering routes including Sundra, Myajlar, Gunjangarh, and Longewala.
* Performance was measured across 2G, 3G, 4G, and 5G networks using live sessions and advanced software systems.
* Key parameters included Coverage Gap, Call Setup Success Rate (CSSR), Drop Call Rate (DCR), and data throughput (download/upload speeds).
**Coverage and Voice Performance**
* **Coverage Gaps:** RJIL (Jio) showed the least coverage gaps (881/14,701 samples), while BSNL (8,509/10,174) and VIL (9,227/11,286) recorded significant areas with no coverage.
* **Dropped Calls:** Airtel recorded the highest number of dropped calls at 10 out of 48 successfully established calls.
* **Call Silence:** Instances of silence exceeding three seconds were observed for Airtel, BSNL, and RJIL; VIL's call silence rate could not be captured due to the non-availability of its 4G/5G network.
**Data Throughput Results**
* **Download Speeds:** RJIL recorded the highest average download speed at 55.05 Mbps, followed by Airtel at 42.83 Mbps. BSNL (3.49 Mbps) and VIL (0.35 Mbps) recorded significantly lower speeds.
* **Upload Speeds:** Airtel led in upload performance at 14.03 Mbps, while VIL recorded the lowest average speed at 0.75 Mbps.
**Impact Analysis**
**Telecom Service Providers (Airtel, BSNL, RJIL, VIL)**
**Impact**
The report identifies specific technical failings in their network coverage, call stability, and data delivery along a major national highway.
**Action Required**
TSPs must analyze the shared findings and implement "further necessary action" to address coverage gaps and improve Quality of Service (QoS).
**General Telecom Consumers**
**Impact**
Consumers receive transparent, real-time data regarding which service providers offer the most reliable voice and data connections on the NH-70 route.
**Action Required**
No mandatory action, but consumers are encouraged to use the report to make informed choices regarding their service providers.
**TRAI (Regional Office Jaipur)**
**Impact**
The agency acts as the supervisor and disseminator of performance data to ensure regulatory transparency.
**Action Required**
The Regional Office remains the point of contact for clarifications and will continue to host the detailed report on the official TRAI website.

The Telecom Regulatory Authority of India (TRAI) has released findings of Independent Drive Test (IDT)
conducted on Munabao to Tanot National Highway (NH-70) 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 Munabao to Tanot National Highway (NH-
70) on 3rd June 2026 covering 311.4 KMs in Rajasthan LSA. These tests were 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 routes, 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.
