For Immediate Release

TRAI Assesses Mobile Network Quality on Munabao to Tanot National

Highway (NH-70) in Rajasthan LSA.

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.

2. 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.

3. Earlier, the National Highway Authority of India (NHAI) had identified mobile network

coverage gaps (black spots) along various National Highways, including the

Munabao–Tanot route, and brought the matter to the notice of TRAI. Accordingly, an

independent assessment of mobile network coverage along this route has been

planned.

4. 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.

5. Drive Test Route Map: The following map provides overview of drive test routes, as

per the legends shown on the map: -

6. 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.

7. The overall mobile network performance on Munabao to Tanot National Highway

(NH-70) 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 no coverage out of the total samples collected,

was 5728/14130 for Airtel, 8509/10174 for BSNL, 881/14701 for RJIL

and 9227/11286 for VIL. & poor signal strength out of the total samples

collected, was 5271/14130 for Airtel, 793/10174 for BSNL, 4403/14701

for RJIL and 1561/11286 for VIL. Details of the coverage gaps have been

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 10/48 for Airtel,

2/6 for BSNL, 3/76 for RJIL and 1/8 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 4/32 for Airtel, 2/7 for BSNL, 8/68 for RJIL. For VIL

the call silence rate could not be captured due non availability of

4G/5G Network. 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 42.83 Mbps for Airtel (5G/4G), 3.49 Mbps for

BSNL (4G/3G/2G), 55.05 Mbps for RJIL (5G/4G) and 0.35 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 14.03 Mbps for Airtel (5G/4G), 2.80 Mbps for BSNL

(4G/3G/2G), 7.01 Mbps for RJIL (5G/4G) and 0.75 Mbps for VIL

(5G/4G/2G). Detail of upload throughput has been provided in the

map Annexed.

8. Details of drive test route and area covered during the IDT are as under: -

Highway Route- Munabao to Tanot Via NH-70 passing through Sundra, Myajlar,

Gunjangarh, Bandha, Longewala and Sadhawala etc.

9. The findings of this IDT report have been shared with respective TSPs for

taking further necessary action at their end, if required. Detailed report of IDT

is made available on the TRAI website at www.trai.gov.in. For any clarification

or additional information, an email can be sent to Regional office of TRAI at
