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: -
Pa ge 1 | 3AU-3/(3)/2025-RO_JPR-Part(1) I/42958/2026
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.
Locations of Dropped Calls and Call Silence instances can be seen by

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
Jaipur on Email id adv.jaipur@trai.gov.in Regional Office of TRAI at Jaipur
