For Immediate Release
TRAI Assesses Mobile Network Quality Across, city drive in Ganjam,
Gajapati and Rayagada districts on Odisha LSA.
The Telecom Regulatory Authority of India (TRAI) has released findings of
Independent Drive Test (IDT) conducted across city drive in Ganjam, Gajapati
and Rayagada districts on Odisha LSA., during the month of April 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 SG networks. Multiple advanced test handsets are used, and the
sessions are monitored and analysed in real-time using advanced Software
Systems.
3. TRAI, through its appointed agency, conducted drive tests across City drive
- 446 Kms, Hotspot locations - 8 in Ganjam, Gajapati and Rayagada districts
on Odisha LSA during 23rd April 2026 to 25th April 2026 in Odisha LSA. These
tests were conducted under the supervision ofthe TRAI Regional Office Hyderabad.
The observations presented in drive test reports represent the per formance of the
TSPs on the area/ route under test on the day/ time of conducting the drive test.
4. 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:

15. 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
6. The overall mobile network performance in Hyderabad for the key pa rameters
has been summarised below:
a) Coverage Gap -(i) 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 poor signal strength out of the total
samples collected, was 5648/37277 for Airtel, 14768/35428 for
BSNL, 4976/ 44323 for RJIL and 3910/ 17533 for VIL. Details of the
coverage gaps have been provided in the map Annexed.
(ii) 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 Limited service (No Coverage) out of the total
samples collected, was 6939/37277 for Airtel, 4807/35428 for BSNL,
975/ 44323 for RJIL and 13448/ 17533 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 10/325 for
Airtel, 33/308 for BSNL, 7/406 for RJIL and 0/ 156 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 23/340 for Airtel, 14/212 for BSNL 14/385 RJIL
and 17/137 for VIL. 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 81.74 Mbps for Airtel (5G/4G), 6.71 Mbps for
BSNL (3G), 186.07 Mbps for RJIL (5G/4G) and 17.91 Mbps for
VIL (SG/4G/2G). Detail of Download throughput has been provided
in the map Annexed.
ii) Data Upload performance (Overall): Average upload speed was
observed as 18.09 Mbps for Airtel (SG/4G), 3.54 Mbps for BSNL
(3G), 13.46Mbps for RJIL (SG/4G) and 9.63 Mbps for VIL
(SG/4G/2G). Detail of Upload throughput has been provided in the
map Annexed.
