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 f indings 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 vo ice & data) p rovided

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 dat a

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 Cit y 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 of the TRAI Regional Office Hydera bad.

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 th e dri ve t est.

4. Drive Test Route Map: The following map prov ides overvi ew of drive test

routes indicating City drive, Inter-operator calling, Hotspots and Walk tests ,

5. Key Parameters Assessed

a) Coverage Gap: Percentage of samples, for which signa l 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 ca lls

out of the number of successfully established calls, we re 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 tota l

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 th e

map Annexed.
