TRAI Assesses Mobile Network Quality Across, city drive in Ganjam, Gajapati and Rayagada districts on Odisha LSA.

Information Note to the Press (Press Release No~/2026) TELECOM REGULATORY AUTHORITY OF INbIA www.trai.~ov.in Hyderabad, '-{;f-1 2026 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,

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

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.
