Information Note to the Press (Press Release No eb'1./2026) TELECOM REGULATORY AUTHORITY OF INDIA www.trai.gov.in Regional Office Bhopal, june'2026 For Immediate Release TRAI Assesses Mobile Network Quality Across Gopal ganj, Berkhari Guru, udaipura Tiwari, Pipariya Ramwan, Sironja, Bamhori bika, Lidhorahat, Bamora, Makronia, Makronia muhal, Guru amar das nagar, Gadoli khurd, Anand Nagar, Badona, Rajauya, Keshav Ganj, Motinagar and Katra bazar etc.

in Sagar city and khairpur, Mauhpali, Kachhar, Kotra, Kosamnara, Keio Vihar, Urdana, Barliya, Tumidih, Chandni chowk, Darogapara and Chakradhar Nagar etc. in Raigarh city.

The Telecom Regulatory Authority of India (TRAI) has released findings of Independent Drive Test (IDT) conducted across Sagar and Raigarh City under MP LSA, during the month of March 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, Ca ll 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 - 455.1 KMs, Hotspot locations - 16, Walk Test - 9. 7 Kms in Sagar and Ra igarh city during 16th March 2026 to 21st March 2026 in MP LSA. These tests were conducted under the supervision of the TRAI Regional Office Bhopal. 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.

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: ­legends City lnteroperator Hotspot walk test
