TRAI Assesses Mobile Network Quality Across cities and adjoining areas of East Jaintia Hills and West Jaintia Hills Districts and from Ratha Cherre Khasia Punjee to Jowai along NH-6 in the State of Meghalaya under North East LSA

Information Note to the Press (Press Release No 70/ 2026) TELECOM REGULATORY AUTHORITY OF INDIA www.trai.gov.in New Delhi, 811i June 2026 For Immediate Release TRAI Assesses Mobile Network Quality Across cities and adjoining areas ofEast Jaintia Hills and West Jaintia Hills Districts and from Ratha Cherre Khasia Punjee to Jowai along NH-6 in the State of Meghalaya under North East LSA.

The Telecom Regulatory Authority of India (TRAI) has released findings of Independent Drive Test (IDT) conducted across East Jaintia Hills and West Jaintia Hills Districts and from Ratha Cherre Khasia Punjee to Jowai along NH-6 in the State of Meghalaya under North East LSA, during the month ofMarch 2026, for information of general telecom consumers. The purpose ofthis drive test is to assess and verify real time quality ofmobile network services (both voice & data) provided by Telecom Service Providers (TSPs). During the IDT, TRAI captures performance ofTSPs for key Quality ofService (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. TRAI, through its appointed agency, conducted drive tests across City drive - 213.0 KMs, Highway drive- 98.9 Kms, Hotspot locations - I 0, Walk Test - 0.5 Kms in Meghalaya State during 11 111 March 2026 to 16th March 2026 in North East LSA. These tests were conducted under the supervision of the TRAI Regional Office Kolkata. The observations presented in drive test reports represent the performance ofthe TSPs on the area/ route under test on the day/ time ofconducting the drive test.

4. Drive Test Route Map: The following map provides overview ofdrive test routes indicating City drive, Inter-operator calling, Hotspots and Walk tests, as per the legends shown on the map: - Leaends I City Hotspot W•lk T•st Htchw•v5. 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).
