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.

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 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, 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.

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.

TRAI, through its appointed agency, conducted drive tests across City drive – 213.0 KMs, Highway drive- 98.9 Kms, Hotspot locations – 10, Walk Test – 0.5 Kms in Meghalaya State during 11^th March 2026 to 16^th 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 of the TSPs on the area/ route under test on the day/ time of conducting the drive test.

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: –

Key Parameters Assessed

1. Coverage Gap: Percentage of samples, for which signal strength observed less than the minimum prescribed signal strength for respective technology (2G/ 3G/ 4G/ 5G).
2. Voice Services: Call Setup Success Rate (CSSR), Drop Call Rate (DCR), Call Setup Time, Call Silence Rate, Speech Quality (MOS).
3. Call Silence Instance: Number of call silence instance occurred during the calls.
4. Data Servies: Download/ Upload Throughput, Latency, Jitter, Packet Drop Rate

The overall mobile network performance in East Jaintia Hills and West Jaintia Hills Districts and from Ratha Cherre Khasia Punjee to Jowai along NH-6 for the key parameters has been summarised below: –

a)    Coverage Gap – The signal strength observed during voice testing on the city drive test route and highway 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 as detailed below-

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 as shown below.

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 as shown below-

Details of the call silence instance locations have been provided in the map Annexed.
