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
