TRAI Assesses Mobile Network Quality Across Hamirpur & Bilaspur and nearby areas Route under HP LSA

The Telecom Regulatory Authority of India (TRAI) has released findings of Independent Drive Test (IDT) conducted across Hamirpur & Bilaspur and nearby areas Route under HP LSA, during the month of May 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 analyzed in real-time using advanced Software Systems.

TRAI, through its appointed agency, conducted drive tests across Railway Drive from Chandigarh to Amb - 168.0 Km, Highway Drive - 119.0 Km, City drive – 290.6 Km, Hotspot locations - 08, Walk Test - 2.5 Km and Inter Operator Calling at 01 location during 12th May 2026 to 16th May 2026 in HP LSA. These tests were conducted under the supervision of the TRAI Regional Office Delhi. 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 Railway Drive, Highway Drive, City drive, Hotspots, Walk tests & Inter-operator calling, as per the legends shown on the map: -
