Posted On: 02 JUN 2026 1:28PM by PIB Delhi TRAI Assesses Mobile Network Quality Across Palampur, Maranda, Bhawarna Khas, Panchrukhi, Majheran Khas, Paprola, Baijnath, Aweri, Sungal, Bharamat Uparli, Sornu, Khas Khalet, Pharer, Bindravan, Nagri, Arth Jhilki, Darang Khas, Malan, Gopalpur, Sukairi, Kandi & Saperu etc. in Palampur City & Nearby areas and highway Route from Chandigarh to Palampur passing through Bilaspur, Ghumarwin, Hamirpur & Bhawarna etc.

The Telecom Regulatory Authority of India (TRAI) has released findings of Independent Drive Test (IDT) conducted across Palampur City and Chandigarh to Palampur Highway Route under HP 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 usage environments like cities, hotspots, public transport hubs, etc. In this type of drive test, 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 – 197.4 KMs, Hotspot locations - 05, Walk Test - 1.6 Kms in Palampur City & nearby areas and Chandigarh to Palampur Highway Route - 242.1 Kms during 10th March 2026 to 13th March 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 in the areas/ route under test on the day/ time of conduct of the drive test.
