TRAI Assessed Mobile Network Quality Across in North Delhi and nearby areas.

Information Note to the Press (Press Release No. 82 /2026) TELECOM REGULATORY AUTHORITY OF INDIA www.trai.gov.in New Delhi, 01 July 2026 For Immediate Release TRAI Assessed Mobile Network Quality Across Jaunti, Kanjhawala, Bawana, Bakoli, Alipur, Rohini, Karala, Shastri Park, Burari, Shalimar Bagh, Mukherjee Nagar, Wazirabad, Ashok Nagar, Paschim Vihar and Janakpuri etc. in North Delhi and nearby areas. The Telecom Regulatory Authority of India (TRAI) has released findings of Independent Drive Test (IDT) conducted across North Delhi and nearby areas Route under Delhi LSA, during the month of Apr 2026, for information of general telecom consumers. The purpose of this drive test was to assess and verify real time quality of mobile network services (both voice & data) provided by Telecom Service Providers (TSPs). During the IDT, TRAI captured 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 being 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 – 374.2 Kms, Hotspot locations - 13, Walk Test - 7.0 Kms and Airport Route - 57.8 Kms during 13th Apr 2026 to 17th Apr 2026 in Delhi 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. 4 .
