TRAI Assesses Mobile Network Quality on Delhi–Agra Routes via Yamuna Expressway and Rail Route under Delhi LSA.

Information Note to the Press (Press Release No. 123 / 2026) TELECOM REGULATORY AUTHORITY OF INDIA www.trai.gov.in New Delhi, 28 Sep 2026 For Immediate Release TRAI Assesses Mobile Network Quality along the Delhi to Agra via Yamuna Expressway passing through Dankaur, Jewar, Tappal, Surir, Javara, Baldeo, Khandauli, Kuberpur etc. and Agra to Delhi passing through Raja Ki Mandi Jn, Mathura Jn, Chata, Kosi Kalan, Palwal, Ballabhgarh, Faridabad etc. under Delhi LSA.

The Telecom Regulatory Authority of India (TRAI) has released findings of Independent Drive Test (IDT) conducted along the Delhi-Agra Highway route and Agra-Delhi Railway route under Delhi LSA, during the month of Jul 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.

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 analyzed in real-time using advanced Software Systems.

3. TRAI, through its appointed agency, conducted drive tests across Highway drive – 183.4 Km, Hotspot location – 01 and Railway Drive – 188 Km during 16th Jul 2026 to 17th Jul 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. Drive test routes: The map provides overview of drive test routes indicating, hotspot test, highway and railway drive route as per the legends shown on the map.
