The Telecom Regulatory Authority of India (TRAI) has released its independent drive test (IDT) findings for the Delhi licensed service area (LSA), covering extensive city routes during the month of July 2025. The drive tests, conducted under the supervision of the TRAI Regional Office, Delhi, were designed to capture real-world mobile network performance across diverse usage environments including urban zones, institutional hotspots, public transport hubs, and high-speed corridors.
Between July 9, 2025 to July 16, 2025, TRAI teams conducted detailed tests across 858.9 kilometre (km) of city drive test, 21 hotspot locations, 250 km of metro rail routes (Magenta Line, Voilet Line, Blue Line, Yellow Line, Red Line and Orange Line) and 03 km of walk test. Technologies evaluated included 2G, 3G, 4G, and 5G, reflecting the service experience of users across multiple handset capabilities. The findings of IDT have already been intimated to all the telecom service operators (TSPs) concerned.
The findings of the IDT have already been intimated to all the TSPs concerned. Key parameters assessed: a) Voice services: call setup success rate (CSSR), drop call rate (DCR), call setup time, call silence rate, speech quality (MOS), coverage. b) Data services: Download/upload throughput, latency, jitter, packet drop rate, and video streaming delay.
In the area, Bharti Airtel (Airtel), Mahanagar Telephone Nigam Limited (MTNL), Reliance Jio (Jio) and Vodafone Idea Limited (Vi) had 99.40 per cent, 35.29 per cent, 99.12 per cent and 99.10 per cent call setup success rate while drop call rate of 0.00 per cent, 14.64 per cent, 1.07 per cent and 0.06 per cent respectively in auto-selection mode (5G/4G/3G/2G).
Airtel, Jio and Vi have silence call rate of 0.61 per cent, 2.39 per cent and 3.37 per cent respectively in packet switched network (4G/5G) while Airtel, MTNL, Jio and Vi have average MOS of 3.96, 2.60, 3.77 and 4.30 respectively.
