TRAI has released its latest independent mobile network drive-test results for the Delhi–Agra route via the Yamuna Expressway and Agra–Delhi railway corridor. The July 2026 assessment found major differences between operators across download speeds, signal quality and dropped calls, with Jio recording the highest highway download speed and Vi recording the lowest poor-signal share.
Jio Records 213.68 Mbps on Yamuna Expressway
TRAI’s test covered 183.4 km of the Delhi–Agra highway route and was conducted on July 16 and 17, 2026. Reliance Jio recorded a peak measured average download throughput of 213.68 Mbps, followed by Airtel at 135.33 Mbps, Vodafone Idea at 46.48 Mbps and BSNL at 8.10 Mbps.
Jio also recorded the highest upload throughput on the highway at 20.62 Mbps. Airtel followed with 17.62 Mbps, while Vi and BSNL recorded 13.70 Mbps and 3.38 Mbps respectively.
The results represent measurements taken along the specific route and testing period. They should not be treated as guaranteed speeds for every subscriber travelling on the Yamuna Expressway.
Vi Records Lowest Poor-Signal Share
Download speed was not the only area where the operators differed. Vi recorded 44 poor-signal samples out of 13,327 measured samples, giving it a poor-signal share of about 0.33%.
Jio recorded 145 poor-signal samples from 13,268, or about 1.09%, while Airtel recorded 180 from 13,960, or around 1.29%. BSNL had 4,876 poor-signal samples from 12,619, equivalent to about 38.64%.
TRAI also recorded 206 BSNL samples with limited service or no coverage on the highway route. Airtel, Jio and Vi recorded zero such samples in this particular measurement.
Vi Had Zero Dropped Calls on the Highway
Vi recorded zero dropped calls among 66 successfully established calls during the highway test. Jio recorded one dropped call from 66 calls, while Airtel had two dropped calls from 65 calls.
BSNL recorded 16 dropped calls from 68 successfully established calls. Based on those test samples, the calculated drop rates were 0% for Vi, about 1.52% for Jio, 3.08% for Airtel and 23.53% for BSNL.
These figures are route-specific measurements and should not be interpreted as an assessment of each operator’s overall national or Delhi-circle performance.
Jio Also Leads Download Speed on the Railway Route
TRAI separately tested 188 km of the Agra–Delhi railway corridor. Jio again recorded the highest download speed, at 82.68 Mbps.
Vi recorded 47.48 Mbps, Airtel 44.23 Mbps and BSNL 9.99 Mbps. Airtel, however, recorded the highest upload speed on the railway route at 13.32 Mbps, followed by Vi at 12.31 Mbps, Jio at 10.14 Mbps and BSNL at 5.07 Mbps.
The railway results also produced a different call-performance picture. Airtel recorded zero dropped calls among 60 successfully established calls, while Vi had two drops from 62 calls, Jio had three from 63 and BSNL had 12 from 60.
TRAI Also Audits South Delhi and Nearby Areas
A separate TRAI drive test covered more than 310 km across South Delhi and nearby areas, including parts of Noida. The July 6–10 assessment covered locations including Dwarka, Uttam Nagar, Janakpuri, Mahipalpur, Malviya Nagar, Saket, Lajpat Nagar, Naraina, Patel Nagar, Karol Bagh and Mayur Vihar.
Jio recorded the highest download throughput in that test at 257.03 Mbps. Airtel followed at 176.82 Mbps, while Vi recorded 35.07 Mbps and MTNL 4.69 Mbps. Airtel recorded the highest upload speed at 24.83 Mbps, ahead of Vi at 20.70 Mbps and Jio at 18.98 Mbps.
Jio also recorded the lowest calculated call-drop rate among the operators tested in South Delhi, with one dropped call from 684 successfully established calls, or about 0.15%. Airtel and Vi each recorded about 0.44%, while MTNL recorded about 15%.
Network Performance Varies by Location and Metric
The two TRAI assessments show why mobile network quality cannot be judged using download speed alone. An operator can record the highest data throughput while another records a lower poor-signal ratio or different call-performance results on the same route.
For the Delhi–Agra highway test, Jio’s measured download speed was the highest, while Vi recorded the lowest poor-signal share and zero dropped calls in the tested sample. On the railway route, Airtel recorded zero dropped calls, while Jio remained ahead on download speed.
TRAI’s independent drive-test programme provides route-level measurements that can be useful for understanding network behaviour during travel, but the results remain a snapshot of the locations, dates and conditions under which the tests were conducted.
The reports were officially released by TRAI on September 28 as Press Release Nos. 123 and 124, covering the Delhi–Agra route and South Delhi respectively.
