February 2026. The IDT have been designed to capture real-world mobile network
performance across diverse usage environments -Urban zones, hotspots, public
transport hubs etc.
TRAI, through its appointed agency, conducted detailed drive tests of 426.0 Kms of
City test, 123.2 Kms of Railway test and 4.2 kms of walk test in Hardoi &
Shahjahanpur Cities and Varanasi to Prayagraj Railway during 16" February to
20n February '2026. Technologies evaluated included 2G, 3G, 4G, and 5G,
reflecting the service experience of users across multiple handset capabilities. The
findings of IDT have been intimated to al| the TSPs concerned for further
necessary action.
