The Telecom Regulatory Authority of India (TRAI) has conducted Independent Drive Tests (IDT) covering Hardoi & Shahjahanpur Cities and nearby areas and Varanasi to Prayagraj Railway Route of UP (East) LSA during the month of 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^th February to 20^th 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 all the TSPs concerned for further necessary action.
