TRAI Assesses Network Quality Across Kochi City

TRAI Assesses Network Quality Across Kochi City

The Telecom Regulatory Authority of India (TRAI) has released its Independent Drive Test (IDT) findings for the Kochi City, Kerala Licensed Service Area (LSA), covering extensive city and highway routes during the month of July 2025. The drive tests, conducted under the supervision of the TRAI Regional Office, Bengaluru, were designed to capture real-world mobile network performance across diverse usage environments – urban zones, institutional hotspots, public transport hubs, and high-speed corridors.

Between 30^th Jun 2025 to 03^rd July 2025, TRAI teams conducted detailed tests across Kochi City and surrounding areas including 231.4 Kms of City drive, Coastal drive of 8.3 Kms (Marine Drive Park to Marine Drive Jetty), Walk Test of 8.8 Kms and 08 Hot spots segments. 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 Telecom Service Providers (TSPs) concerned for further necessary action.

In Kochi, the assessment included high-density neighbourhoods like Koonammayu, Nearby North Paravur, Varapuzha, Edavanakkad, Vaduthala, Kakkanad, Perumpilly, South Paravoor, Panambukad Colony, Kumbalam, Ernakulam Junction, Ponnurunni East and Vaduthala etc.

TRAI also evaluated real-world conditions at 08 static hotspots—including Aluva Metro Station, Cochin University, General Hospital, High Court, Info Park, International Airport Kochi, Kaloor Stadium and Wonderla Amusement Park – to reflect stationary user experience.

The Coastal route covered from Marine Drive Park to Marine Drive Jetty, capturing mobile network behaviour in Coastal area.

The walk tests, conducted on 02 July and 03 July 2025, focused on Ernakulam South Railway Station, Fort Kochi, KSRTC Bus Stand, and Marine Drive, capturing mobile network behaviour in crowded pedestrian environments.

The tests were conducted using TRAI-calibrated equipment and standardised protocols in real-time environments. The detailed report is available at TRAI website www.trai.gov.in.
