For Immediate Release
TRAI Assesses Mobile Network Quality Across, City - Vavilalapally, Vidyanagar, Ashoknagar,
Mukarampura, Vemulawada, B.Y. Nagar, Rajanna Sircilla, Bejjanki, Koheda, Husnabad etc in
Karimnagar and surrounding towns.
Highway - Karimnagar-Vemulawada-Siricilla and Karimnagar-Bejjanki-Husnabad-Mulkanoor
Elkaturthy-Huzurabad- Karimnagar. Passing through Siddipet bypass, Samudrala and
Kesavapatnam etc ..
The Telecom Regulatory Authority oflndia (TRAI) has released findings oflndependent
Drive Test (IDT) conducted across Karimnagar City and Highway under AP LSA, during the
month of May 2026, for information of general telecom consumers. The purpose of this drive
test is to assess and verify real time quality of mobile network services (both voice & data)
provided by Telecom Service Providers (TSPs ). During the IDT, TRAI captures performance of
TSPs for key Quality of Service (QoS) parameters like Coverage, Call Drop Rate (CDR), Call
Setup Success Rate (CSSR), data Download (DL) and Upload (UL) throughput etc., which are
then published to inform Consumers and encourage TSPs to improve their services.
2. These IDTs have been designed to capture on ground mobile network performance ofall TSPs
across diverse usages environment like cities, hotspots, public transport hubs, etc. In this
type of drive testing, live data and voice sessions are established using SIM cards from all
TSPs over 2G, 3G, 4G, and 5G networks. Multiple advanced test handsets are used, and the
sessions are monitored and analysed in real-time using advanced Software Systems.
3. TRAI, through its appointed agency, conducted drive tests across City drive - 136.3 Krns,
Hotspot locations - 3, Highway - 217.2 Krns in Karimnagar and surrounding towns and
Karimnagar-Vemulawada-Siricilla and Karimnagar-Bejjanki- Husnabad- Mulkanoor
Elkaturthy-Huzurabad- Karimnagar -Highway during 1 lth May 2026 to 12th May 2026 in
Andhra Pradesh LSA. These tests were conducted under the supervision of the TRAI
Regional Office Hyderabad. The observations presented in drive test reports represent the
performance of the TSPs on the area/ route under test on the day/ time of conducting the
drive test.
4. Drive Test Route Map: The following map provides overview of drive test routes indicating
City drive and Highway and Hotspots as per the legends shown on the map:
