**Executive Summary**
The Telecom Regulatory Authority of India (TRAI) released findings from an Independent Drive Test (IDT) conducted between May 4 and May 8, 2026, to assess mobile network quality in Gorakhpur City and the Lucknow-to-Gorakhpur railway route. The report evaluates voice and data services across major Telecom Service Providers (TSPs), identifying significant gaps in coverage and quality of service. Findings have been shared with TSPs to facilitate necessary service improvements.
**Key Points / Main Content**
* **Scope and Methodology**
* Tests covered 342.1 KM of city drive, 11 hotspot locations, 3.7 KM of walk tests, and 296.3 KM of railway routes under the UPE License Service Area (LSA).
* The assessment included 2G, 3G, 4G, and 5G networks using live SIM cards from all TSPs: Airtel, BSNL, RJIL (Jio), and VIL (Vodafone Idea).
* Performance was measured via parameters such as Call Drop Rate (CDR), Call Setup Success Rate (CSSR), and data throughput (Download/Upload).
* **Voice Quality and Coverage Findings**
* **Coverage Gaps:** BSNL recorded the highest number of poor signal samples in both Gorakhpur City (13,582) and the railway route (6,247). RJIL and Airtel showed the lowest coverage gaps in these areas.
* **Dropped Calls:** In Gorakhpur City, BSNL recorded 22 dropped calls out of 431, while Airtel recorded only 1 out of 453. On the railway route, BSNL had 25 dropped calls, whereas Airtel and VIL had 2 each.
* **Call Silence:** Airtel and VIL recorded 18 instances of call silence exceeding 3 seconds in Gorakhpur City; RJIL recorded 6 instances.
* **Data Performance Results**
* **Download Speed (City):** RJIL provided the highest average download speed at 204.44 Mbps, followed by Airtel (116.48 Mbps) and VIL (64.50 Mbps). BSNL recorded the lowest speed at 5.54 Mbps.
* **Download Speed (Railway):** RJIL led with 66.38 Mbps, while BSNL remained the lowest at 5.53 Mbps.
* **Upload Speed:** Airtel recorded the highest average upload speeds in both the city (21.49 Mbps) and the railway route (10.28 Mbps). BSNL consistently recorded the lowest upload speeds (under 3.1 Mbps).
**Impact Analysis**
**Telecom Service Providers (Airtel, BSNL, RJIL, VIL)**
**Impact**
The report identifies specific geographical locations and technical parameters where each TSP is failing to meet Quality of Service (QoS) standards, particularly regarding signal strength and call stability.
**Action Required**
TSPs must review the shared findings and take necessary corrective actions to improve network performance and address identified coverage gaps.
**General Telecom Consumers**
**Impact**
Consumers are provided with transparent, real-time data regarding the actual performance of mobile networks in their region to help inform service choices.
**Action Required**
No direct action is required, though consumers may use the data to evaluate their current service providers.
**TRAI Regional Office (Bhopal)**
**Impact**
Responsible for the supervision of the tests and providing clarification on the data through its regional contact points.
**Action Required**
Continue monitoring TSP performance and provide public access to detailed IDT reports via the official TRAI website.

TRAI Assesses Mobile Network Quality Across
Gorakhpur City and Lucknow to Gorakhpur
Railway route under UPE LSA
प्रव तथ: 16 JUN 2026 3:06PM by PIB Delhi
TRAI assesses Mobile Network Quality Across Gorakhnath, Jhungiya, Ratanpur, Pipraich, Rampur
Buzurg, Bhathat, Mangalpur, Delhi Public School, Gorakhpur, Govindpur, Kaalesar, Belghat, Madapar,
Gorakhpur Airport, Taramandal, Ramjanki Nagar and Shahpur in Gorakhpur City & nearby areas.
The Telecom Regulatory Authority of India (TRAI) has released findings of Independent Drive Test (IDT)
conducted across Gorakhpur City and Lucknow to Gorakhpur Railway route under UPE 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.
These IDTs have been designed to capture on ground mobile network performance of all TSPs across
diverse usage environments 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.
TRAI, through its appointed agency, conducted drive tests across City drive – 342.1 KMs, Hotspot
locations - 11, Walk Test – 3.7 Kms and Railway – 296.3 Kms in Gorakhpur city and Lucknow to
Gorakhpur Railway route during 4th May 2026 to 8th May 2026 in UPE LSA. These tests were conducted
under the supervision of the TRAI Regional Office Bhopal. 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.
