Independent Drive Test Report

- August’16

Nagpur to Bhopal Highway

Key performance indicators for most of the operators: Most of the operators failed to meet the Call

Setup Success Rate (CSSR) benchmark, where as most of the operators fall below the 2% Call

Dropped Rate (CDR) threshold.

Methodology:

Independent Drive test was conducted in Nagpur to Bhopal Highway from 9:00 AM to 9:PM from 29th to 30th of August 2016. The total drive test

covered in Nagpur to Bhopal highway area was approximately 350 km over a period of 2 days. A total of ~3098 calls were made for eight 2G

networks, six 3G networks and one CDMA networks covering eight operators

Introduction

Ancillary Details

Overview

TRAI is regularly monitoring the performance of Telecom Service Providers (TSP) against the benchmarks for the various Quality of

Service (QoS) parameters laid down by the Authority. TSPs submit Performance Monitoring Reports to TRAI every quarter. TRAI also

undertakes audit and assessment of Quality of Service through independent agencies to verify the Quality of Service claimed. The Audit

agencies conduct sample ‘Drive tests’ across various cities all over the country as part of audit and assessment of the TSPs’

performance

In view of complaints on call drops and other network issues, on behalf of TRAI, an Independent Drive Test (IDT) was conducted from

29th August 2016 to 30th August 2016 covering various locations in Nagpur to Bhopal Highway . The performance of Aircel, Airtel,

BSNL, Idea, Vodafone, Reliance, Tata, Telenor was monitored across various technologies (2G, 3G and CDMA). The drive test route was

defined on the basis of several factors that include - areas from where call drop complaints are commonly received; areas of heavy

usage; residential areas away from arterial roads; office areas; areas where previous Drive tests showed network issues; etc.

For the purpose of these tests, 2G + 3G Mode (Auto) was used. The test results obtained from these drive tests were conducted to

assess the network condition more specifically in terms of Radio Frequency (RF) Coverage; Rx Quality; Call Setup Success Rate; Call

Drop Rate; Blocked Calls and Carrier to Interference ratio.

Drive Route Details For Goa Area:

Independent Drive test was conducted in Nagpur to Bhopal area from 9:00 AM to 9:PM from 29th to 30th of August 2016. The total

drive test covered in Goa area was approximately 350 km over a period of 2 days. Total of ~3098 calls were made for eight 2G

networks, six 3G networks and one CDMA networks covering eight operators. Roads and Areas covered in Nagpur to Bhopal Highway is

Detailed Analysis of Operators

High RLT

• Radio Link Timeout (RLT indicates how long the call can

sustain during poor quality – Higher the value the

longer it will sustain the call). Higher the RLT, poorer the

consumer experience during the call.

4. Summary & Highlights

Summary & Highlights

Most of the operators failed to meet the Call Drop Rate Benchmark of <=2% except Idea 2G , Voda 2G

& Voda 3G.

Key Highlights

• All the operators are failed to meet the Call Drop Rate benchmark of <=2%, except Idea and Vodafone.

• Aircel 2G, BSNL 2G & 3G, Reliance 3G and TATA 2G, Tata 3G, Tata CDMA and Telenor 2G failed to meet the

benchmark by a wide margin of >5%

• BSNL 2G & 3G, Reliance 3G, TATA CDMA and Telenor 2G have Call Drop Rates in the range of above 7%. These high

drop rates of operator is clearly indicating for urgent need of improvement in order to deliver reasonable levels of

services.

• Huge gap between the performances of Idea (2G) and Vodafone(2G&3G) compared to the poor performances of

other operators are clearly showing in the areas driven. There are possibilities for other operators to offer a better

Quality of service than currently is being provided.

2. Benchmarking KPI Details

RF Coverage

RF Coverage relates to the geographical footprint within the system that has sufficient RF signal strength to provide for a call/data

session. Coverage rate of an operator is calculated basis of % of samples in which the Rx level is better than -85 dBm

Accessibility

Accessibility is the ability of a service to be obtained within specific tolerances and other given conditions, when requested by the user.

In other words, the ability of a user to obtain the requested service from the system. Accessibility is monitored by measuring Call Setup

Success Rate (CSSR) which is defined as the ratio of Established Calls to Call Attempts

Retainability

Retainability is “The ability of a service, once obtained, to continue to be provided under given conditions for a requested duration.” For

determining the Retainability the regulation prescribes three important parameters namely Call Drop Rate (CDR), Worst affected Cells

having more than 3% TCH drop and Connection with good voice quality. Drop Call and Connection with good voice quality were

monitored by the drive test

Mobility

In a cellular system a base station has only a limited coverage area. Hence it is possible for a moving subscriber to be out of range of a

base station while making a call. The process by which a mobile telephone call is transferred from one base station to another as the

subscriber passes the boundary of a cell is called a handover. The Handover success rate (HOSR) more than 95% is considered to be

good

Rx Quality

For measuring voice quality, RxQual samples on a scale from 0 to 7 for GSM operators, EcNo from 0 to -30 dBm and Frame Error Rate

(FERs) for CDMA service providers are measured. As per the QoS norms, RxQual between 0- 5 for GSM operators, EcNo >= -15 dBm and

between 0-4% FER value for CDMA operators FERs is considered to be good, where as RxQual beyond this benchmark is considered to

be bad

For measuring voice quality, RxQual samples on a scale from 0 to 7 for GSM operators, EcNo for 3G operators on a scale of 0 to -30

dBm and Frame Error Rate (FERs) for CDMA service providers are measured. As per the QoS norms, Rx Quality between 0- 5 for GSM

operators, EcNo >= -15 dBm and between 0-4% FER value for CDMA operators FERs is considered to be good, where as quality beyond

this benchmark is considered to be bad. The benchmark should usually be > =95%.

Accessibility is the ability of a service to be obtained within specific tolerances and other given conditions, when requested by the user.

In other words, the ability of a user to obtain the requested service from the system. Accessibility is monitored by measuring Call Setup

Success Rate (CSSR) which is defined as the ratio of Established Calls to Call Attempts. The benchmark is >=95%. The details are as

follows:

Retainability is “the ability of a service, once obtained, to continue to be provided under given conditions for a requested duration.” For

determining the Retainability, the regulation prescribes three important parameters namely Call drop rate (CDR), Worst affected Cells

having more than 3% TCH drop and Connection with good voice quality. The call drop and connection with good voice quality were

monitored by the drive test

Call Drop Rate (CDR): The parameter gives a reliable measurement of the mobile network used by the service provider for maintaining a

call once it has been correctly established

Mobility: In a cellular system a base station has only a limited coverage area. Hence it is possible for a moving subscriber to get out of

reach of a base station while making a call. The process by which a mobile telephone call is transferred from one base station to

another as the subscriber passes the boundary of a cell is called a handover. The Handover Ssuccess Rate (HOSR) more than 95% is

considered to be good

*In case of multiple call failure in similar geo location in given period of 60sec has been counted as one call failure
