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

3. Coverage Details
RF Coverage relates to the geographical footprint within the system that has sufficient RF signal strength to provide for a call/data
session. The Coverage rate of an operator is calculated basis of % of samples in which the Rx level is better than -85 dBm. The details
are as follows.

4. Receive (Rx) Quality Details
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%.

5. City-Level Ranking and KPI details
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
