Independent Drive Test Report
- September’16
Surat
Key performance indicators for most of the operators: Most of the operators met the Call Setup
Success Rate (CSSR), where as half of the operators fall below the 2% Call Drop Rate (CDR)
threshold
Methodology:
Independent Drive test was conducted in Surat from 9:00 AM to 9:PM from 19th to 20th of September 2016. The total drive test covered in Surat
area was approximately 250 km over a period of 2 days. A total of ~3282 calls were made for seven 2G networks, five 3G networks and two
CDMA networks covering eight operators.

Introduction
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
19th September 2016 to 20th September 2016 covering various locations in Surat . The performance of Airtel, BSNL, Idea, MTS, Tata,
Vodafone, Reliance, 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 Mumbai to Goa area from 9:00 AM to 9:PM from 19th to 20th of September 2016. The total
drive test covered in Surat area was approximately 250 km over a period of 2 days. Total of ~282 calls were made for seven 2G
networks, five 3G networks & 2 CDMA networks covering eight operators.

Summary & Highlights
Half of the operators failed to meet the call drop rate benchmark of <=2%, except Airtel 2G, Airtel 3G,
BSNL 2G, Idea 2G, MTS CDMA, Vodafone 2G and Vodafone 3G.
Key Highlights
• All of the operators have shown improvement in their performance, compare to the pervious drive except Tata CDMA .
• Half of the operators failed to meet the call drop rate benchmark of <=2%, except Airtel 2G, Airtel 3G, BSNL 2G, Idea
2G, MTS CDMA, Vodafone 2G and Vodafone 3G.
• BSNL 3G, Reliance 2G and Telenor 2G operators have call drop rate of >5%.
• The gap between the performances of Airtel 2G, Airtel 3G, BSNL 2G, Idea 2G, MTS CDMA, Vodafone 2G and
Vodafone 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 is currently 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
