2 Appendix 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 29 th August 2016 to 30 th 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 29 th to 30 th of August 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 shown in the below map.

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. 10

13 Appendix Ancillary Details 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 % KPI Distribution 75.00% 50.00% 25.00% 0.00% Coverage % Accessibility % Retainability % Mobility % Rx Quality % Aircel 2G 59.11% 81.31% 94.25% 95.85% 95.27% Airtel 2G 70.14% 95.40% 97.19% 97.22% 94.95% Airtel 3G 57.77% 96.46% 96.79% 99.64% 98.15% BSNL 2G 67.61% 84.79% 91.48% 87.58% 88.85% BSNL 3G 37.21% 87.16% 91.05% 91.65% 97.65% IDEA 2G 70.25% 98.21% 98.64% 98.79% 97.45% IDEA 3G 61.65% 98.96% 96.84% 99.69% 97.21% Reliance 2G 49.97% 89.37% 96.04% 96.73% 92.45% Reliance 3G 51.12% 89.47% 91.91% 98.71% 98.82% TATA 2G 72.85% 81.40% 93.14% 96.44% 94.16% TATA 3G 61.35% 85.64% 93.17% 98.05% 96.45% TATA CDMA 49.47% 61.19% 91.87% % 78.19% Telenor 2G 26.39% 82.61% 78.95% % 80.84% Vodafone 2G 62.41% 97.56% 98.33% 98.41% 96.25% Vodafone 3G 53.59% 97.74% 98.15% 99.77% 97.69% 12

Receive (Rx) Quality Details Appendix 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%.

City-Level Ranking and KPI details Appendix 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: *In case of multiple call failure in similar geo location in given period of 60sec has been counted as one call failure Operator Total Call Attempt Blocked Calls Blocked Call Rate* CSSR Aircel 2G % 81.31% Airtel 2G % 95.40% Airtel 3G % 96.46% BSNL 2G % 84.79% BSNL 3G % 87.16% IDEA 2G % 98.21% IDEA 3G % 98.96% Reliance 2G % 89.37% Reliance 3G % 89.47% TATA 2G % 81.40% TATA 3G % 85.64% TATA CDMA % 61.19% Telenor 2G % 82.61% Vodafone 2G % 97.56% Vodafone 3G % 97.74% 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 Operator Total Call Established Total Call Drop CDR CCSR Aircel 2G % 94.25% Airtel 2G % 97.19% Airtel 3G % 96.79% BSNL 2G % 91.48% BSNL 3G % 91.05% IDEA 2G % 98.64% IDEA 3G % 96.84% Reliance 2G % 96.04% Reliance 3G % 91.91% TATA 2G % 93.14% TATA 3G % 93.17% TATA CDMA % 91.87% Telenor 2G % 78.95% Vodafone 2G % 98.33% Vodafone 3G % 98.15% 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 Operators Total HO Attempt HO Failure HO Success HO Failure Rate HO Success Rate Aircel 2G % 95.85% Airtel 2G % 97.22% Airtel 3G % 99.64% BSNL 2G % 87.58% BSNL 3G % 91.65% IDEA 2G % 98.79% IDEA 3G % 99.69% Reliance 2G % 96.73% Reliance 3G % 98.71% TATA 2G % 96.44% TATA 3G % 98.05% TATA CDMA % % Telenor 2G % % Vodafone 2G % 98.41% Operators not meeting Vodafone benchmark 3G % 99.77% 17
