Telecom Regulatory Authority of India Measuring Telecom Services

Telecom Regulatory Authority of India Measuring Telecom Services By Asit Kadayan Advisor (Qo. S) Telecom Regulatory Authority of India (TRAI) 25 th October 2017 1

INDIA: Telecom • • 22 License Service Areas (LSAs) 12 Mobile operators in a LSA 8 Mobile operators present in 19 -22 LSAs Wireless Subscriber base of more than 1. 18 Billion and growing with quarterly growth rate of 1. 5% Tele-density of 92% Internet Subscribers 431 Millions 95% of Internet subscribers are from wireless networks Urban Teledensity 173% Rural Teledensity 57% Telecom Regulatory Authority of India (TRAI) DELHI 2 G 3 G 4 G LSA Subs. Market (Millions) share (%) Metros 120 10% Circle 'A' 413 35% Circle 'B' 474 40% Circle 'C' 179 15%

India’s Context • Regulatotry, Licensing and Legal Framework – 22 LSAs, Roaming scenarios within country, – Spectrum availability, Network Densification, Ro. W issues • About 410 Million Data subscribers: 127 (GSM), 1. 4 (CDMA), 121 (3 G), 159 (4 G) • 1. 5 Million Base Stations: 0. 7 Million (2 G), 0. 35 Million (3 G), 0. 5 Million (4 G) • Monthly Data Usage 1. 5 Exabytes: 0. 04 (2 G), 0. 26 (3 G), 1. 22 (4 G) • Data Network, – 98% on Wireless Networks, Broadband >512 kbps, Content from outside country – Avg. data usage per subscriber is 3. 9 GB: 0. 3 (GSM), 3. 7 (CDMA), 2. 2 (3 G), 8 (4 G) – Monthly ARPU about 1 USD, 0. 25 USD from data services • Level of Market Competition in Internet – 8 -10 Mobile Operators in LSA and several other operators (Cable, FTTH)

Revenue and Usage (April-June 2017) • Gross Revenue (GR) during the quarter: Rs. 64, 889 Crores • Adjusted Gross Revenue (AGR) during quarter: Rs. 39, 778 Crores • Share of PSU in Access AGR: 11. 26% • Monthly Average Revenue Per User (ARPU): rs. 83. 41 • Revenue to Government – License Fee – Spectrum Usage Charges 4

Interconnect Usage Charges (IUC) • IUC are wholesale charges payable by a TSP to another TSP, for terminating or transiting/carrying a call from its network to the network of the receiving TSP. The IUC mainly consists of termination charges, origination charges and carriage/transit charges. – Wireless to wireless 14 paise per minute – International incoming call to wireless and wireline 53 paise per minute – domestic carriage charge as 35 paise per minute. • The two most commonly used methods for estimation of domestic termination charges are (i) Fully Allocated Cost (FAC) Method and (ii) Long Run Incremental Cost (LRIC) Method. LRIC also has variants such as LRIC+ Method and pure LRIC Methods. 5

Qo. S Data • Network Related Data for – Availability, Accessibility, Maintainability – Collected as a part of PMR for 2 G, 3 G – 2 G Call Drop Rate is collected for Qo. S Analytics Portal • Customer Service Quality Data – Billing Credibility, Call Center Performance, Complaint resolution, Refunds – Collected as part of PMR for 2 G, 3 G and Basic services • Wireless Data – Minimum Throughput, Average Throughput – Collected as part of PMR – TRAI My. Speed 6

Qo. S Data • From whom it is to be collected – No. of Operators • 12 TSPs e. g. Airtel, Vodafone, Idea, BSNL/MTNL, Tata etc. • Some of these are exiting/ merging e. g. Quadrant, Vodafone, MTS, etc. • From Where it is to be collected – LSAs in operation • 6 TSPs having Pan-India (22 LSAs) License, • Others operating in few LSAs like BSNL in 21 LSAs, Telenor in 9 LSA, MTS in 6 LSA, MTNL in 2 LSAs – Radio Access Technologies (RATs) deployed • GSM, CDMA, WCDMA, LTE-TDD, LTE-FDD • Some TSPs deployed all/ Most of RATs/ Few RATs/ One RAT • RATs deployed varies LSA to LSA and may be operational at later stage 7

Other Crowd Sources (Voice) § § § Passive App Voice Quality Feedback Environement Inputs Perceived Quality Feedback from selected users e. g. Community based approach IVRS based Survey/ Inputs Coverage Maps § Areas which are not sufficiently covered through other measures Crowd Sourced Other Data Crowd Sources (Data) § § Passive App Data Speed Feedback Environement Inputs Regular feeddback from Railway/ Bus RF Drive Tests To corroborate observations § § § Identified Problem Areas e. g. CRM, CDR Analysis Enhanced RF Drive Test including Active/ Passive Tests of Data and Voice Environement Inputs Network KPIs Outcome § § § Unified Single View Service Oriented instead of Technology Oriented Observable Effects Vs. Expected Effects To correlate observations § § Identified Problem Areas Enhanced RF Drive Test including Active/ Passive Tests of Data and Voice
