3. India’s Context Regulatotry, Licensing and Legal Framework
22 LSAs, Roaming scenarios within country,
Spectrum availability, Network Densification, RoW issues
About 410 Million Data subscribers: 127 (GSM), 1.4 (CDMA), 121 (3G), 159 (4G)
1.5 Million Base Stations: 0.7 Million (2G), 0.35 Million (3G), 0.5 Million (4G)
Monthly Data Usage 1.5 Exabytes: 0.04 (2G), 0.26 (3G), (4G)
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 (3G), 8 (4G)
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)

4. 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

License Fee
Spectrum Usage Charges

5. 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.

7. QoS 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
