Tata Communications launched WiMAX services in India in 2007, becoming one of the first operators to deploy WiMAX in the country. They have since deployed over 5,000 sectors and acquired over 60,000 retail and enterprise customers. Tata aims to provide high-speed broadband to residential and SMB customers using its extensive telecom infrastructure assets, including a global Tier 1 internet backbone and 40,000 km of domestic fiber. However, first mile deployment challenges around cost, municipal clearances and time remain barriers in India.

7. India – Huge Internet Potential…
• Poor infrastructure & support
• No LLU
• Legacy network with long loop lengths
• Unorganized cable infrastructure with poor network
• 2G + services in the country
Current • High Buried Access Costs
Impediments • Very low wire line penetration
• 200 months of ARPU as Capex
for growth
• Limited green-field deployment
• Limited spectrum for BWA
• Limited content offering – restricted utility for access
• Far superior roll-out mechanism with the advantage of existing infrastructure
of wireless telecom players
Wireless to be
• Spectrum auction likely in near term – Transforming the Indian industry
the technology • Potentially large coverage and faster expansion
for choice
Wireless is the best technology to drive internet growth in India

9. Auction is
WiMAX – FIRST OFF THE BLOCKS expected
Dec, 2009
3G Policy is announced
 Spectrum to be auctioned to 3-4 players
 Greater impact on voice economics rather than data services
BWA Policy is announced
 Spectrum - Auction is on the Card
Two block of 20 MHz in 2.5 GHz band and similar number in 2.3 GHz band. Total 4 blocks – 4
Operators
 Bidding would be on service area wise basis. Each bidder can get a block of 20 MHz in 2.3
GHz or 2.5 GHz bands in a telecom service area
WiMAX – Available now
 ISPs using 3.3GHz spectrum for WiMAX roll-out
 At least 3 networks being built in large towns 20 mn subs
 Good spectral efficiencies projected by 2010
 Already a 4G technology – OFDMA today
 Cost of CPE becomes indirect
Promising technology option - need catalyst to fuel the deployment

19. WiMAX Case Study: Bangalore – Some Key Facts
India's 5th largest city and the fastest growing
city in Asia.
Silicon Valley of India
Delhi
8 Mn people and over 10,000 industries
86% literacy ( national avg – at 61%)
Kolkata
Mumbai
More than 1000 software companies
Hyderabad
The population of the IT industry folks in
Bangalore Bangalore is 5% i.e 400,000.
Chennai
Higher per capita income
The city is the third-largest hub for HNIs
Biotechnology is a rapidly expanding field in
the city. Bangalore accounts for 47% of
SAFE
biotechnology companies in India.

20. Bangalore Case Study for WiMAX Roll out: Coverage & Services
Launched with 150 BTS in Dec 2007, currently at ~approx. 200 BTS
 All sites shared with TTSL – (Tata CDMA mobile Operator with 26.33 Million as in
Oct 08).
 Backhaul on predominantly fiber
 3.3 Ghz, 12 Mhz, 3 Mhz/sector, 4 sectors
 85% of the city covered
 Outdoor SS – truck roll required
 Introduced 3rd party SS to work with the BTS
 Arguably the first network in Wimax 16d to have fully interoperable 3rd party
SS
 SS installed at between 3 to 12 mtrs height, typically
 Over 12,000 customers installed in first 5 months & ~35,000 currently.
19

21. Design Assumptions
•Cell edge – QPSK
Bangalore – Complete coverage •Building edge coverage
•SS height 3 m to 12 m
•85% Probability of service by
area
•Area of coverage approx 300
Sq Km
16 QAM

22. Bangalore Case Study -Product Customization, Retail
 2 Mbps is the standard speed for volume-based plans in India –
which are the highest selling plans. However, considering the speeds
and the number of customers expected per BTS sector – customer
offering tweaked to ensure higher % of 256 Kbps sales. Go Unlimited!
% of
Speed
Customers
2 Mbps 5%
1 Mbps 1%
512 kbps 7%
384 kbps 1%
256 kbps 86%
While traditionally, WiMax users are on DHCP to enable them to pick
up the strongest signal rather than tying them to a BTS, the need of a
Static IP for a SMB customer in effect, locks the SMB to a BTS.
