Future Internet Economy OECD Policy Brief, June
2008

• The Internet now underpins a range of new
  economic activities as well as activities and
  infrastructures that support our economies, from
  financial markets and health services to energy
  and transport.

In the longer term, small wireless sensor
devices embedded in objects, equipment and
facilities are likely to be integrated with the
Internet through wireless networks that will
enable interconnectivity anywhere and at
anytime.

Vision for Mobile Internet
Transparent Affordable Internet Access Wherever
You Are
Wi-Fi Mobile WiMAX 1st generation Mobile
Internet
WiMAX connectivity requires a WiMAX enabled
device and subscription to a WiMAX broadband
service. Availability of WiMAX is limited, check
with your carrier for details on availability.

What is the killer application?
The Internet!
5
Ingredients for Mobile Internet Success
Affordable flat-rate charge
Ubiquitous Connectivity
Low-cost/Low Power PCs
True Internet not Mini-Internets
Simple Roaming
Device Retail Model
Open and PC-like Mobile Devices
low cost modems

Why do we need 2Mbps broadband?

• Internet is getting more complex with rich with
  multi-media
• Web pages getting more complex
• Avg web page size has tripled in past 5 years
• 75 HTTP requests from images, up from 20 in
  03
• 90 of web pages have images today
• Video and HD are here
• Average file size on the web 10 MBytes
• Video accounts for 99 of all bytes transferred
• And they are growing in size and length 90 of
  videos are 3min, up from under 1 min in 97
• Quality is degrading
• The more bandwidth, the more people benefit from
  the web

Mobile Internet requires a Per-User Multi-Mbps
Connection
7
Mobile Voice vs. Mobile Internet

• A network optimized for mobile voice cannot
  handle high numbers of mobile Internet users
• More spectrum needed for acceptable service level
  
• More backhaul different network architecture
  required

Mobile Internet requires a technology revolution
8
Mobile Internet Service Concept

• Typical ARPU for 10 Kbps mobile voice service is
  50/month in the U.S./10/month in India
• Internet requires a 1-5 Mbps class of service and
  an monthly rate of less than 30/month in the
  U.S. / 10/month in India
• ? Need to provide 100-500x the service level at
  1/2 the cost in the U.S. the same cost in
  India!!!!

Mobile internet requires a business model
revolution

Intel Atom Processor
Intels smallest processor built with the worlds
smallest transistors
Highest Performance in its class
Ground-up Design for CPU Chipset
Intels lowest power CPU
ATOM will revolutionize the PC industry to mass
market affordability and mobility

• HT Technology can add 200mW of power above quoted
  TDP for HT SKUs when multi-threaded applications
  are run.
• Average power is defined as measured CPU power
  whilst running BAPCo MobileMark05 Office
  Productivity suite on Microsoft Windows XP for
  a period of 90min at 50C .
• Idle power is measured when running Windows Vista
  in idle at 50C

OFDMA MIMOKey Enablers of Mobile Broadband
Internet
OFDMA

• Wider band of spectrum
• 1000s of carrier, sub-carriers
• Flexible allocation of resources

S1
S2
S3
MIMO

• Multiple paths
• Narrowband processing

No more debates on modulation multiple access

4G Network (WiMAX or LTE)
All IP Core
Radio Access Network (RAN) gt 90-95 of new CapEx
Core Network Equipment lt 10 of new CapEx
Both WiMAX LTE require new RAN equipment
devices. Neither is backward compatible to
3G. Both can interwork well with existing 2G, 3G
networks.
Intel estimates. Percentage varies based upon
the operators existing network.

Mobile WiMAX 2.0 (802.16m)300 Mbps (2010/2011)

• Peak sector throughput over 300 Mbps DL (in 20
  MHz)
• TDD FDD support
• Multi-carrier support BW of up to 100 MHz
• Increased VoIP capacity
• Even lower link access latencies
• Enhanced coverage
• Enhanced multi-radio coexistence and
  inter-technology handover
• Integrated multi-hop relay
• Self-organizing base stations
• Increased mobility Up to 350 km/hr

19
Note Actual mobility throughput depends on
environmental conditions and Service Provider
provisioning. Aggregate peak sector throughput
calculated using 20 MHz for DL. FDD support in
2010

IEEE 802.16m Backward Compatibility

• 802.16e/802.16m Mixed
• Operate on the same RF carrier with
  same/different BW (a)
• Support a mix of 16e 16m MS on same RF carrier
  (c and e)
• .16e MS same performance as16e BS (bc)
• .16m BS support handover of .16e MS to/from.16e
  BS (b ? ? c)
• .16m MS operate with .16e BS with same
  performance as.16e MS (bd)

• .16m able to disable legacy support for e

WiMAX Release 2.0 (16m) will be tightly backward
compatible to release 1.0 (16e)

Summary
Internet is a major driver of economic growth
globally mobile Internet is essential in
accelerating this growth
Mobile Internet requires a revolution in
technology and business case NOT an evolution of
legacy networks and services

• Mobile WiMAX is the first generation OFDMA/MIMO
  based cellular mobile radio technology - its
  here today leading the mobile internet revolution

OFDMA/MIMO is the radio access technology for
Mobile WiMAX and next generation mobile internet
technologies
Mobile WiMAX has a backward compatible
technology roadmap with IEEE 802.16m specified to
meet the requirements of mobile internet in 2011
India is in a special position to adopt Mobile
WiMAX (4G) today and lead the mobile internet
revolution.
