Future internet economy oecd policy brief june 2008 l.jpg
Future Internet EconomyOECD 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 AffordableInternet AccessWherever*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.

Why do we need 2mbps broadband l.jpg
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


Mobile voice vs mobile internet l.jpg

>100x higher

data rate

requirements

1-5 Mbps bursty traffic

10 Kbps constant rate

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


Mobile internet service concept l.jpg
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

Intel’s smallest processor built with the world’s smallest transistors

Highest Performance in its class

Ground-up Design for CPU & Chipset

Intel’s 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 MobileMark’05 Office Productivity suite on Microsoft* Windows* XP for a period of 90min at 50°C .

  • Idle power is measured when running Windows Vista in idle at 50C

Ofdma mimo key enablers of mobile broadband internet l.jpg
OFDMA + MIMO:Key Enablers of Mobile Broadband Internet

OFDMA

  • Wider band of spectrum

  • 1000’s of carrier, sub-carriers

  • Flexible allocation of resources

S1

S2

S3

MIMO

  • Multiple paths

  • Narrowband processing

No more debates on modulation

& multiple access

MME/UPE

WiMAX or LTE = Same Level of Upgrade

2G, 3G Network (GSM, EV-DO, HSPA)

2G, 3G Core Network

Upgrade core network to support more IP data traffic

New data overlay network

4G Network:

(WiMAX or LTE)

All IP Core

Radio Access Network (RAN):

> 90-95% of new CapEx*

Core Network Equipment

< 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 operator’s existing network.

* 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

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*

Ieee 802 16m backward compatibility l.jpg
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 (b=c)

  • .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 (b=d)

  • .16m able to disable legacy support for e

WiMAX Release 2.0 (16m) will be tightly

backward compatible to release 1.0 (16e)

Summary l.jpg
Summary

Internet is a major driver of economic growth globally; mobile Internet is essential in accelerating this growth

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

Mobile Internet requires a revolution in technology and business case; NOT an evolution of legacy networks and services

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.
