Market OpportunitySignificant un-served market needs Market opportunities for a

cost-effective wireless broadband solution.

Developing & Underserved Markets Lacking Communication Infrastructure

DSL and Cable ModemReplacement and Extension

Wireless Backhaul in Cellular and Wi-Fi Networks

Portable and Mobile Broadband Coverage

Support of Rich-Data Services, Straining Current Networks

In all such scenarios, an effective broadband

wireless offering based upon an open standard

can meet the market need with favorable economics


Standards

The WiMAX label was introduced by the WiMAX Forum to promote the 802.16 family of standards

The early iterations of 802.16 focused on line-of-sight (LOS) applications using high frequency bands between 10-66 GHz

802.16(2001)

802.16c(2002)

802.16a(2003)

802.16d(Oct 2004)

802.16e(Dec 2005 est.)

Recent efforts have focused on non-line-of-sight (NLOS) applications between 2-11 GHz

§ 802.16d (published as 802.16-2004) Fixed & Nomadic

§ 802.16e (to be published as 802.16-2005) Fixed, Nomadic, Portable, and Mobile

IEEE 802.16 is the standard. WiMAX is the name.

WiMAX Forum specifies profiles for 802.16-2004 and 802.16e802.16-2004 and 802.16e are broadly defined by IEEE with many implementation options

A profile is a narrowly defined subset of the IEEE technology specifications

By conforming to the WiMAX profile a vendor benefits by…§ Receiving certification from an

independent testing lab

§ Ensuring interoperability with certified products from other vendors

WiMAX 802.16 Rev. E meets the market demand for cost-effective and high-performing broadband wireless service

802.16 Rev. E will deliver…

802.16 Rev. D and 802.16 Rev. E

represent different and incompatible

technologies

802.16 Rev. E will become the dominant WiMAX standard even

for fixed systems

Lower Cost§ Volume deployments lead to

economies of scale

§ Commitment from major chipset manufacturers

Better Performance§ Enhanced Physical Layer

§ High-performing coding schemes

§ Advanced antenna techniques§ Power reduction

Path to Mobility§ Future-proof solution

§ Ubiquitous broadband will be a key differentiator

What is FDM

Frequency Division Multiplexing (FDM )

Uses multiple frequencies to simultaneously transmit multiple signals in parallel. Each signal has its own frequency range (sub carrier) which is then modulated by data

OFDMA


OFDMA-The Multi User Access

OFDMA allows some sub-carriers to be assigned to different users. For example, sub-carriers 1, 3 and 7 can be assigned to user 1 and sub-carriers 2, 5 and 9 to user 2.

Challenges for Indian Market

1) Spectrum Allocation 2) CPE Prices


Challenge 2 – CPE PricesThe estimates given below were given by WiMAX Forum but please note that the CPE pricing has come down drastically and even more than the Forums expectation due to the increased competition and acceptability of WiMAX worldwide.

The actual Pricing today are as follows SME Outdoor CPE : $150 -180 Residential Outdoor Terminal : $ 100 -120

Residential Indoor Terminal : < $ 100


Way to Success – Solution for Challenges

Spectrum Allocation

• Government encouraging WiMAX for India especially rural areas

• Department of Space asked to vacate frequency band from 2.5 GHz band

• 2.3 GHz and 5.8 GHz bands also considered for BWA

CPE Prices

• The CPE price are expected to be below $100 by 2011

• Computer original equipment manufacturers are set to roll out WiMax-enabled desktops and laptops in India during 2008 ,just like popular Wi-Fienabled Laptops
