Why WiMAX (Worldwide Interoperability for Microwave Access) ?

Operators need service differentiation to compete Advantage Greenfield operators Wire line replacement with Wireless

PSTN-quality voice and DSL-like dataProfitable with mass-market consumer ARPUSolution for rural coverage

(WiMax) – A Standard & Not the Technology

WiMAX defined by the WiMAX Forum, formed in June 2001 to promote conformance and interoperability of the IEEE 802.16 standard, officially known as “Wireless MAN”

The Forum describes WiMAX as "a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL".

WiMAX is not a technology, but rather a certification mark, or 'stamp of approval' given to equipment that meets certain conformity and interoperability tests for the IEEE 802.16 family of standards.

Neither WiMAX, nor Wi-Fi is a technology but their names have been adopted in popular usage to denote the technologies behind them. This is likely due to the difficulty of using terms like 'IEEE 802.16' in common speech and writing.

Benefits of a Standard For Equipment and Component Standardization creates a volume

opportunity Vendors  fosters rapid innovation and the addition of new components and  services. Concentrate on specialization (i.e. Base Stations or CPEs) - no longer need to create an

entire end-to- end solution as in proprietary model Standardization creates a volume opportunity

For Consumers  Receive services in areas that were previously out of the broadband loop More players in the market translate into more choices Quick “trickle down” effect of cost savings to consumers, translating into lower monthly rates

For Service Providers Common Platform drives down costs, fosters healthy competition and encourages innovation Enables a relatively low initial CAPEX investment and incremental expenditures that reflect

growth No more commitments to a single vendor, a typical by-product of the proprietary technology

model Wireless systems significantly reduce operator investment risk

WiMAX Standards

IEEE Standards 802.16-2001, 802.16c-2002, and 802.16a-2003. Original WiMAX standard (IEEE 802.16) specified for the 10 to 66

GHz range 802.16a updated in 2004 to 802.16-2004 (also known as 802.16d), added

specification for the 2 to 11 GHz range. 802.16d (also known as "fixed WiMAX") was updated to 802.16e in

2005 (known as "mobile WiMAX"). and uses scalable orthogonal frequency-division multiplexing (OFDM) as opposed to the OFDM version with 256 sub-carriers used in 802.16d.

More advanced versions including 802.16e also bring Multiple Antenna Support through Multiple-input multiple-output communications

QoS & Security

• OFDM & Dynamic Bandwidth Allocation • WiMAX coding and modulation schemes ensure steady signal

strength over distance by decreasing throughput over range to deliver the best QoS possible

• Prioritizing traffic• WiMAX offers state of the art security via authentication and

strong encryption• WiMAX (802.16-2004) uses X.509 certificates for authentication

and 56-bit Digital Encryption System (DES) for encryption of the data stream. Mobile WiMAX (802.16e-2005) uses EAP for authentication and Advanced Encryption System for encryption
