rDriving the Wireless Broadband Revolution

Market is converging onto the IEEE 802 standards WiMAX extends the coverage of Wi-Fi 3G best suited to high mobility/low data rate applications

The IEEE 802.16 specifications

802.16 – core specification

10-66 GHz systems

802.16a – ratified in January 2003

Systems using 11 GHz and below

ETSI has ratified HiperMAN with identical MAC “global specification”

802.16 rev. d – to be called “802.16-2004”

Incorporates 802.16a and conformance profiles/procedures from WiMAX Forum

802.16e – nomadic roaming (est. ratification in 2005)

Defines hand-off of nomadic Subscriber Station from one Base Station to another

Don’t get caught up in specification alphabet soupWiMAX Forum Certified™ sets the standard

New Intel/Proxim Collaboration

Intel and Proxim are collaborating to develop, deliver fixed and portable WiMAX solutions

Proxim WiMAX systems to utilize Intel silicon 802.16 revD base station

Reference design: subscriber units to accelerate time-to-market

Co-development of 802.16e base station

Collaboration on standardization efforts: 802.16e

Key partnership to drive seamless mobility via WiMAX Forum Certified: Wireless infrastructure, client (SmartPhones, PDAs) support

Co-marketing efforts
