Technology Overview

Qualcomm offers the industry's most innovative and complete

portfolio of 802.11n wireless LAN chip solutions. This generation of

Qualcomm’s 802.11n technology builds upon the company’s Wi-Fi

leadership – with enhanced performance, higher integration, smaller

form factors and lower overall cost – to meet the needs of the rapidly

growing 802.11n market. Like all Qualcomm’s 11n solutions, the new

fourth-generation solutions are compliant to the IEEE 802.11n

specification.

Qualcomm fourth-generation Wi-Fi solutions feature:

£ Leading Integration that delivers end-product cost and form

factors to drive broad market adoption of 802.11n products

£ Single- and Dual-Band, and Multiple MIMO Configurations that

enable OEMs to balance product price/performance for specific

applications and market segment requirements

£ Rich Media and Peripheral Interfaces that anticipate the

requirements for advanced media networking applications

and allow end-product feature differentiation

£ Easy Network Setup with the industry’s simple network

configuration software that supports both the PIN and

push-button setup methods

Product Overview

Introducing the AR9280, the single-chip, dual-band (2.4/5 GHz)

solution for PCIe in Qualcomm’s third generation of products. The

AR9280 is the most integrated, most compact 802.11n solution

for dual-band PCIe on the market, featuring a Half-Mini Card form

factor that is 30% smaller than the nearest competitive 11n. This

breakthrough product will drive the transition of legacy Wi-Fi to

802.11n in the mainstream-priced PC market. It offers the optimal

balance of performance, power and price with its dual-band, 2x2

MIMO configuration which features downshift to 1x1 MIMO with

Dynamic MIMO Power Save.

With this dual-band design, consumers will enjoy universal

connectivity to any 802.11 network, including legacy 802.11b/g and

802.11a/g. While the 2.4 GHz band readily performs less demanding

data applications, the virtually interference-free 5 GHz band supports

high-bandwidth, latency-sensitive applications like HD-quality video

streams and wireless VoIP. Qualcomm is the leading provider of

high-performance, dual-band WLAN solutions in the retail, PC OEM,

enterprise and metro Wi-Fi segments worldwide.

In addition, the AR9280 follows Qualcomm’s drive toward integration

as the company's eighth, single-chip, client solution on the market.

The result is a superior package footprint that drives down cost

and enhances design flexibility.
