Atheros XSPAN® Technology
Atheros offers the industrys most innovative and complete portfolio of 802.11n wireless LAN chip solutions. This generation of Atheros’ XSPAN 802.11n technology builds upon the company’s XSPAN 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 Atheros 11n solutions, the new fourth generation solutions are compliant to the IEEE 802.11n specification.

Atheros fourth-generation XSPAN chips 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 & 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 XSPANs 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.
