The Atheros AR9280 dual-band (2.4GHz and 5GHz) 2×2 MIMO and AR9281 single-band (2.4GHz) 1×2 MIMO PCI Express(TM) (PCIe) designs integrate the radio, baseband/MAC and host PCIe interface into the industry's smallest 802.11n footprint. Reference designs are available for both PCIe half-Mini Card and full-Mini Card form factors. The AR9280 and AR9281 provide industry-leading power savings and 11n rate over range performance, supporting up to 300 Mbps physical data rates and more than 200 Mbps of real user throughput.

"Atheros is pleased to participate with AMD as part of the Better by Design program for its next-generation AMD notebook platform," said Todd Antes, vice president, Wireless Networking & Computing, of Atheros. "Our XSPAN solutions deliver the best wireless experience, leveraging validated 11n performance with industry-leading power efficiency."

Atheros' AR9280 and AR9281 are specifically designed to enable advanced PC platforms with superior power efficiency to significantly extend battery life. Several innovative system-level power-savings protocols, algorithms and circuit design techniques including Dynamic MIMO Power Save (DMPS), Unscheduled Automatic Power Save Delivery (UAPSD) and Atheros Wake-on-Wireless(R) are employed in these designs.

"We believe that notebooks today must be optimized to deliver stunning visual performance and energy efficiency for the ultimate, high-definition experience on the go," said Chris Cloran, vice president, Notebook Division, AMD. "Achieving low-power mobility across all the systems was a key design criteria of our next-generation notebook platform. Atheros XSPAN for PCs readily met our requirements with its leading 11n performance combined with extraordinary power efficiency."

The AR9280 and AR9281 also support Windows XP(R), Windows Vista(R), Mac OS(R) and Linux(R) operating systems. In addition, they include support for industry standards WMM(R) (Wi-Fi Multimedia(TM)), Wi-Fi Protected Setup(TM) via Atheros' JumpStart for Wireless(TM), the company's industry standardized simple network configuration software, and Cisco Compatible Extensions (CCX).
