Atheros Communications, Inc. (NASDAQ: ATHR), is showcasing its global leadership with innovative wireless technologies at Mobile World Congress, held Feb. 14-18, 2011 in Barcelona, Spain. As consumers demand better connectivity in all types of devices, Atheros continues to redefine the wireless experience with superior performance, simplicity and features for today's mobile lifestyle. It offers a broad portfolio of standalone and combination (both monolithic and multi-chip) products that provide best-in-class Wi-Fi®, Bluetooth® and GPS technologies for a wide range of cellular phones, tablets, media players, gaming devices, notebooks, netbooks and other portable CE products.

In addition to showing a variety of commercially-available products that feature its mobile connectivity solutions, Atheros will demonstrate many emerging technologies and applications that will appear in the next generation of connected devices. All demonstrations will take place in Atheros' private suite, located in Hall 1 of the Fira de Barcelona (stand 1G39).

Atheros' product and technology demonstrations include:

• ROCm® Mobile Wi-Fi solutions -- Atheros is pushing the boundaries of wireless performance to enable advanced media applications in even the smallest devices. It will demonstrate the unique dual-band 802.11n capabilities of its Align® 1-stream mobile Wi-Fi solutions, which leverage 40 MHz transmissions in the 5 GHz band to deliver up to 85 Mbps of bandwidth for video streaming, fast sync-and-go, and Web browsing.
• Wi-Fi / Bluetooth combinations -- Atheros will showcase its new AR6233 system-in-package (SIP) for computing, tablets and portable CE devices (such as handheld games and eReaders). The combo solution provides manufacturers with greater design flexibility, while ensuring enhanced wireless performance, coexistence and battery life for consumers.
