Atheros Brings Wireless Connectivity to Next-Generation Entertainment-Rich Smartphones

Atheros ROCm Technology Provides High-Performance WLAN for NVIDIA APX 2500 Development Platform Debuting at Mobile World Congress 2008

MOBILE WORLD CONGRESS 2008, BARCELONA, Spain, Feb. 11, 2008 — Atheros Communications, Inc. (NASDAQ: ATHR), a leading developer of advanced wireless and wired solutions, is demonstrating its Radio-on-Chip for Mobile (ROCm®) family of wireless technologies, including its industry-leading mobile WLAN solutions, its Bluetooth for PCs and Headsets, and its new GPS product portfolio at Mobile World Congress 2008 this week. The ROCm family features high-performance, low-power wireless connectivity to deliver the most satisfying end-user experience with an array of wireless technologies. Atheros will demonstrate its entire ROCm portfolio and feature its AR6001 mobile WLAN implementation on the NVIDIA APX 2500 development platform, a breakthrough applications processor designed to enable advanced multimedia features in a new breed of smartphones, at Mobile World Congress 2008 in the Atheros booth (Stand 2.1F78, Hall 2-1).

Next-generation smartphones are rapidly evolving into personal multimedia computers that require extraordinary WLAN performance and power efficiencies. To support this new era of mobile computing performance, Atheros’ ROCm solutions deliver infrastructure-class throughput while using 70 percent less power in active mode than competing Wi-Fi products, and near-zero (.06mW) power in standby mode.

“To deliver advanced multimedia content and the latest Web 2.0 applications in WLAN environments, we have integrated the Atheros AR6001 chip into our APX 2500 development platform,” said Michael Rayfield, general manager of the mobile business at NVIDIA. “Next-generation smartphones will require fast, reliable wireless connectivity to deliver engaging content to multimedia-hungry consumers on-the-go, and Atheros will help to deliver this experience.”

The AR6000 family of mobile WLAN solutions consisting of 802.11g and 802.11a/g single chip options, deliver Atheros-class Wi-Fi performance for optimal range and throughput. This enables smartphone manufacturers to provide high-speed connections to any of the growing number of Wi-Fi networks in hotspots, homes and enterprises.

“Next-generation smartphones will enable entertainment-rich applications that Atheros’ ROCm solutions for mobile WLAN were designed to support,” said Sam Endy, vice president and general manager of the mobile wireless business unit for Atheros. “Our ROCm family features the industry’s lowest power consumption along with the highest throughput for mobile WLAN, extending battery life and increasing the number of downloads and amount of talk time between charges in a new class of mobile devices.”

The integration of Atheros’ AR6000 solutions into the APX 2500 platform allows mobile phone designers to leverage a complete, turnkey design that enables the fastest time-to-market for cutting edge multimedia smartphones. Atheros ROCm designs provide full driver support for Microsoft’s® Windows® Embedded CE 6.0. Along with support for Linux®-based solutions, Atheros’ mobile WLAN technology offers significant market advantages to accelerate design cycles.
