Atheros Enables Industry-Leading Wi-Fi in Next-Generation Cable Modem Gateways Based on TI Puma 5 Product Family

Comprehensive Suite of Platform Solutions Leveraging DOCSIS 3.0 and 802.11n Technologies Unleashes the Full Potential of the Connected Home Network

THE CABLE SHOW 2008, NEW ORLEANS, May 19, 2008 — Atheros Communications, Inc. (NASDAQ: ATHR), a leading developer of advanced semiconductor system solutions for wireless and wired communications, announced that its high-performance XSPAN® 802.11n single and dual-band options, and its popular 802.11g solutions now support Texas Instruments’ (TI) next-generation, wireless-enabled cable modem gateway platform. The new reference designs are the first in a series based on Atheros’ Wi-Fi and TI’s Puma 5 family of DOCSIS® 3.0 cable modem chipsets, which are optimized for triple play and next-generation IP services. The collaboration between Atheros and TI enables Multiple Service Operators (MSOs) or service providers to easily add Wi-Fi connectivity to cable modem gateways, eliminating the need for multiple boxes, and simplifying home and SOHO networks. MSOs can now choose among a wide array of Atheros high-performance Wi-Fi options to generate incremental revenue from subscribers enabled with wireless services.

Atheros WLAN together with TI’s Puma 5 family offers a uniquely architected, state-of-the-art platform which meets the demanding performance and feature requirements of the cable modem gateway market. This complete solution provides OEMs with a full hardware development kit (HDK) and software development kit (SDK), enabling them to easily and quickly customize the fundamental design with value-added features and achieve significant time-to-market advantages. Additionally, the joint platform provides a single source to OEMs for design support on both cable modem and WLAN technologies.

Atheros’ XSPAN system-on-chip solutions provide a rich set of features to the Puma 5 platform including an integrated, high-performance, wireless network processor (WNPU) 400 MHz subsystem which gives significant offload capabilities to the cable modem’s host CPU resulting in higher throughput. The XSPAN family features an innovative triple-radio MIMO design, which delivers industry-leading whole home coverage.

“Integrating Wi-Fi with DOCSIS 3.0 cable modems enabled by TI’s Puma 5 family of products gives MSOs even more reach into the home network, allowing them to provide value-added features including remote configuration, assisted troubleshooting and more,” said Ran Senderovitz, TI's cable business manager. “Building Atheros’ WLAN technology on top of TI’s Puma 5 packet processor-based DOCSIS 3.0 cable modem products gives our customers the flexibility to create differentiated gateway solutions to meet their market needs.”

“Atheros’ experience with service providers is unmatched in the carrier market. Our wireless LAN solutions are featured in broadband home gateways worldwide, as well the entire ecosystem of Wi-Fi products including leading PCs, retail networking equipment and mobile consumer devices,” said Mike Stauffer, director of marketing, broadband carrier networking for Atheros. “This collaboration with TI, a leader in the cable modem chip market, provides customers with a comprehensive portfolio of single-source, wireless cable modem gateway solutions that will enable MSOs to compete more effectively and enhance revenues.”

For MSOs who want to offer high-performance and cost-effective wireless connectivity, Atheros satisfies their needs with the industry’s most-integrated 802.11n and 802.11g solutions. Atheros’ XSPAN 11n AR9001AP and 802.11g AR5007AP designs feature the industry’s highest integration of WLAN baseband/MAC, multiple radios, WNPU, and Ethernet to enable the most complete, cost-efficient wireless home gateways. The company’s unmatched silicon integration and board design expertise result in mature solutions that substantially lower RBOM component count versus competitive designs.

Atheros solutions for wireless cable modem gateways provide MSOs with advanced carrier-class features to deliver an enhanced user experience and the ability to increase subscriber revenue and profitability. In addition, they support the Linux® operating system and comply with industry standards WMM® (Wi-Fi Multimedia™) and Wi-Fi Protected Setup™ with Atheros’ JumpStart for Wireless™, the company’s simple network configuration software. All of Atheros’802.11n and 802.11g solutions support the WPA™, WPA2™ and 802.11i standard and feature a hardware-based advanced encryption engine to ensure secure connectivity.
