Leading Wi-Fi® Chipmakers Verify Interoperability of Draft-N Solutions

Atheros and Broadcom to Demonstrate IEEE 802.11n Draft Specification Compatibility at COMPUTEX

SANTA CLARA and IRVINE, Calif., May 31, 2006 — Atheros Communications, Inc. (NASDAQ: ATHR) and Broadcom Corporation (NASDAQ: BRCM) today announced interoperability between their draft 802.11n solutions. During the last month, the companies have jointly conducted interoperability testing between Atheros’ XSPAN® and Broadcom® Intensi-fi™ chipsets. Tests have verified that the wireless LAN (WLAN) solutions work together at throughput speeds greater than 100 Megabits-per-second (Mbps), using mandatory modes of the IEEE 802.11n specification (draft 1.0).

Cross-vendor interoperability testing demonstrates the commitment of Wi-Fi® technology leaders to meet growing consumer demand for high-performance products that work seamlessly together. As 802.11n technology further expands beyond PCs and networking gear, into mobile and entertainment devices, interoperability allows consumers to choose a variety of products and brands without worrying about compatibility issues.

This is the first in what is expected to be a series of interoperability tests conducted with leading wireless companies to broaden the scope of interoperable systems. Over the coming months, the testing will lay the groundwork for successful Wi-Fi Alliance testing when the organization’s certification process is finalized.

“The excellent performance demonstrated between Atheros and Broadcom devices shows that the 802.11n draft, when adhered to and properly implemented, supports multi-vendor interoperability,” said Bill McFarland, chief technology officer of Atheros. “As the market moves toward these interoperable 802.11n draft chipsets, consumers will be able to purchase a wide range of networking gear from numerous vendors that interoperate at unprecedented speeds.”

“Multi-vendor interoperability is the clear goal for next generation Wi-Fi because it alleviates the incompatibility and limited selection of products that plague users of proprietary products,” said Bill Bunch, director of 802.11n product management for Broadcom’s Home and Wireless Business Unit. “The progress towards interoperability is a strong validation that the draft 802.11n specification will deliver the benefits of a high-performance wireless ecosystem built on industry standards.”

Atheros and Broadcom will be demonstrating draft 802.11n product interoperability at the COMPUTEX Conference in Taipei, Taiwan on June 6-10, 2006.
