SUNNYVALE, Calif., October 23, 2000 - Mark Bercow has joined Atheros Communications as vice president of Marketing, it was announced today by Rich Redelfs, president and CEO of the two-year-old firm whose "Radio-on-a-Chip" technology aims to provide wireless networking technologies for the office and the home.

Mr. Bercow's responsibilities include overseeing the company's strategic marketing direction, product definition, business development, positioning, messaging and marketing communications. He reports to Mr. Redelfs.

Most recently, Mr. Bercow was vice president of Strategic Alliances and Platform Development for Palm, Inc. He was responsible for the Palm OS platform, as well as "The Palm Economy" whereby Palm's licensees, strategic partners, and third-party developers help the platform gain leadership in the market. During his more than three years with Palm, Mr. Bercow was responsible for enlisting more than a dozen licensees, dozens of strategic alliances, and over 100,000 registered third-party hardware and software developers. This co-dependent ecosystem between Palm and its partners has made the Palm OS the leading handheld computing platform around the world.

"We are absolutely delighted to have Mark join us," said Mr. Redelfs. "Our breakthrough in wireless is much like the breakthrough that Palm provided to the handheld market. Both are enabling technologies that will be used in a broad variety of business and consumer applications. Mark's success at Palm makes him the ideal person to lead our marketing efforts to create and drive a whole new wireless ecosystem."

"Atheros represents to me an amazing convergence of breakthrough technology, a stellar gathering of some of the brightest wireless technologists in the world, and a market that is ready to explode globally," said Mr. Bercow.
