Rich Redelfs Appointed Vice Chairman of the Board

“Rich helped build a tremendous executive team and did an excellent job piloting the company from an innovative start-up to a market leader in a very short period of time,” said John Hennessy, chairman of the board of directors for Atheros. “We are very excited about Craig’s appointment as president and CEO. His deep understanding of wireless systems and his strong track record of operational excellence make him the perfect choice to extend Atheros’ technology leadership position in the WLAN market and help the company move into new application areas that will enhance its future business growth.”

Barratt has been heavily involved in business, technology and application development for Atheros, and in his new role will help the company extend its leadership position in WLAN products for the enterprise and home, diversify its customer base, and further expand into new markets such as consumer electronics. Barratt will build upon Redelfs’ accomplishments, which saw Atheros deliver the world’s first 802.11a chipsets and the multi-mode (802.11a/b and a/g/b) WLAN chipsets now favored by four of the world’s top five PC manufacturers.

“Atheros dominates the multi-mode WLAN market and is a leading provider of 802.11g draft standard solutions,” said Dr. Barratt. “I aim to leverage our technology and performance edge to expand our position in existing and emerging markets. The marketplace is rapidly transitioning to higher performance and multi-mode products, which will continue to drive our growth."

Barratt’s transition to CEO is effective immediately. Prior to his role as vice president of technology for Atheros, Barratt served as executive vice president and general manager at ArrayComm Inc., a wireless technology company that has deployed its technology in over 100,000 wireless base stations. Barratt holds a doctorate in electrical engineering from Stanford University
