Airgo Networks, a secretive Silicon Valley start-up composed of a superteam of wireless pioneers, on Monday said it will reveal plans for what analysts say could offer a revolution in wireless transmission quality. It will begin offering sample versions of its short-range radio antenna chips to equipment makers that promise to boost the speed, range and reliability of wireless devices indoors and between nearby buildings.

The 150-employee company includes the former Philips team that designed Apple Computer Inc.'s Airport wireless radio, the first mainstream wireless LAN product, and Intel's Centrino Wi-Fi chipset. Big name venture capitalists, including Nokia's venture arm, back it.
