--PRISM Duette delivers seamless compatibility for WLANs operating
      in both 2.4 GHz and 5 GHz bands
    --Intersil will sample PRISM Duette by year's end and targets
      product to be on the market early in 2003

"Our goal for PRISM WLAN technology has always been to ensure that 2.4 and 5 GHz WLANs are complementary technologies that offer complete flexibility in developing and deploying WLAN platforms," said Larry Ciaccia, vice president and general manager for Intersil's Wireless Products Group. "We've leveraged over five years of WLAN innovation and IC integration in creating PRISM Duette. Our unique two-chip solution will enable seamless mobility between 2.4 GHz and 5 GHz WLANs and provides a compelling solution for our customers."

PRISM Duette features Intersil's highly integrated Baseband Processor and Medium Access Controller (BBP/MAC) and direct down conversion (ZIF) architecture. Its dual-band OFDM-based (Orthogonal Frequency Division Multiplexing) technology communicates with both 2.4 GHz and 5 GHz WLAN devices. Because it is 100 percent standards based, PRISM Duette is an ideal technology to design into leading edge wireless networking platforms, while offering owners of existing wireless networks investment protection as they migrate towards next-generation WLAN technology.

PRISM Duette enables a wide range of broadband WLAN applications leveraging PRISM(R) 2.4 GHz and 5 GHz technologies to support infrastructure applications such as building-to-building wireless bridging, environments where a very high density of users require the extra channel capacity available in the 5 GHz band and bandwidth hungry applications such as video conferencing. PRISM Duette is also ideal for home networking applications such as simultaneous multi-channel streaming video and voice and CD-quality audio playback. The device also uses the 2.4 GHz band to support legacy Wi-Fi equipment performing 802.11b WLAN applications including Internet access, Web browsing and messaging.

"We're committed to providing our customers with complete 802.11a, b, g, dual-band and multi-mode WLAN solutions for portable devices that will provide seamless roaming capabilities anywhere in the world regardless of the infrastructure," commented Larry Ciaccia.
