Reference designs meet dual-band specs
PC card and AP reference designs based on the innovative Prism Duette chipset have passed all interoperability testing and have received Wi-Fi 802.11a, b and g certification from the Wi-Fi Alliance.
Award for dual-band chipset
Semiconductor Insights (SI) has presented Intersil with its 2003 Insight Award for most innovative wireless device for the Prism Duette dual band, 802.11 a, b and g chipset.
"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 and 5GHz 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 and 5GHz WLAN devices.
Because it is 100% 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 2.4 and 5GHz 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 5GHz 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 2.4GHz 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 multimode WLAN solutions for portable devices that will provide seamless roaming capabilities anywhere in the world regardless of the infrastructure", commented Larry Ciaccia.
