Intersil’s PRISM Team Collaborates with Actiontec to Develop Embedded Mini-PCI Wireless LAN Solutions for Laptops and Information Appliances

Actiontec launches PRISM-based dual-mode WLAN/modem card, a world’s first

IRVINE, CA. November 30, 2000 — A collaboration between Intersil (NASDAQ: ISIL), the world’s leading developer of silicon technology for Wireless Local Area Networks (WLANs), and Actiontec Electronics, Inc., a leading manufacturer of broadband products, will yield new embedded solutions for built-in wireless networking connectivity in PCs, laptops and handheld information appliances for both home and office use.

Using Intersil’s PRISM® WLAN chip set, Actiontec has developed advanced WLAN products on very small mini-PCI cards that can be easily embedded in many types of portable devices including laptops, palmtops and Internet appliances.

One of the first products to result from this collaboration is the world’s first dual-mode mini-PCI card that provides two types of connectivity on one small card — phoneline V.90 modem connectivity and wireless IEEE 802.11b connectivity. The new Actiontec dual-mode mini-PCI card combines Intersil’s PRISM® WLAN technology with Actiontec’s V.90 modem technology. The new dual-mode card and a single-mode WLAN card are both optimized for high data rate embedded wireless networking applications for use in small handheld devices such as laptop PCs, Web pads and digital cameras.

"It’s quite significant that full-up IEEE 802.11b WLAN and V.90 modem capabilities can be combined on such a small card. This will ultimately deliver big benefits to users in homes and offices who will benefit from the lower costs and smaller sizes of appliances they use in work and play," said Larry Ciaccia, vice president and general manager of PRISM Wireless Products. "Actiontec’s new embedded mini-PCI solutions move this promise closer to reality and allow manufacturers to build-in wireless capability to their products, eliminating add-in cards that are more costly for the end-user plus take up precious PCMCIA card slots in laptops."

The wireless capability of the new card is made possible by Intersil’s newest PRISM chip set and WLAN adaptor design. The PRISM 2.5 design integrates the digital portion — the baseband processor (BBP) and the medium access controller (MAC) — onto a single integrated circuit, eliminating a large number of I/O pins thus reducing board complexity, size and manufacturing cost. These advancements have enabled the move to the smaller mini-PCI form factor and lead the way toward even smaller forms such as Compact Flash, Cardbus, USB and embedded modules.

"Wireless networking is one of the hottest trends in mobile computing. Actiontec is effectively addressing this trend as well as the dial-up connectivity needs of OEMs by combining 802.11 wireless networking and V.90 modem technology into one mini-PCI slot," stated Ramzi Al-Harayeri, vice president of OEM sales for Actiontec. "This revolutionary solution eliminates the need of users to sacrifice a valuable PC card slot to stay connected to their wireless LAN or to the Internet. By achieving an unprecedented level of integration, it preserves a PC Card slot for other applications while providing system manufacturers with the greatest possible flexibility in system design."

Actiontec intends to launch a complete line of wireless products that will utilize Intersil’s PRISM technology in the first quarter of 2001. Actiontec’s product offering for Tier 1 OEM customers will include two mini-PCI cards, both PRISM WLAN-based; the dual-mode, 11 Mbps WLAN and Actiontec V.90 modem card and the 11 Mbps WLAN single-mode card. Samples of the two mini-PCI products are available today, in limited quantities.

Adoption of PRISM Technology
Since introducing the PRISM WLAN chip set in 1996, over fifty companies have incorporated PRISM chips in more than 100 product designs. In a May 2000 report, Cahners In-Stat Group called Intersil "the dominant force in the WLAN chip set marketplace with their PRISM chip sets holding the majority of market share." PRISM technology is designed to comply with the IEEE’s 802.11 global standard, and Intersil is a founding sponsor of the Wireless Ethernet Compatibility Alliance (WECA), whose Wi-Fi™ brand is a mark of compatibility for 802.11-based systems. PRISM/work™ and PRISM/home™ products are used in WLAN systems from industry-leading companies including Alcatel, Cisco, Compaq, 3Com, Dell, D-Link, Nokia, Nortel, Samsung, Scientific-Atlanta, Siemens, SOHOware, SpectraLink, Symbol, and Zoom.
