Broadcom Adds Gigabit Ethernet Wi-Fi(R) Processor to Its Intensi-fi(TM) Family of Draft-802.11n Solutions

New Network Processor Enables Industry-Leading Wi-Fi Router Performance,

Expanding the Possibilities of the 802.11n Standard

    IRVINE, Calif., Dec. 6 /PRNewswire-FirstCall/ -- Broadcom Corporation
 (Nasdaq:   BRCM), a global leader in semiconductors for wired and wireless
 communications, today announced a new Wi-Fi(R) Gigabit Ethernet (GbE)
 processor that extends its Intensi-fi(TM) family of draft-802.11n
 solutions. Although current generations of 802.11n products deliver 4 times
 the throughput of 802.11g, performance is actually bottlenecked by the Fast
 Ethernet switch and network processor. By integrating a GbE controller and
 increasing the processor's clock speed, Broadcom's latest offering
 eliminates those bottlenecks, allowing the system to achieve the
 theoretical maximum wireless 802.11n performance, nearly 8 times that of
 802.11g. The new Broadcom(R) Wi-Fi GbE processor is available today in
 products from leading OEMs, including Linksys and Buffalo.
     In real world tests conducted by Broadcom and validated by a
 third-party testing company, products powered by the new Broadcom BCM4705
 GbE processor produced industry leading Wi-Fi throughput in excess of 160
 Megabits per second (Mbps). In addition, highlighting the power of the
 Intensi-fi architecture, these products have also demonstrated a consistent
 data throughput of up to 200 Mbps and achieved over 250 Mbps in a
 simultaneous dual band configuration in "clean air" laboratory tests.
     "The performance of draft-802.11n wireless routers shouldn't be gated
 by associated networking components that can keep these products from
 reaching the performance targets of the forthcoming 802.11n standard," said
 Rahul Patel, Director of Marketing for Broadcom's Wireless LAN business
 unit. "By offering the industry's highest performing Wi-Fi network
 processor, Broadcom is enabling manufacturers to deliver premium access
 points, routers and residential gateways that deliver the full value of
 802.11n networking."
     Announced today is the BCM4705 network processor, the latest addition
 to Broadcom's popular Intensi-fi family of IEEE draft-802.11n solutions
 that are currently found in nearly 70 percent of draft-802.11n routers and
 client devices(1). The new network processor provides a significant boost
 in performance compared to other draft-802.11n processors, while
 maintaining compliance with the current draft of the standard. Products
 based on the BCM4705 will provide the bandwidth needed to wirelessly stream
 high definition video content throughout a typical home and support the
 increasingly diverse ecosystem of Wi-Fi products being adopted by
     Product Information
     The highly integrated BCM4705 processor combines a powerful 300 MHz/500
 DMIPS MIPS32(R) core and Gigabit Ethernet controller to provide high-speed
 routing and bridging capabilities. When implemented with Broadcom's
 best-in-class Intensi-fi radio and media access controller/baseband chips,
 the BCM4705 processor can substantially enhance the throughput of devices
 connected to a Gigabit network -- providing greater than 160 Mb/s of TCP/IP
 throughput for wireless clients while also offering Gigabit Ethernet speeds
 for wired clients.
     Broadcom's flexible draft-802.11n processor platform provides several
 configuration and connectivity options that enable manufacturers to balance
 performance and cost in developing router/gateway products. The dual-band
 BCM4705 processor supports 2.4 and/or 5 GHz radios and accommodates 2X2,
 3X3 and 4�4 antenna configurations, enabling single band, dual band, or
 simultaneous dual band Wi-Fi routers. The chip also integrates USB 2.0
 host/device interfaces, enabling dynamic end products that allow end users
 to add several application specific peripherals such as printers, network
 attached storage, and digital cameras, to the Wi-Fi or wired network.
     Like all of Broadcom's award-winning Wi-Fi solutions, the BCM4705
 processor utilizes a highly integrated, all-CMOS architecture that enables
 cost-effective, high volume manufacturing. In addition, the BCM4705
 processor supports Broadcom's proven OneDriver(TM) software, which not only
 provides a consistent driver platform for manufacturers, but also delivers
 superior performance, ease-of-use and security features. One such feature
 is SecureEasySetup(TM) software, which enables users to configure their
 Wi-Fi networks and activate WPA(TM) security with the push of a button.
 OneDriver software also supports Wi-Fi Multimedia (WMM(TM)), which provides
 important quality of service (QoS) features by prioritizing audio, video
 and voice traffic on a Wi-Fi network.
     Broadcom's Wireless LAN Product Family
     Broadcom's high performance AirForce(TM) wireless LAN product line
 includes 54g(R) (the world's most popular Wi-Fi technology), and Intensi-fi
 (the industry's leading draft-802.11n chipsets, In
 addition to transceiver solutions that provide single and dual band
 wireless connectivity, Broadcom integrates wireless network processors,
 communications technologies and its OneDriver software solutions into
 reference designs that speed customer time-to-market. The industry's
 leading manufacturers are developing computers, routers, peripherals,
 phones, broadband modems and a variety of consumer electronics devices
 connected by Broadcom technologies.
