New Network Processor Enables Industry-Leading Wi-Fi Router Performance, Expanding the Possibilities of the 802.11n Standard
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 consumers.
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.
