Wired and wireless broadband communications player Broadcom has announced what it claims is the first Wi-Fi chipset to supports the PCI Express bus architecture. By introducing the first PCI Express-compliant Wi-Fi chipset, Broadcom hopes PC manufacturers will begin building next-generation wireless notebooks that take advantage of this high-speed bus architecture. The Broadcom BCM4311 PCI Express enabled 802.11a/g baseband processor has an integrated media access controller (MAC). It is also built with an extremely small footprint that is intended to provide design flexibility for wireless-enabled notebook PCs, printers and other client devices. Broadcom says the BCM4311 offers all of the benefits of the PCI Express bus architecture, while continuing to deliver the superior performance, range and ease-of-use found in all 54g solutions. The new chip features BroadRange technology, an advanced digital signal processing technique that allows devices based on 54g technology to stay connected at distances up to 50% farther from a wireless router than previous generation solutions. The BCM4311 also supports Broadcom's OneDriver software, which offers a number of features to improve performance, security and ease-of-use for Wi-Fi networks including SecureEasySetup. “As the industry readies itself for a new era of high-performance computing, Broadcom is delivering a host of wired and wireless solutions that support PCI Express,” says Jeff Abramowitz, senior director of marketing for Broadcom’s Home & Wireless Networking Business Unit. “By providing early access to the most advanced technologies, we enable our customers to get a head-start in building next-generation wireless products that make the most of the PCI Express bus architecture,” he adds. The BCM4311 is now sampling to early access customers.
