Designed for client devices based on the PCI Express architecture, the Broadcom BCM4311 is a high-performance 802.11a/g baseband processor with an integrated media access controller (MAC). The highly-integrated solution delivers superior performance, range and ease-of-use in a small, cost-effective package -providing design flexibility for wireless-enabled notebook PCs, printers and other client devices.PCI Express is a state-of-the-art bus architecture that addresses the needs of next-generation computing and communications products. Whereas today's embedded applications push the limits of the parallel PCI architecture, PCI Express uses serial interconnect technology to deliver higher bit rates that are better suited for performance-intensive multimedia applications. The PCI Express architecture also offers greater scalability, due to its low-cost, low pin-count design and software compatibility with existing PCI infrastructure.
