Silicon, Software Platform Offers Complete 802.11n Solution

An end-to-end unified silicon and software solution provides a complete platform for OEMs to design and bring to market a unified 802.11n enterprise wireless network. The solution includes three new products: the BCM56520 unified wireless switch, the Intensi-fi BCM4748 802.11n access point system-on-a-chip with Accelerange technology, and Fastpath 6.0 Unified Wireless Switching software optimized for the application. The BCM56520, the sixth generation of the StrataXGS Ethernet switch family, is a highly integrated multi-layer switch. It enables OEMs to create edge switches at cost points that eliminate the need for special or additional components. The BCM56520 includes up to 28 Gigabit Ethernet ports and six HiGig2 ports that can connect to other devices. The BCM4748 accelerates time-to-market and reduces development costs. It combines an 802.11n medium access controller, a baseband processor, a dual-band radio, a MIPS74K CPU, a GbE MAC, power amplifiers, and other WLAN components on one die. The whole platform in managed by Fastpath 6.0, which incorporates wireless visualization software that enables centralized management for unified edge switching, rather than controller-based switching. This offers better scaling in the network so it can be managed through one switch interface although the duties are actually distributed to all the switches in the network. The BCM56520, BCM4748, and Fastpath 6.0 are sampling now to early access customers. BROADCOM CORP., Irvine, CA. (949) 926-5000.
