The BCM5354 provides wireless LAN connectivity that supports data rates of up to 125 Mbps that is backward-compatible with standard 802.11 b/g. The BCM5354 supports a WAN connection via its configurable media interfaces. The per-port programmable four-level priority queues enable QoS (IEEE 802.1p) for guaranteed bandwidth applications, DiffServ/ TOS, and L2/L3 IGMP snooping. The IEEE 802.1Q VLAN allows flexible implementation of VLAN grouping and WAN port segregation. Applications running on the BCM5354 leverage field-proven software which includes SecureEasySetup™ and comprehensive wireless network security support that comprises WEP/WPA/WPA2 encryption. The BCM5354 offers the industry’s most aggressive home router integration and enables the lowest bill of materials (BOM) solution cost. Broadcom’s superior technology and innovation also benefit manufacturers with faster time-to-market, and end products that are differentiated from the competition through rich features, exceptional range, and outstanding reliability.
