描述 Description

OPTIMIZED 802.11G ROUTER WITH BROADRANGE™
The BCM5354 integrates a high-performance MIPS32 processor, IEEE 802.11 b/g MAC/PHY, 2.4-GHz direct conversion radio, USB 2.0 host controller, SDRAM controller, and a configurable five-port Fast Ethernet (FE) switch.
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.FEATURES
