LAN

High-performance processor allows wireless access points and

routers to run in IEEE 802.11a and IEEE 802.11g modes

simultaneously.

Architecture optimized for wire-speed routing.

Ideal platform for enterprise access points.

10/100 Ethernet WAN to 10/100 Ethernet LAN routing with

optional expansion to 4/8/16-port Ethernet LAN.

Modem codec interface enables low-cost software modem.

V.92 codec interface is compatible with AC'97 or serial-based

hardware to leverage homologated modules.

PCI 2.3 host interface expands platform up to three external PCI

devices.

12-Mbps, USB 1.1-compliant host/device interface enables

expansion for printer and camera servers, and wireless Webcam
