A Typical Extricom Wireless Network Topology

Extricom’s switch is connected to the wired LAN, and the APs spread throughout the enterprise.

Figure 7

displays a typical Extricom enterprise topology, consisting of an Extricom switch and

eight APs.

Figure 7. Typical Extricom Typology

Extricom uses standard WLAN protocols (IEEE 802.11). As a result, any 802.11a/b/g standard
wireless device can work seamlessly with the Extricom system.
