1-3 System Configurations

The WLAN-9100 Wireless Access Point can be configured in a variety of network system
configurations.

Wireless Infrastructure

In a wireless infrastructure, the WLAN-9100 acts as a bridge. The Access Point connects the

wireless clients together. The WLAN-9100 Access Point acts as a center point for all

wireless communications. This would increase efficiency of the communications since the

wireless adapters do not need to be within direct range of each other.

Wireless Infrastructure with Stations Attaching to a Wired LAN

The WLAN-9100 Wireless LAN Access Point will provide access to a your local LAN. An

integrated wireless and wired LAN is called an Infrastructure configuration. A group of

wireless LAN PC users and an Access Point construct a Basic Service Set (BSS). Each

wireless PC in this BSS can talk to any computer on your network via the Access Point.
