Installing the AT-WCU200G Wireless Adapter
Introduction
The AT-WCU200G wireless adapter is a standards-based wireless
product. See Figure 1. It can communicate with other devices enabled
for 802.11g and 802.11b standards-based wireless LAN connectivity. The
wireless adapter is fully compatible with the IEEE 802.11b RFC, so it can
be connected to your existing 802.11b-compliant devices.
402
Figure 1 AT-WCU200G Wireless Adapter
You can integrate the wireless adapter into an existing network by using
one of the following configurations:
❑ The ad-hoc mode which allows you to connect two PCs with a
wireless connection.
❑ The infrastructure mode which allows you to connect a PC with an
access point.
1
Ad-hoc Mode In the ad-hoc mode, you can enable a wireless connection between two
PCs. To accomplish this, you need one AT-WCU200G wireless adapter for
each PC. See Figure 2.
You can use a USB cable to connect the AT-WCU200G wireless adapter
to a workstation or laptop. Or, you can connect the AT-WCU200G
wireless adapter directly to the USB port on your PC.
