Roaming, where the client can move from one Access Point to another in the same
wireless network without losing LAN connectivity.

Roaming over multiple channels. The RoamAbout PC Card automatically uses the
same channel as the associated Access Point.

The RoamAbout PC Card is also used in a RoamAbout Access Point as the wireless
port to provide wireless communication. For this manual, the Access Point with the PC
Card are usually considered one unit.
Wireless Infrastructure Network
In a wireless infrastructure network, wireless clients communicate with an Access Point to
connect to a wired LAN. A RoamAbout wireless infrastructure network can support clients
with various operating systems, such as Windows 95, Windows 98, Windows NT,
Windows 2000, MS-DOS, Windows 3.1, WinCE, Linux, and Apple Macintosh.
The area where a client can communicate with the Access Point is called a coverage area.
To increase the coverage area, you can add Access Points to the wireless network.
Single Access Point
You can have one wireless infrastructure network with one Access Point. Each wireless
client must communicate with the Access Point to connect to the wired network.
You can also have multiple wireless infrastructure networks, each with a single Access
Point and different wireless names. Each network is a separate entity. Clients cannot roam
between networks.
