Infrastructure Wireless LAN for Roaming Wireless PCs

– 36 –

The infrastructure configuration extends the accessibility of wireless PCs to

the wired LAN.

A wireless infrastructure can be used for access to a central database, or

for connection between mobile workers, as shown in the following figure.

IRELESS

The Basic Service Set (BSS) defines the communications domain for each

access point and its associated wireless clients. The BSS ID is a 48-bit

binary number based on the access point’s wireless MAC address, and is

set automatically and transparently as clients associate with the access

point. The BSS ID is used in frames sent between the access point and its

clients to identify traffic in the service area.

The BSS ID is only set by the access point, never by its clients. The clients

only need to set the Service Set Identifier (SSID) that identifies the service

set provided by one or more access points. The SSID can be manually

configured by the clients, can be detected in an access point’s beacon, or

can be obtained by querying for the identity of the nearest access point.

For clients that do not need to roam, set the SSID for the wireless card to

that used by the access point to which you want to connect.

A wireless infrastructure can also support roaming for mobile workers.

More than one access point can be configured to create an Extended

Service Set (ESS). By placing the access points so that a continuous
