Network Configurations Using Client Adapters
Wireless Infrastructure with Workstations Accessing a Wired LAN
A microcellular network can be created by placing two or more access points on a LAN. Figure 1-2
shows a microcellular network with workstations accessing a wired LAN through several access points.
This configuration is useful with portable or mobile stations because it enables them to be directly
connected to the wired network even while moving from one microcell domain to another. This process
is transparent, and the connection to the file server or host is maintained without disruption. The mobile
station stays connected to an access point as long as it can. However, when the transfer of data packets
needs to be retried or beacons are missed, the station automatically searches for and associates to another
access point. This process is referred to as seamless roaming.
