Welcome to the Aironet 4000 Series Wireless LAN Adapter
Coverage Options
The system architecture options of the wireless station and Access Points provide for a variety of coverage alternatives and flexibility. The system can be designed to provide a wide coverage area with minimal overlap (Figure 1.5) or coverage with heavy overlap (Figure 1.6). The latter improves system performance and protection against down- time in the event of a component failure.

Wired LAN
By arranging the Access Points so the overlap in coverage area is minimized, a large area can be covered with minimal system cost. The total bandwidth available to each mobile station will depend on the amount of data each mobile sta- tion desires to transfer and the number of stations located in each cell. Seamless roaming is supported as a mobile sta- tion moves in and out of range of each Access Point, thereby maintaining a constant connection to the wired LAN. Each Access Point (and PC Card) must be configured with the same Service Set Identifier (SSID) in order to pro- vide the roaming capability.
