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.
Figure 1.5 - Minimal Overlap Coverage Option
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 Wireless LAN Adapter) must
be configured with the same Service Set Identifier (SSID) in
order to provide the roaming capability.
