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 PC Card) must be conﬁgured

with the same Service Set Identiﬁer (SSID) in order to pro-

vide the roaming capability.
