Figure 1.6 - Heavy Overlap Coverage Option
By arranging the Access Points so the overlap in coverage
area is nearly maximized, a large number of mobile stations
can be supported in the same wireless infrastructure. How-
ever, units in overlapping coverage areas on the same fre-
quency will detect adjacent cell traffic and delay
transmissions that would cause collisions. This reduces the
aggregate radio system throughput. Heavy cell overlap is
not recommended for maximum system throughput. Due to
the redundancy in coverage overlap, system access is not
lost in the event of an Access Point failure. Upon failure of
the Access Point, the station will automatically roam to an
operational Access Point. With this architecture, all Access
Points and PC Card units must be configured with the same
Service Set Identifier (SSID).
