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).
