Aironet Wireless Communications, Inc. 1-4 Confidential and Proprietary
By arranging AP4500/4800 access points such that the overlap in coverage area is nearly maximized, a
large number of mobile clients can be supported in the same general coverage area without any
degradation in system performance or connect time. In addition, due to the redundancy in coverage
overlap, system performance is not hampered in the event of an access point failure because clients will
automatically ‘roam’ to an operational access point. With this architecture, all access points and
PC4500\4800s must be configured with the same system identifier. The maximum available bandwidth
will be the sum of that available from each AP4500/4800 with overlapping coverage areas.
Figure 1.3 - Multiple Overlapping Systems Coverage Option
Multiple systems can operate in the same vicinity by arranging AP4500/4800 access points such that the
overlap in coverage area is as desired. The PC4500/4800-AP4500/4800 architecture provides multiple
channels, which can exist in the same area with virtually no interference to each other. In this mode,
each system must be configured with different system identifiers, which prevents PC4500/4800 clients
from roaming to the access points of a different network. This architecture is useful in circumstances
where different classes of users do not have access to the same network (such as manufacturing and
inventory and design engineering may be on separate networks).
Refer to the User Guide and Technical Reference Manual, PC4500/4800 (DOC 710-004239) for
additional details on these standard architectures and Aironet products.
