Selecting the Locations for Multiple APs
Consider the following:
• Each coverage area must overlap another coverage area to allow roaming for clients.
• The amount of overlap depends on number of users in a coverage area and utilization
of the network.
If you expect that one coverage area has more users or higher network utilization than
the other coverage areas, increase the overlap of the adjacent coverage areas by
moving the APs closer together (see Figure 3-2).
Figure 3-2: Overlapping Coverage Areas
• If possible, have the adjacent APs whose coverage areas overlap use different channels
that are at least five channels apart.
• Be aware of potential hidden station problems. If possible, arrange the coverage area
to minimize or prevent any two clients from being within range of the AP but out of
range with each other.
For best placement, configure the AP and a client and use the procedure in the “Optimizing
RoamAbout AP Placement” on page 6-5 before permanently mounting the AP.
Before mounting the AP, review the hardware requirements described in the installation
documentation that shipped with the RoamAbout AP.
NOTE: If you are using two PC cards in the RoamAbout R2, they must
be five channels apart.
