Assign Channel Settings
After identifying the AP required for a coverage area, you need to assign channels to the AP. Appropriate assignment of
channels across the floor minimizes co-channel interference. The channel assignment algorithm assigns non-overlapping
channels to neighboring APs from the selected channel set. Choose the starting floor and the ending floor (in the
downward direction) for multi-floor channel assignment. The algorithm takes predicted RSSI values between neigh-
boring APs (including APs on different floors and 3rd party APs) and minimizes same-channel assignments between
APs. You can specify cross-floor attenuation and the 802.11 technology on which you want to perform the channel
assignment. WMS uses predicted RSSI values for the imaginary “ray” that is drawn between two APs. Consequently,
you might see unexpected results if the exact path between the APs has many obstacles, but the areas around that path
are relatively open. You can make further manual adjustments, if necessary.

To assign channels
1
Display the floor plan in the Content panel.
2
In the Task List panel, click RF Planning.
3
Under RF Planning, click Assign Channels. The Channel Assignment wizard appears, showing the
current channel assignment constraints.
current channel assignment constraints.
4
To change the starting floor for channel assignment, select the floor from the Begin On Floor List. By
default, WLAN Management Software starts at the top floor and works down.
default, WLAN Management Software starts at the top floor and works down.
5
To change the ending floor for channel assignment, select the floor from the End On Floor List.
The ending floor number must be lower than or equal to the starting floor number.
6
To change the radio type for which to assign channels, select the radio type from the Technology list. By
default, WLAN Management Software assigns channels for all radio types on the AP placed in the
building.
