136CHAPTER 6: USING RF PLANNING
Assign Channel After identifying the MAP access points required for a coverage area, you Settings need to assign channels to the MAP access points.
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 neighboring MAPs (including MAPs 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. 3WXM uses predicted RSSI values for the imaginary “ray” that is drawn between two MAPs. Consequently, you may see unexpected results if the exact path between the MAPs has many obstacles, but the areas around that path are relatively open. You can make further manual adjustments, if necessary.
To assign channels:
1The Organizer panel is displayed on the left. Expand Sites, right-click on a building, and select Edit.
The Modify Building wizard is displayed.
2Select the Plan RF Coverage tab; then click Assign Channels to MAPs.
The Channel Assignment wizard appears, showing the current channel assignment constraints.
