RF Auto-Tuning with Modelling, as with the RF Auto-Tuning 
technique, lets you set the auto tuning feature to adjust power and 
channel settings to provide RF signals to the coverage area for your 
users. Enhance the auto tuning feature by providing modelling 
information about your geographic location. By providing some 
information about your buildings and floors, you add enough details 
into 3WXM so that your can better visualize your network topology 
and support improved monitoring at your site. 
„
RF Planning is a technique you can use to create a detailed network 
plan that provides powerful monitoring and visualization benefits. 
Unlike RF Auto-Tuning or RF Auto-Tuning with Modelling, you do not 
rely on the auto tuning feature. Instead, you fully model your 
geographic location with detailed information about your floors, and 
specify your RF coverage areas and your RF obstacles. 
Each of these methods is described in the sections that follow.
RF Auto-Tuning
To use the RF Auto-Tuning technique:
„
Physically place WX switches and the MAPs in their desired locations. 
„
Upload a WX switch configuration and deploy it
„
Enable the RF Auto-Tuning feature
This is a great way to install a WX switch and some MAPs, and observe 
how the network operates. The RF Auto-Tuning plan is best suited to 
networks containing fewer MAPs.
RF Auto-Tuning with
Modelling
To use the RF Auto-Tuning with Modelling technique, you add to the RF 
Auto-Tuning technique by providing some geographical modelling about 
your building, floors, and RF coverage area. You also add RF obstacle 
information for major obstacles (like concrete walls, windows, and 
elevator shafts) that affect attenuation—the quality of RF signals emitted 
from and received by the MAPs. 
By adding geographical modelling, you will be able to manage your 
network in the context of that geographical information. For example, 
you will be able to manage your network overlaid on a floor plan, versus 
managing an abstract logical group of switches and MAPs.
