32 CHAPTER 2: PLANNING AND MANAGING YOUR WIRELESS NETWORK WITH 3WXM
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.
