Applying the RF Measurements to the Floor Plan
1 Under Site Survey in the Task List panel, click Optimize.
A wizard appears, listing the progress of the request.
The Total number of RF measurements that did not intersect any
object line lists the number of measurements that did not
experience attenuation due to an RF obstacle in the path between
them.
object line lists the number of measurements that did not
experience attenuation due to an RF obstacle in the path between
them.
If the measurements came from a site survey file, they are
measurements between the portable AP (LOS point) and the PC
running the site survey tool. If the measurements came from MAP
radios in the network, they are measurements between MAP
radios.

The Total number of objects that will be corrected line indicates the
number of measurements that did experience attenuation. For
existing RF objects, 3WXM corrects the attenuation to match the
results. If the floor plan does not have an RF obstacle where the
attenuation library indicates one exists, 3WXM creates an RF
obstacle.

For RF obstacles created by 3WXM, the description is
auto-generated and the obstacle type is Other. You can edit
these values by selecting the obstacle, clicking the Edit properties
icon to open the Modify RF Obstacle wizard, and modifying the
values. Click OK to close the wizard and save the changes. (See
“To use the Create RF Obstacle Dialog box” on page 96. The
wizard is the same whether it is labeled Create or Modify.)

Defining Wireless
Coverage Areas
Coverage Areas
You must define which areas of your enterprise require wireless network
coverage. In 3WXM, you plan for both coverage and capacity
requirements in a particular area on the floor. Capacity requirements are
determined by the number of users in the area and the amount of
wireless network bandwidth desired for every user.

requirements in a particular area on the floor. Capacity requirements are
determined by the number of users in the area and the amount of
wireless network bandwidth desired for every user.
The floor of a building can contain multiple coverage areas if several
groups of users on the floor require different bandwidth. For example, an
engineering department might have its own coverage area to
accommodate a need for higher bandwidth, but the rest of the floor
might be planned for general use with lower bandwidth requirements.
