Applying The Rf Measurements To The Floor Plan - 3Com WX4400 Reference Manual

Applying the RF
Measurements to the
Floor Plan
To apply 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.
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.
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 102. The wizard is the same
whether it is labeled Create or Modify.)
2 Click Finish.
If the imported RSSI values do not match the values predicated by
3WXM, 3WXM looks for an RF obstacle in the plan that might be causing
attenuation, and adjusts its attenuation value in the plan so that the
predicted RSSI matches the measured RSSI. However, the following
should be noted:
The Optimize feature adjusts attenuation values only if the network
plan has an RF obstacle in the line of sight between measurement
points (for example, between MAPs that made the measurements).
3WXM does not create an obstacle to account for the RSSI if one does
not already exist.
Only one obstacle between any two measurement points is adjusted,
even if there are multiple obstacles between the measurement points.
