Measurements to the

Floor Plan

1Under 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-generatedand 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.)

2Click 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.
