208 Optimizing a Network PlanNN47250-101 (320665-G Version 02.01)• If the number is 0, no measurements were imported. Try the import again. If you are using asite survey file, verify that the map name is correct.After you import your RF measurements, you correct the attenuation factors for the floor. Go to “Optimizing the RFCoverage Model” next for information about this topic.Optimizing the RF Coverage ModelAn attenuation library is a set of attenuation values for the RF obstacles on a floor. After you import RF measurementsfrom a site survey or apply them from the RF measurements in your network to your network plan, you rebuild a floor’sattenuation library using those RF measurements.1 Display the floor plan in the Content panel.2 In the Task List panel, click RF Planning.3 Under Site Survey in the Task List panel, click Optimize. A wizard appears, listing the progress of therequest.Note. The RF Planning software does not support outdoor installations. RFobstacles typically found in outdoor environments have not been adequatelytested for their attenuation characteristics. As a result, the database cannot ensureaccurate attenuation coefficients for RF planning purposes. Nortel does notwarrant or support any outdoor deployments or installations of the WLAN 2300system implemented with the use of this tool.
