After you import RF measurements and rebuild the attenuation library, 
you can look for coverage holes by displaying coverage. To locate 
coverage holes:

„

Display the optimized RF coverage area to view the results of the 
corrected attenuation data.

„

Lock down deployed MAPs in the coverage area (so that 3WXM will 
not move MAPs in your network plan during the compute and place 
process).

„

Compute and place MAPs.

„

Replan your network based on compute and place results.

Display the RF coverage area to view the RF coverage based on the 
corrected attenuation data.

1 Select the RF Planning option in the main 3WXM tool bar.

2 Display the floor plan in the Content panel.

3 In the Task List panel, click RF Planning.

4 In the Show RF coverage using listbox, select how you want to display the 

coverage:

„

Baseline Association Rate—Coverage is shown based on the MAP 
radio baseline association rate. The baseline association rate is the 
typical data rate the radio is expected to support for client 
associations. (The baseline association rate is specified during 
planning, on a coverage area basis.) 

„

Data Rate—Coverage is shown in colored bands that represent each 
of the data transmit rates supported by the radio. These rates are 
standard for each radio type. 

„

RSSI—Coverage is shown based on the received signal strength 
indication (RSSI) of the radio’s signal heard by other radios. 

5 In the Coverage Areas section of the Organizer panel, select the scope for 

which you want to display coverage. You can display coverage for an 
individual radio, a specific coverage area, or all coverage areas on the floor.

To select multiple noncontiguous objects, click Ctrl while selecting.
