The measurements reflect how well the measuring MAPs can hear one 
another, and do not directly measure how well clients can hear the 
MAPs. For example, if the MAPs are mounted on the ceiling, attenuation 
of their signals to one another might be less than the attenuation of the 
same signals when received by clients on desktops in cubicles and offices.

After you import RF measurements and optimize, you can look for 
coverage holes by displaying coverage.

To locate a coverage hole:

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.
