Locating and Fixing Coverage Holes
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.
Displaying the RF
Coverage Area
Display the RF coverage area to view the RF coverage based on the
corrected attenuation data.
To display the RF coverage area
1Select the RF Planning option in the main 3WXM tool bar.
2Display the floor plan in the Content panel.
3In the Task List panel, click RF Planning.
4In 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.
5In 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 contiguous objects, click Shift while selecting.
To select multiple noncontiguous objects, click Ctrl while selecting.
