478 CHAPTER 18: OPTIMIZING A NETWORK PLAN
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.
Locating and Fixing Coverage Holes
After you import RF measurements and optimize, you can look for
coverage holes by displaying coverage.
Locating a Coverage
Hole
To locate a coverage hole:
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.
