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 importing RF measurements and optimizing, look for coverage
holes by displaying coverage.
Locating a Coverage
Hole
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 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) heard by other radios.
4 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.
