This option applies only to coverage areas that are configured for
coverage, not capacity. (This is configured on the Area Properties page of
the Coverage Area wizard.) Unless you disabled the option to place MAPs
based on capacity, do not select the Optimize AP Count option.
3 Select Compute Power for the areas for which you want to compute
power.
4 Click Next. The Compute Power For Progress page appears.
If the power computation succeeds, click Finish to see the results.
If the power computation fails, click OK in the Optimal Power
Computation box, and click Finish. See "To resolve optimal power
computation problems".
If the power computation is successful, the updated power levels are
reflected in the Coverage Areas panel in the Plan RF Coverage page.
5 To include third-party access points in the network plan, see "Adding a
Third-Party Access Point" on page 148.
To resolve optimal power computation problems
If power levels for one or more coverage areas could not be optimized,
show the RF coverage at baseline association and minimum transmit rates
for the coverage areas by doing the following:
1 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.
2 In the Coverage Areas section, 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.
