3 To optimize the AP count, select Optimize AP Count. This option checks
for coverage overlaps and removes a MAP if neighboring MAPs provide
enough coverage to make the MAP unnecessary.
This option applies only to coverage areas that are configured for
coverage, not capacity. Unless you disabled the option to place MAPs
based on capacity, do not select the Optimize AP Count option.
4 Select Compute Power for the areas for which you want to compute
power.
5 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" on page 156.
