162 CHAPTER 4: PLANNING THE 3COM MOBILITY SYSTEM
Computing Optimal
Power
If you do not plan to use the RF Auto-Tuning feature to automatically set
the power levels on the MAPs after deployment and installation, use the
Compute Optimal Power option to calculate the power settings for the
MAPs.
Transmit power levels must be high enough to adequately cover an area,
but also low enough to minimize co-channel interference. 3WXM factors
in these considerations when calculating optimal power.
If you changed a MAP model to MP-341, MP-352, or MP-262 and you
are using an external antenna, specify the antenna model and the
direction of the antenna’s coverage before you compute power. See
step 4 in “To modify radio settings” on page 280.
To compute optimal power
1 On the Plan RF Coverage page, click Compute Optimal Power.
The Compute Power For wizard appears, showing a list of the areas you
defined and the corresponding technology.
2 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.
