The MAPs on a floor plan in RF Planning are color coded to indicate their
monitored status:
Green—Up
Yellow—Up (but with minor service degradation)
Orange—Up (but with major service degradation)
Red—Down
Blue—Unknown
A MAP with a blue background is not in the live network even though it
is on the floor plan. The channel number for this MAP will match the
channel number assigned by RF Planning. However, a MAP with a green
background is running in the live network, and the channel number of
this MAP will indicate the channel on which the MAP is operating, which
is not necessarily the channel assigned by RF Planning.
If RF Auto-Tuning of channels is enabled, the channels can change on live
MAPs even if you do not change them.
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.
3Com recommends that you assign channels before you compute
optimal power, to ensure successful power computation.
If the MAP is using an external antenna, specify the antenna model and
the coverage direction of the antenna before computing power. See step
8 in "Configuring Advanced MAP Settings" on page 289.
To compute optimal power
1 In the Task List panel, click RF Planning.
2 Under RF Planning, click Compute Optimal Power.
The Compute Power For wizard appears, showing a list of the areas you
defined and the corresponding technology.
