„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 this MAP’s channel number 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

MPs even if you do not change them.

Computing Optimal If you do not plan to use the RF Auto-Tuning feature to automatically set Power 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 direction of the antenna’s coverage before you compute power. See step 8 in “Configuring Advanced MAP Settings” on page 277.

To compute optimal power

1In the Task List panel, click RF Planning.

2Under RF Planning, click Compute Optimal Power.

The Compute Power For wizard appears, showing a list of the areas you defined and the corresponding technology.
