Configuring the Altitude AP
Last Requested Channel - This field displays the last wireless channel that you had selected for
the Altitude AP to communicate with the wireless devices.
Requested New Channel - Click the wireless channel you want the Altitude AP to use to
communicate with wireless devices.
Click Auto to request the ACS to search for a new channel for the Altitude APs, using a channel
selection algorithm. This forces the APs to go through the auto-channel selection process again.
Depending on the regulatory domain (based on country), some channels may be restricted. The
default value is based on North America. For more information, see
information."
Auto Tx Power Ctrl (ATPC) - Click to enable ATPC. ATPC automatically adapts transmission
power signals according to the coverage provided by the Altitude APs. After a period of time, the
system will stabilize itself based on the RF coverage of your Altitude APs.
Current Tx Power Level - This field is view only. It displays the actual Tx power level assigned
to the Altitude AP radio.
Max Tx Power - Click the maximum Tx power level that the range of transmit power can be
adjusted: 0 to 18 dBm. It is recommended to use 18 dBm to not limit the potential Tx power level
range that can be used.
Min Tx Power - If ATPC is enabled, click the minimum Tx power level that the range of transmit
power can be adjusted. It is recommended to use the lowest value available to not limit the
potential Tx power level range that can be used.
NOTE
The Minimum Tx Power level is subject to the regulatory compliance requirement for the selected country
Auto Tx Power Ctrl Adjust - If ATPC is enabled, click the Tx power level that can be used to
adjust the ATPC power levels that the system has assigned. It is recommended to use 0 dBm
during your initial configuration. If you have an RF plan that recommended Tx power levels for
each Altitude AP, compare the actual Tx power levels your system has assigned against the
recommended values your RF plan has provided. Use the Auto Tx Power Ctrl Adjust value to
achieve the recommended values.
Channel Plan - If ACS is enabled, you can define a channel plan for the Altitude AP. Defining a
channel plan allows you to limit which channels are available for use during an ACS scan. For
example, you may want to avoid using specific channels because of low power, regulatory
domain, or radar interference. Click one of the following:
All Channels - ACS will scan all the channels for an operating channel.
Custom - If you want to configure individual channels from which the ACS will select an
operating channel, click Configure. The Add Channels dialog is displayed. Click the
individual channels you want to add to the channel plan while pressing the CTRL key, and
then click OK.
