Channel Plan Define a channel plan for the AP to be used when auto is selected
in the Channel drop-down menu. 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. Select one
of the following:
• All (Radio 1 only) — ACS will scan all the channels for an
operating channel.
• All Non-DFS (Radio 1 only, default) — ACS scans all non-DFS
channels for an operating channel. This selection is available
when there is at least one DFS channel supported for the
selected country. (default)
• 3 Channels (Radio 2 only) — the three channels are 1,6, and
11 in NAM and 1,7, and 13 in ROW.
• 4 Channels (Radio 2 only) — the four channels are 1,4,8,abd
11 in NAM and 1,5,9,and 13 in ROW.
• Auto (Radio 2 only, default) — ACS automatically selects the
3-channel plan on NAM devices and the 4-channel plan on
ROW devices.
• Custom — If you want to configure individual channels from
which the ACS will select an operating channel, click
Configure. The Add Channels dialog displays. Select the
individual channels you want to add to the channel plan while
pressing the CTRL key, and then click Close.
Configure Click to define a custom channel plan for the radio.
Automatic Tx Power Control
(ATPC)
Select to enable/deselect to disable ATPC. ATPC automatically
adapts transmission power signals according to the coverage
provided by the
APs. After a period of time, the system stabilizes
itself based on the RF coverage of your APs.
ATPC guarantees your LAN a stable RF environment by
automatically adapting transmission power signals according to
the coverage provided by the
APs.
ATPC is disabled by default.
Max Tx Power Select the maximum Tx power level to which the range of transmit
power can be adjusted. It is recommended to not limit the potential
Tx power level range that can be used.
Min Tx Power Select the minimum Tx power level to which 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. The Min Tx Power drop-down menu only displays if
Automatic TX Power Control (ATPC) is selected.
ATPC Adjust Select 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 recommends Tx power levels for each 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. The
ATPC Adjust drop-down menu only displays if Automatic TX
Power Control (ATPC) is selected. The default is +0 dBm.
