Dynamic Channel Selection Click one of the following:
Off — Disables DCS.
Monitor Mode — If traffic or noise levels exceed the configured
DCS thresholds, an alarm is triggered and an information log is
generated.
Active Mode — If traffic or noise levels exceed the configured
DCS thresholds, an alarm is triggered and an information log is
generated. In addition, the Wireless AP will cease operating on
the current channel and ACS will automatically select an alternate
channel for the Wireless AP to operate on.
DCS Noise Threshold — If DCS is enabled, type the noise
interference level, measured in dBm, above which ACS will scan
for a new operating channel for the Wireless AP if the threshold is
exceeded.
DCS Channel Occupancy Threshold — If DCS is enabled, type
the channel utilization level, measured as a percentage, above
which ACS will scan for a new operating channel for the Wireless
AP if the threshold is exceeded.
DCS Update Period — If DCS is enabled, type the time,
measured in minutes that determines the period during which the
Wireless AP averages the DCS Noise Threshold and DCS
Channel Occupancy Threshold measurements. If either one of
these thresholds is exceeded, then the Wireless AP will trigger
ACS.
Rx Diversity Click Best for the best signal from both antennas, or Left or Right
to choose either of the two diversity receiving antennas. The
default and recommended selection is Best. If only one antenna is
connected, use the corresponding Left or Right diversity setting.
Do not use Best if two identical antennas are not used.
Tx Diversity Click Alternate for the best signal from both antennas, or Left or
Right to choose either of the two diversity receiving antennas.
The default selection is Alternate that maximizes performance for
most clients. However, some clients may behave oddly with Tx
Diversity set to Alternate. Under those circumstances, Siemens
recommends that you use either Left or Right for Tx Diversity. If
only one antenna is connected, use the corresponding Left or
Right diversity setting. Do not use Alternate if two identical
antennas are not used.
Preamble Click a preamble type for 11b-specific (CCK) rates: Short, Long,
or Auto. The recommended value is Auto. Click Short if you are
sure that there is no 11b APs or client in the vicinity of this AP.
Click Long if compatibility with 11b clients is required.
Protection Mode Click a protection mode: None, Auto, or Always. The default and
recommended setting is Auto. Click None if 11b APs and clients
are not expected. Click Always
if you expect many 11b-only
clients.
