Dynamic Channel Selection - To enable Dynamic Channel Selection, click one of the following:
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 Altitude AP will cease
operating on the current channel and ACS is employed to automatically select an alternate
channel for the Altitude AP to operate on.
DCS Noise Threshold - Type the noise interference level, measured in dBms, after which ACS
will scan for a new operating channel for the Altitude AP if the threshold is exceeded.
DCS Channel Occupancy Threshold - Type the channel utilization level, measured as a
percentage, after which ACS will scan for a new operating channel for the Altitude AP if the
threshold is exceeded.
DCS Update Period - Type the time, measured in minutes that determines the period during
which the Altitude AP averages the DCS Noise Threshold and DCS Channel Occupancy
Threshold measurements. If either one of these thresholds is exceeded, then the Altitude 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 antennas. The default and recommended selection is Best. If only one
antennae 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 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, it is recommended to use either Left or Right for Tx
Diversity. If only one antennae is connected, use the corresponding Left or Right diversity
setting. Do not use Alternate if two identical antennas are not used.
Min Basic Rate - Click the minimum data rate that must be supported by all stations in a BSS: 6,
12, or 24 Mbps. If necessary, the Max Basic Rate choices adjust automatically to be higher or
equal to the Min Basic Rate.
