Min Transmit Power
This indicates the minimum effective isotropic radiated power (EIRP) from 3 to 33 dBm in 3 dBm increments.
You may also specify a special value of 127 dBm for regulatory maximum to disable power adjustments for
environments such as outdoor mesh links. Higher power level settings may be constrained by local regulatory
requirements and AP capabilities. In the event that an AP is configured for a Min Tx EIRP setting it cannot
support, this value is reduced to the highest supported power setting.
The default value is18 dBm.
Max Transmit Power
This indicates the maximum effective isotropic radiated power (EIRP) from 3 to 33 dBm in 3 dBm increments.
Higher power level settings may be constrained by local regulatory requirements and AP capabilities. In the event
that an AP is configured for a Max Tx EIRP setting it cannot support, this value is reduced to the highest
supported power setting.
Default value: 127 dBm
Client Aware
When Enabled , Adaptive Radio Management (ARM) does not change channels for the Access points when the
clients are active, except for high priority events such as radar or excessive noise. This should be enabled in most
deployments for a stable WLAN.
If the Client Aware mode is Disabled , the IAP may change to a more optimal channel, but this change may also
disrupt current client traffic.
The Client Aware option is Enabled by default
Scanning
When ARM is enabled, the IAP dynamically scans all 802.11 channels within its 802.11 regulatory domain at
regular intervals and will report everything it sees to the IAP on each channel it scans. This includes, but is not
limited to, data regarding WLAN coverage, interference, and intrusion detection.
Wide Channel Bands
This feature allows administrators to configure 40 MHz channels in the 2.4 GHz and 5.0 GHz bands. 40 MHz
channels are essentially two 20 MHz adjacent channels that are bonded together. 40 MHz channel effectively
doubles the frequency bandwidth available for data transmission.
Monitoring the Network with ARM
When ARM is enabled, an IAP dynamically scans all 802.11 channels within its 802.11 regulatory domain at
regular intervals and provides reports for network (WLAN) coverage, interference, and intrusion detection, to a
Virtual Controller.
ARM Metrics
ARM computes coverage and interference metrics for each valid channel and chooses the best performing
channel and transmit power settings for each IAP RF environment. Each IAP gathers other metrics on their
ARM-assigned channel to provide a snapshot of the current RF health state.
NOTE:
When the Client Aware ARM is disabled, channels can be changed even when the clients are active on BSSID.
