the Virtual Controller determines the distribution of clients and balances client load across channels, regardless of

whether the AP is responding to the wireless clients' probe requests.

With this feature, the client load for an AP is determined based on the value specified for the SLB threshold. When

the client load on an AP reaches or exceeds the SLB threshold in comparison to its neighbors, or if a neighboring AP

on another channel does not have any clients, load balancing is enabled on that AP, to allow clients to connect to an

available or less loaded channel. When the client count reaches the threshold, the APs with load balancing enabled

will not send probe response or authentication response to the new client requests.

Airtime Fairness Mode

The Airtime Fairness feature provides equal access to all clients on the wireless medium, regardless of client type,

capability, or operating system, thus delivering uniform performance to all clients. This feature prevents the clients

from monopolizing resources.

Access Point Control

The following access point control features are supported:

l Customize Valid Channels — You can customize Valid 5 GHz channels and Valid 2.4 GHz channels for

20MHz and 40MHz channels in the OAW-IAP. The administrators can configure the ARM channels in the

channel width window. The valid channels automatically show in the static channel assignment window.

l Minimum 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. A higher power level setting may be

constrained by the local regulatory requirements and AP capabilities. If the minimum transmission EIRP setting

configured on an AP is not supported by the AP model, this value is reduced to the highest supported power

setting. The default value is for minimum transmit power is 18 dBm.

l Maximum 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. If the maximum transmission EIRP configured on an AP is not supported by the AP model,

the value is reduced to the highest supported power setting. The default value for maximum transmit power is 127

dBm.

l Client Aware — When Enabled, ARM does not change channels for the APs with active clients, except for high

priority events such as radar or excessive noise. This feature must be enabled in most deployments for a stable

WLAN. If the Client Aware mode is Disabled, the OAW-IAP may change to a more optimal channel, which

change may disrupt current client traffic for a while. The Client Aware option is Enabled by default.

When the Client Aware ARM is disabled, channels can be changed even when the clients are active on a

BSSID.

l Scanning — When ARM is enabled, the OAW-IAP dynamically scans all 802.11 channels within its 802.11

regulatory domain at regular intervals and reports to the OAW-IAP. This scanning report includes WLAN

coverage, interference, and intrusion detection data.

l 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OAW-IAP dynamically scans all 802.11 channels within its 802.11 regulatory domain at

regular intervals and sends reports to a Virtual Controller on network (WLAN) coverage, interference, and intrusion

detection.
