Dell 6.2 manual Setting Description

3.Select Adaptive Radio Management (ARM) Profile.

4.Select the name of the profile you want to edit. The Adaptive Radio Management (ARM) profile window opens.

Configuration settings are divided into two tabs, Basic and Advanced. The Basic tab displays only those configuration settings that often need to be adjusted to suit a specific network. The Advanced tab shows all configuration settings, including settings that do not need frequent adjustment or should be kept at their default values. If you change a setting on one tab then click and display the other tab without saving your configuration, that setting will revert to its previous value. Both basic and advanced ARM configuration parameters are described in Table 97.

5.Change any of the settings described in the table below, then click Apply to save your changes.

Description

Basic Configuration Settings

Assignment	Activates one of four ARM channel/power assignment modes. (The default value is single-band.)
	• disable: Disables ARM calibration and reverts APs back to default channel and power settings
		specified by the AP’s radio profile
	• maintain: APs maintain their current channel and power settings. This setting can be used to
		maintain AP channel and power levels after ARM has initially selected the best settings.
	• multi-band: For single-radio APs, this value computes ARM assignments for both 5 GHZ (802.11a) and
		2.4 GHZ (802.11b/g) frequency bands.
	• single-band: For dual-radio APs, this value enables APs to change transmit power and channels
		within their same frequency band, and to adapt to changing channel conditions.
Allowed bands	The specified setting allows ARM to determine if 40 MHz mode of operation is allowed on the 5 GHz or 2.4
for 40MHz	GHz frequency band only, on both frequency bands, or on neither frequency band.
channels
Max Tx EIRP	Maximum 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. 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 will be reduced to the highest supported power
	setting. The default value for this parameter is 127 dBm.
	NOTE: Power settings will not change if the Assignment option is set to disabled or maintain.
Min Tx EIRP	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. Note that power settings will not change if the Assignment
	option is set to disabled or maintain. 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 will be reduced to the highest supported power setting. The default value for this
	parameter is 9 dBm.
	Consider configuring a Min Tx Power setting higher than the default value if most of your APs are placed
	on the ceiling. APs on a ceiling often have good line of sight between them, which will cause ARM to
	decrease their power to prevent interference. However, if the wireless clients down on the floor do not
	have such a clear line back to the AP, you could end up with coverage gaps.
Scanning	The Scanning checkbox enables or disables AP scanning across multiple channels. This checkbox is
	selected by default. Do not disable scanning unless you want to disable ARM and manually configure AP
	channel and transmission power. Disabling this option also disables the following scanning features:
	•	Multi Band Scan
	•	Rogue AP Aware
	•	Voip Aware Scan
	•	Power Save Scan
