Adaptive Tx Power Control
Since ATPC can only reduce transmit power (not amplify it), optimal place-
ment of access points will provide full coverage at a transmit power level
somewhat below the maximum.
Furthermore, if the deployment needs to be able to remediate conditions such
as the failure or down-time of individual access points, the density should be
such that ATPC can compensate for a missing unit by lessening power reduc-
tion, thus allowing transmit power to increase towards its maximum.
For detailed examples of configuring , see Appendix C, “Adaptive Tx Power
Control Use Cases”.
Web: Configuring Adaptive Tx Power Control
The Adaptive Tx Power Control section of the Radio – Advanced Settings pop-
up window, shown in Figure 6-9, enables you to adjust the following settings
to configure ATPC characteristics:
■ Adaptive Tx Power Control: Enables and disables Adaptive Tx Power
Control on the selected radio. (The default is Disabled.)
■ Avoid Neighbor APs: When this setting is enabled, ATPC adapts to all
neighboring APs; RF Group Names and SSIDs are ignored. When this
setting is disabled, ATPC uses RF Group Name or SSIDs to determine
which APs to accommodate. (The default is Disabled.)
■ Adaptive Mode: Selects between AP mode and AP + Clients mode. In AP
mode, beacons and data transmissions are sent at the same power level.
In AP + Clients mode, beacons are transmitted at full power to maximize
the radio’s coverage area while data transmissions are at reduced power
to minimize co-channel contention. (The default is AP mode.)
■ RF Group Name: The name used to group APs for Adaptive Transmit
Power Control. (The default is blank.)
■ Max Tx Power Reduction: The maximum amount of power attenuation,
from 0-18dB. (The default is 18dB.)
■ [Update]: Updates the AP with all advanced radio settings.
