Configuring Tx Power Levels
The Current Tx Power Level setting controls the maximum conducted transmit power. The maximum
available transmit power varies according to the configured channel, individual country regulation, and
access point capability. Refer to the Product Guide or data sheet at www.cisco.com for each specific
model in order to determine the access point capability.
The Current Tx Power Level setting of 1 represents the maximum conducted power setting for the access
point. Each subsequent power level (e.g. 2, 3, 4, etc) represents approximately a 50% (or 3dBm)
reduction in transmit power from the previous power level.
Note The actual power reduction may vary slightly for different models of access points.
Table 5-28 RF Channel Assignment
Parameter Description
Current Channel Channel number of the access point.
Note The channels 1, 6, and 11 are non-overlapping.
Assignment Method Select one of the following:
• Global—Use this setting if your access point’s channel is set
globally by the controller.
• Custom—Use this setting if you set the channel locally.
Note The assignment method should normally be left at the global setting. This allows the controller
to dynamically change the channel number based Radio Resource Management (RRM)
directives.
Table 5-29 Tx Power Level Assignment
Parameter Description
Current Tx Power Level The transmit power level of the access point. Tx Power Level indicates
the maximum power.
Note The power levels and available channels are defined by the
Country Code setting, and are regulated on a country by country
basis.
Assignment Method Select one of the following:
• Global—Use this setting if your access point’s transmit power is set
globally by the controller.
• Custom—Use this setting if your access point’s transmit power is set
locally. Select an option from the drop-down list.
For example, if you select 2(17 dBm) as the custom power, 2
corresponds to the Power Level and 17 is the Absolute Power
(dBm).
Note The assignment method should be left at the global setting. This allows the controller to
dynamically change the transmit power level based on the Radio Resource Management
(RRM).
