Chapter 1 Cisco Aironet 1000 Series Access Points
Channels and Maximum Power Levels
Step 5 On the left side of the screen under Access Points, click 802.11a Radios or 802.11b/g Radios and a list
of accociated access points appears.
Step 6 Choose the desired access point from the displayed list and click Configure from the drop down arrow.
The radio settings page appears.
Step 7 Scroll down to the Tx Power Level Assignment field, and click Custom.
Custom—indicates that the radio output power is manually controlled by the Tx Power Configuration
setting field.
Step 8 In the Tx Power Level field, select the appropriate power level setting (1 to 5).
Based on the operating channel, the regulatory domain, and the controller power level setting (1 to 5),
the actual transmit power at the access point can be reduced to comply with special regulatory or country
restrictions.
Note Table 1-1, Table 1-2, Table 1-3, and Table 1-4 lists the access point maximum output power
levels supported for its regultory domain when shipped from the factory.
Table 1-6 lists the controller power settings and the corresponding output power levels for two
examples:
• 2.4 GHz (802.11b/g) operation:
– Non-FCC (–N) regulatory domain
– Channel 2 using 11 Mbps data rates
• 5 GHz (802.11a) operation:
– Non-FCC (–N) regulatory domain
– Channel 36 using 36 Mbps data rates
Step 9 Click Apply.

1. The Tx Power Level setting of 1 represents the maximum conducted power
setting for the access point. Each subsequent controller power level (such as
2, 3, 4, etc) represents approximately a 3-dBm reduction in transmit power
from the previous power level.
