Caution To meet regulatory restrictions, the access point and the external antenna must be professionally
installed. The network administration or other IT professional responsible for installing and configuring the
unit is a suitable professional installer. Following installation, access to the unit should be
password-protected by the network administrator to maintain regulatory compliance.
The output power on the access points can be changed only using a Cisco wireless LAN controller
(2600 series or 4400 series), the controllers on a Cisco Wireless Services Module (WiSM), or using
Cisco Wireless Control System (WCS).
Note See the Cisco Wireless LAN Controller Configuration Guide for more details on how to to configure your
access point using the web-browser interface.
Follow these steps to change the access point’s output power to meet local regulations using a controller:
Step 1 Open your Internet browser. You must use Microsoft Internet Explorer 6.0.2800 or a later release.
Step 2 Enter https://IP address (where IP address is the controller’s IP address) in the browser address line
and press Enter. A user login screen appears.

Minimum 5-GHz Radio Power Levels
Table 9-8 lists the minimum power levels supported by the 5-GHz radio for the various channels and
regulatory domains.
Note When the minimum radio power level is reached with a controller power setting (1 to 5), changing the
controller power setting to a lower value does not result in a lower radio output power level. For example,
if the minimum radio power level corresponds to controller level 3, then levels 4 and 5 also correspond
to the same power level.

Changing the Lightweight Access Point Output Power
Changing the Lightweight Access Point Output Power
This section provides instructions for changing the 1520 series access point output power to comply with
the maximum power limits imposed by special regulatory and country restrictions (see the “Minimum
5-GHz Radio Power Levels” section on page 9-12). Follow these instructions to change the output power
settings using a controller and your browser:
Note Administrator privileges may be required in order to change access point settings.
Caution To meet regulatory restrictions, the access point and the external antenna must be professionally
installed. The network administration or other IT professional responsible for installing and configuring the
unit is a suitable professional installer. Following installation, access to the unit should be
password-protected by the network administrator to maintain regulatory compliance.
The output power on the 1520 series access points can be changed only by using a Cisco wireless LAN
controller (2600 series or 4400 series), the controllers on a Cisco Wireless Services Module (WiSM), or
using Cisco Wireless Control System (WCS).
Note See the Cisco Wireless LAN Controller Configuration Guide for more details on how to to configure your
access point using the web-browser interface.
Follow these steps to change the 1520 series access point’s output power to meet local regulations using
a controller:
Step 1 Open your Internet browser. You must use Microsoft Internet Explorer 6.0.2800 or a later release.
Step 2 Enter https://IP address (where IP address is the controller’s IP address) in the browser address line
and press Enter. A user login screen appears.
Step 3 Enter the username and password and press Enter. The controller’s summary page appears.
Note The username and password are case-sensitive.
Step 4 Click Wireless and choose 802.11a/n or 802.11b/g/n under Access Points / Radios . A list of associated
access points appears.
Step 5 Choose the desired access point from the displayed list and click Configure from the drop down arrow.
The the radio configuration page appears.
Step 6 Scroll 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 7 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.

Chapter 9 Cisco Aironet 1520 Series Mesh Access Points Changing the Lightweight Access Point Output Power
Note Table 9-1 and Table 9-5 list the access point maximum output power levels supported for each
regulatory domain when the access point is shipped from the factory.
Table 9-10 lists the controller power settings and the corresponding output power levels for these two
examples:
• 2.4-GHz (802.11b/g) operation:
–
The –E regulatory domain.
–
Channel 3 using 11-Mbps data rates
–
8 dBi antennas
• 5-GHz (802.11a) operation:
–
The –A regulatory domain
–
Channel 149 using 48-Mbps data rates
–
17 dBi antennas
• For this example with 8 dBi antennas, the maximum power allowed for the 2.4-GHz radio is
12 dBi from Table 9-4. This corresponds to a maximum controller power setting of level 2.
• For this example with 17 dBi antennas, the maximum power (Table 9-7) allowed for the 5-GHz radio
is 24 dBi, which corresponds to a maximum controller power setting of level 1.
Step 8 Click Apply.
Step 9 Close your Internet browser.
For additional configuration information, refer to the Cisco Wireless LAN Controller Configuration
Guide.
