Note Mexico is included in the Americas (-A) regulatory domain; however, channels 1 through 8 are for indoor use only while channels 9 through 11 can be used indoors and outdoors. Users are responsible for ensuring that the channel set configuration is in compliance with the regulatory standards of Mexico.

IEEE 802.11g (2.4-GHz Band)

The channel identifiers, channel center frequencies, and regulatory domains of each IEEE 802.11g 22-MHz-wide channel are shown in Table 3-2.

¹For the -E and -I regulatory domains, see the "Maximum Power Levels in Some Regulatory Domains with External Antennas" section.

²In South Korea, the AIR-RM22A-N-K9 is approved only with antenna gains of 6 dBi or less.

³In Australia and New Zealand, the AIR-RM22A-N-K9 is approved only with antenna gains of 6 dBi or less.

⁴Frequencies require DFS (Uniform spreading not required for the -P and -U regulatory domains).

Maximum Power Levels in Some Regulatory Domains with External Antennas

Caution To avoid exceeding maximum conducted power levels in the EMEA (-E) and Israel (-I) regulatory domains when using an external antenna, you must manually set the access point output power level as shown in Table 3-11. The Israel (-I) regulator domain does not support channels 100 to 140.

Note For the latest EMEA (-E) regulatory domain information, refer to the EU Directive 1999/5/EC Compliance Information document that ships with this product.

Changing Access Point Output Power

This section provides instructions for changing the 1200 series access point output power to comply with the maximum power limits imposed by special regulatory and country restrictions (see Table 3-5, Table 3-6, Table 3-7, the "Maximum Power Levels in Some Regulatory Domains with External Antennas" section, and the "Special Country Restrictions" section).

Note Administrator privileges may be required in order to change access point settings.

Note Regulatory domains are set at the factory and cannot be changed by the user.

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 configuration, access to the unit should be password protected by the network administrator to maintain regulatory compliance.

To change the access point output power level, follow these instructions:

Step 1 Use your web-browser to access your access point.

Step 2 When the Summary Status page appears, click Radio0-802.11G or Radio0-802.11A and the radio status page appears.

Step 3 Click Settings and the radio settings page appears.

Step 4 For the 802.11G radio, follow these steps:

a. Scroll down to the CCK Transmit Power (mW) settings and click the desired output power level.

b. For the OFDM Transmit Power (mW) settings, click the desired output power level.

Step 5 For the 802.11A radio, scroll down to the Transmit Power (dBm) settings and click the desired output power level.

Step 6 Scroll down to the bottom of the page and click Apply.

Step 7 Close your web-browser.

For additional configuration information, refer to the Cisco IOS Software Configuration Guide for Cisco Aironet Access Points.
