Channels and Antenna Settings
This appendix lists the IEEE 802.11g (2.4-GHz) channels, maximum power levels, and antenna gains
supported by the world’s regulatory domains.
The following topics are covered in this appendix:
•
Channels, page B-1
•
Maximum Power Levels and Antenna Gains, page B-3
See the “Configuring Radio Transmit Power (2.4-GHz Radio Only)” in the “Configuring Radio Settings”
chapter for instructions about how to change the radio output power.
Channels
This section describes the channels for 802.11b/g (2.4-GHz) and the 4.9-GHz bands.
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 B-1.

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.
4.9-GHz Band
The channel identifiers, channel center frequencies, and channel width are shown in Table B-2.

Maximum Power Levels and Antenna Gains
Maximum Power Levels and Antenna Gains
IEEE 802.11g (2.4-GHz Band)
An improper combination of power level and antenna gain can result in equivalent isotropic radiated
power (EIRP) above the amount allowed per regulatory domain. Table B-3 indicates the maximum
power levels and antenna gains allowed for each IEEE 802.11g regulatory domain.
Note
To meet regulatory restrictions, the external antenna BR1300 configuration 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.
