Channels, Power Levels, and Antenna Gains
This appendix lists the channels supported by the world's regulatory domains. The appendix also lists the maximum power levels and antenna gains for each regulatory domain.
The following topics are covered in this appendix:
•Channel Sets
•Maximum Power Levels and Antenna Gains
Channel Sets
The channel identifiers, channel center frequencies, and regulatory domains of each 802.11b 22-MHz-wide channel are shown in Table B-1.

Note Mexico is included in the Americas regulatory domain; however, channels 1 through 8 are for indoor use only while chnnels 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.
Note France is included in the ETSI regulatory domain; however, only channels 10 through 13 can be used in France. Users are responsible for ensuring that the channel set configuration is in compliance with the regulatory standards of France.
Maximum Power Levels and Antenna Gains
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-2 indicates the maximum power levels and antenna gains allowed for each regulatory domain.
