Appendix A Channels, Power Levels, and Antenna Gains
Maximum Power Levels and Antenna Gains
IEEE 802.11b
The channel identifiers, channel center frequencies, and regulatory domains of each IEEE 802.11b
22-MHz-wide channel are listed in Table A-2
Note Mexico is included in the Americas 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

Note France is included in the EMEA regulatory domain; however, only channels 10 through 13 can be used
in France. Users are responsible for ensuring that the channel set configuration complies with the
regulatory standards of France.
Maximum Power Levels and Antenna Gains
IEEE 802.11a
An improper combination of power level and antenna gain can result in Effective Isotropic Radiated
Power (EIRP) above the amount allowed per regulatory domain. Table A-3 indicates the maximum
power levels and antenna gains allowed for each IEEE 802.11a regulatory domain
