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 that the channel set configuration complies with the regulatory standards of Mexico.

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-3indicates the maximum power levels and antenna gains allowed for each IEEE 802.11a regulatory domain
