Maximum Power Levels and Antenna Gains

IEEE 802.11a

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 D-3indicates the maximum EIRP allowed for each data rate in the IEEE 802.11a regulatory domains.
